Pengpid, S., et al. · 2026 · Psychogeriatrics

Releasing child-rearing responsibilities leads to a measurable uptick in life satisfaction and relationship quality.

Human Wealth™ Synthesis · The Empty Nester transition (TRANS_03) returns hours that were previously committed. Directing those hours toward Psychological Richness (ELEMENT_15) is what turns the recovered time into lived experience rather than drift.

Kumar, S., & Heckman, S. · 2026 · Financial Services Review 34(2)

Among mortgage-free homeowners, holding insurance alongside medium or high financial literacy showed a significantly positive association with financial wellbeing, measured on the CFPB Financial Well-Being Scale. The authors state the relationship may be subject to endogeneity, specifically reverse causality and selection bias, since households with higher baseline financial wellbeing may be more predisposed to purchase insurance.

Human Wealth™ Synthesis · The only source in the corpus connecting an insurance practice to a wellbeing outcome, and it is an association rather than a demonstration. Its own endogeneity caveat must travel with it. The moderation carries the interest: the association holds where financial literacy is medium to high, so this is about cover and understanding what it does, not cover alone.

Althaber, A., Kapelle, N., & Leuze, K. · 2026 · Journal of Marriage and Family

Wealth parity was consistently associated with lower independent money management and higher joint management in both eastern and western Germany, though more weakly in the West.

Human Wealth™ Synthesis · How couples organise money tracks how equally they hold it. Relevant to MET_CF because it shows financial arrangements are an outcome of the relationship's structure rather than a neutral administrative choice.

International Monetary Fund · 2026

Structural inflation floors are rising across developed economies due to deglobalization, energy transition costs, and demographic shifts — eroding purchasing power even in low-CPI environments.

Human Wealth™ Synthesis · Extends the COTI thesis into forward-looking territory. Our vehicle deployment framework must account for structural inflation when constructing long-horizon financial architectures.

PIMCO · 2026

US labor share of income has hit a record low. It was relatively stable at roughly 60 to 65 percent from the 1940s to the 1990s; since the late 1990s it has fallen after every major recession without recovering during expansions, including through the acute post-2020 labour shortages. PIMCO attributes the three-decade decline to weakened labour bargaining power and globalisation among other structural forces.

Human Wealth™ Synthesis · The structural shift from labor income to capital income has direct implications for Financial Security (ELEMENT_06) and career transitions. Advisory must build income diversification beyond wage dependency.

CFP Board · 2026

Defines Financial Planning as a collaborative process that helps maximize a client's potential for meeting life goals through financial advice that integrates relevant elements of the client's personal and financial circumstances. The enumerated scope spans developing goals, managing assets and liabilities, managing cash flow, identifying and managing risks, identifying tax considerations, preparing for retirement, addressing estate and legacy matters, and pursuing philanthropic interests.

Human Wealth™ Synthesis · The certifying body's own account of the practice our System nodes decompose, and it is normative rather than evidential: it says what practitioners must do, never that doing it works. Its value here is the word integrates. The profession already defines planning as acting across a whole life rather than product by product, which is the Composition claim stated by the industry itself.

U.S. House Office of the Law Revision Counsel · 2026

Defines a charitable remainder unitrust as a trust from which a fixed percentage of not less than 5 percent nor more than 50 percent is paid, and provides that charitable remainder annuity trusts and unitrusts are not subject to the taxes imposed by the relevant subtitle for any taxable year.

Human Wealth™ Synthesis · Statute, cited definitionally and never as evidence of an outcome. It establishes what the vehicle IS so the model can describe it accurately; whether it serves any particular household is a planning judgement the statute does not make.

Cornell Legal Information Institute · 2026

Provides that there shall be included in gross income any amount which would be includible were it not part of a qualified rollover contribution, and that the required distribution provisions of section 408(a)(6) and (b)(3) do not apply.

Human Wealth™ Synthesis · Statute, definitional. It fixes the two features that make a Roth conversion a distinct vehicle in the model: the conversion is taxed on the way in, and the required-distribution rules do not follow it.

U.S. Securities and Exchange Commission · 2026

States that knowing how to secure your financial well-being is one of the most important things you will ever need in life, and that you do not have to be a genius to do it.

Human Wealth™ Synthesis · Investor education from the regulator, normative rather than evidential. Useful as a statement of what the public authority thinks a household should know, and it carries no finding about whether knowing it changes anything.

U.S. Department of Labor · 2026

Reports, citing a 2023 Employee Benefit Research Institute survey, that only 51 percent of workers and their spouses have tried to calculate how much they need to save for retirement.

Human Wealth™ Synthesis · A relayed statistic, and the relay must travel with it: the figure is EBRI's and reaches us through a Department of Labor publication. It describes preparation, not outcome.

Sezer, B., Riddell, H., Gucciardi, D. F., et al. · 2025 · Motivation Science

Meta-analysis of 77 studies and 978 effect sizes (N = 39,470) finds pursuing self-concordant goals associated with greater goal effort and attainment, psychological need satisfaction and wellbeing, with associations above r = .40 among the core constructs. The authors state twice that the data are largely correlational and that they cannot draw causal inferences.

Human Wealth™ Synthesis · The meta-analytic basis for Goal Alignment (ELEMENT_10). No decay timeline is available from this source: nothing in it measures decay, and its prospective studies average 153 days. The authors also caution that persistence is not always adaptive, since a goal can become unattainable.

Gladstone, J. J., & Pomerance, J. · 2025 · Journal of Personality and Social Psychology

Across eight studies and 143,461 participants, a one standard deviation increase in dispositional optimism correlates with 16.9 percent more in savings — $1,352 at the median balance of $8,000 and $10,547 at the mean balance of $62,410. The association is stronger among lower-income individuals. Cross-sectional and longitudinal; the authors disclaim causality and name reverse causality as a live alternative.

Human Wealth™ Synthesis · Establishes Optimism (ELEMENT_03) as a financial variable. Relieving a client's cognitive load moves saving behaviour further than financial education alone.

He, Y., Chen, X., & Cao, J. · 2025 · Frontiers in Psychology

In 2,671 valid responses from Chinese college students in Henan Province, recruited by convenience sampling online, psychological richness relates to meaning in life through a chain mediation of sense of coherence and self-compassion.

Human Wealth™ Synthesis · Confirms that Psychological Richness (ELEMENT_15) is not an endpoint but a multiplier — it amplifies meaning, which amplifies purpose, which amplifies the Eudaimonic Ceiling.

Zhang, Y., Yang, H., He, J., & Wang, L. · 2025 · Frontiers in Psychiatry

Retired institutional leaders who derived identity primarily from occupational authority experience severe depression when that authority dissolves.

Human Wealth™ Synthesis · The clinical evidence for Relevance Deprivation Syndrome. Leaders who fuse identity with title face systemic collapse at retirement. Pre-exit identity diversification is a structural requirement.

Sandu Enoiu, R., & Aidar, F. J. · 2025 · Health Nexus

Narrative review of career termination in athletes. Athletic identity supports performance and resilience during a career but can hinder adaptation afterwards by narrowing self-concept and reducing openness to alternative life roles, producing what the authors call the roleless role, characterised by existential uncertainty.

Human Wealth™ Synthesis · An analogue for Relevance Deprivation Syndrome: athletes and executives share single-identity fusion, which points at pre-transition identity architecture as the intervention. The analogy is ours; this is a narrative review of athletes and it compares no populations.

Suade, Y. K. M., Pagiling, M., Montang, S., et al. · 2025 · Proceedings of Forum Manajemen Indonesia's International Conferences

Financial autonomy has a positive effect on financial wellbeing, with financial mindfulness as the mediator, among 281 sandwich-generation respondents across Indonesia. Cross-sectional self-report analysed by SEM-PLS; caregiving burden is not a measured variable.

Human Wealth™ Synthesis · Suggests Autonomy (ELEMENT_09) matters for financial wellbeing in a sandwich-generation sample, working through financial mindfulness. It cannot show a buffer during caregiving transitions (TRANS_01) because caregiving burden was never measured. Indonesian sample, cross-sectional, conference proceedings.

Gashi, S., Kaspar, H., & Holtforth, M. G. · 2025 · Frontiers in Psychology

Informal participation — home gatherings, nature outings, unstructured social contact — is more strongly associated with balanced psychological need satisfaction than formal organizational membership in older adults.

Human Wealth™ Synthesis · Reframes Community Connection (ELEMENT_11): the dinner party outperforms the board seat for autonomy and relatedness. Advisory implication — prioritize informal engagement infrastructure over institutional affiliations in retirement.

Hüsing, P., Huang, W., Maehder, K., et al. · 2025 · Journal of Psychosomatic Research

In 148 German patients with somatic symptom disorder, those classified in a low heart rate variability pattern showed significantly higher somatic symptom severity, depressive symptoms and psychological distress than those with a normal pattern, and stayed higher across 6 and 12 month follow-ups without diverging further. Preprint, not peer reviewed.

Human Wealth™ Synthesis · Supports HRV pattern classification as a feasible marker for identifying an autonomic subgroup, which is what MET_VYR would read. It does not validate polyvagal theory: the paper never mentions it. Note the design limit the authors state — one resting supine measurement cannot show adaptability to stress, which is the construct MET_VYR most wants.

Konishi, M., et al. · 2025 · PLOS One 20(6):e0326528

Psychological richness correlated with positive mental and social health indicators such as confidence in coping and perceived social support, and was also uniquely linked to social isolation and poorer perceived physical health. Confidence in coping showed the strongest positive association at beta = 0.162. Individuals high in richness showed a distinctive profile including more family-related concerns. The authors note the sample was exclusively Japanese and that this limits generalisability.

Human Wealth™ Synthesis · Independent support for ELEMENT_15 as a dimension in its own right, and the study that establishes the Element carries costs as well as benefits. The two findings must be read as a pair: a life of range is associated with coping confidence and with isolation at the same time, which is what makes it a distinct dimension rather than a synonym for doing well.

Teques, A. P., Carreiro, M., Duarte, D., & Teques, P. · 2025 · Healthcare 13(2):100

A pooled effect size of d = 0.383 for the association between retirement and wellbeing across the European literature, described as moderate and statistically significant. Individual study effects ranged from 0.01 to 1.17, which the authors report as significant variability across studies.

Human Wealth™ Synthesis · The only pooled retirement-wellbeing estimate in the corpus, and its range is the more useful number. A spread from essentially nothing to a large effect says the transition does not have an outcome so much as a distribution of outcomes, which is the case for measuring a whole Composition rather than quoting an average at a client.

Kapelle, N., Fremeaux, N., Lersch, P. M., & Leturcq, M. · 2025 · Socio-Economic Review

Cohabitation is positively associated with women's and men's wealth across contexts without meaningful gender differences, and the regulatory treatment of cohabitation plays a more significant role in shaping wealth accumulation than normative acceptance does.

Human Wealth™ Synthesis · Evidence that the legal frame around a relationship, rather than attitudes toward it, is what moves wealth. It places partnership structure inside the Resources domain as something with financial consequences a plan can actually address.

Mauro, R., Di Trani, M., & Simione, L. · 2025 · Frontiers in Psychology 16:1525300

An Italian validation of the Psychologically Rich Life Questionnaire. Applying Kaiser's criterion, only the first item directly measuring psychological richness reached the indicated threshold, confirming the hypothesised one-factor model. The instrument correlates with mindfulness and self-compassion and inversely with factors that tend to undermine wellbeing.

Human Wealth™ Synthesis · Instrument work rather than a finding about lives, and it is part of why ELEMENT_15 is written as a young construct. A measure being validated in a second language is evidence the construct travels; it is not yet evidence about what a rich life does.

Wirz, D., Eden, A., Ulusoy, E., & Ellithorpe, M. · 2025 · PLOS ONE 20(2):e0315596

Shows the prevalence of psychological richness during media use and its positive relationship with wellbeing. A replication with a different scale (n = 291) demonstrates that psychologically rich entertainment experiences may previously have been conflated by some measures of eudaimonic entertainment.

Human Wealth™ Synthesis · Evidence that richness is separable from meaning in practice and not only in theory, since existing instruments were partly confusing the two. A narrow setting, and it is included for the separation it demonstrates rather than for any claim about entertainment.

Gallup · 2025

Gallup reports employee engagement at 21 percent in 2024 and 20 percent in 2025, with actively disengaged running 15 to 17 percent; employee thriving stood at 34 percent in 2025 after peaking in 2022. Gallup categorises employees as engaged, not engaged, or actively disengaged, and reports the three separately.

Human Wealth™ Synthesis · Validates the Systems domain diagnostic: disengagement (rust-out) is the dominant workforce failure mode. Our Engagement (ELEMENT_12) metric operationalizes what Gallup measures at the macro level.

Federal Reserve Board · 2025

37% of American adults cannot cover a $400 emergency without borrowing. This structural fragility persists across income levels due to the Cost of Thriving erosion.

Human Wealth™ Synthesis · The headline statistic that anchors our Financial Capital Ledger. The $400 threshold is diagnostic, but the $40,000 Security Floor is the structural intervention — six buckets designed to eliminate the emergency liquidity gap.

OECD · 2025

Access to adult learning is unequally distributed across OECD countries and reproduces initial disadvantage: participation in non-formal learning averages about 43 percent, but 61 percent among tertiary-educated adults against 19 percent among those with below upper secondary education. The gap is qualitative as well as quantitative — disadvantaged adults are over-represented in courses on operating machinery and security protocols, advantaged adults in project management, languages and numeracy.

Human Wealth™ Synthesis · Confirms that financial literacy alone is an insufficient intervention. Our approach invests in Optimism (ELEMENT_03) and cognitive offloading rather than literacy training.

Financial Planning Review · 2025

Baseline wave of a 10-year CFP Board study of 4,027 mass affluent US households. Descriptively, 31 percent of the CFP-advised group strongly agreed they were confident of achieving their financial goals against 22 percent of the unadvised, and 51 percent against 28 percent reported living comfortably. The authors state that identifying an effect of advice is plagued by selection effects, so these gaps cannot yet be read as a result of advice.

Human Wealth™ Synthesis · Does not validate a multiplier: nothing here compounds, and the study designed to answer the advice-value question has only just started. It is funded by the CFP Board, whose credential it measures. Treat it as a baseline to revisit as later waves publish, not as evidence that advice causes wealth.

Chariot · 2025

Among 54 participating nonprofits representing $26.1 billion in giving data, median DAF revenue growth from 2021 to 2025 was +75 percent against +9 percent for non-DAF revenue. Of 50,000 existing donors who switched to DAF giving, the average increase was more than 10x their own prior giving level, and nearly half more than doubled their annual giving.

Human Wealth™ Synthesis · Supports the donor-advised fund as a generativity structure: it turns surplus into directed giving, which is legacy intent made practical. Note the interest — Chariot sells DAF payment tooling and the report is its own marketing study of self-selected nonprofits, so the switcher effect is not a controlled comparison.

AARP Public Policy Institute · 2025

63 million American adults, almost a quarter of all adults, provided ongoing care in 2025, a 45 percent increase since 2015. 29 percent are sandwich generation caregivers, rising to 47 percent among those under 50. Caregivers spend 27 hours per week on average and 24 percent provide 40 or more. Among working caregivers, 31 percent used up short-term savings, 22 percent took on more debt and 19 percent paid bills late.

Human Wealth™ Synthesis · The caregiving surge is the dominant transition trend, and this report gives the hidden cost directly rather than as an expense line: a third of working caregivers using up short-term savings, a fifth taking on debt. That is what the Shadow Liability Index (MET_SLI) measures.

OECD Publishing · 2025

Global growth is projected to slow from 3.3 percent in 2024 to 2.9 percent in 2026 under higher tariffs and high policy uncertainty. The US effective tariff rate reached an estimated 19.5 percent at the end of August 2025, the highest since 1933, and US growth is projected to fall from 2.8 percent in 2024 to 1.5 percent in 2026, which the OECD attributes to tariffs and a drop in net immigration. G20 headline inflation is projected to fall from 3.4 percent in 2025 to 2.9 percent in 2026.

Human Wealth™ Synthesis · Macro context for Financial Security (ELEMENT_06) and an input to the Personal Cost of Thriving Index (MET_COTI). Higher tariffs and persistent inflation raise the weeks of labor a given standard of living costs, so the same objective security floor buys less stability. Softening labor markets lengthen the time a career pivot takes, which raises the runway the Adaptability Quotient (MET_AQ) requires.

GAO · 2025

Institutional friction, meaning the learning, compliance and psychological costs of navigating paperwork and bureaucracy, discourages people from acting in their own interest. The American public spent 10.5 billion hours completing federal paperwork in 2023, and roughly $140 billion in authorised benefits goes unclaimed each year because the process cost exceeds the bandwidth available to claim it. The burden falls hardest on people in poor mental health or with limited social networks.

Human Wealth™ Synthesis · A primary input to the Bandwidth Tax (MET_BW_TAX). It shows friction blocking external conditions from converting into lived experience: the benefit exists, and it never reaches the person because the administrative drag is too high. The distributional finding matters most, since the load is heaviest exactly where there is least capacity to absorb it.

LIMRA / Life Happens · 2025

Reports that 51% of American adults say they have some sort of life insurance coverage, individual or group, and that 40% of American adults believe they need more.

Human Wealth™ Synthesis · Prevalence only, and it is commercial_research from publishers with a direct interest in the result: both organisations exist to grow the market this survey measures. It may describe how common cover is and may never support a claim that cover improves an outcome.

Internal Revenue Service · 2025

States that the primary duties of a personal representative are to collect all the decedent's assets, pay the decedent's creditors, and distribute the remaining assets to the heirs or other beneficiaries.

Human Wealth™ Synthesis · The administrative work that follows a death, set out by the authority that requires it. It is the concrete content of the burden the corpus records survivors describing, and it belongs beside the estate chapter as fact rather than as sentiment.

Internal Revenue Service · 2025

States that you must begin receiving required minimum distributions by April 1 of the year following the year you reach age 73.

Human Wealth™ Synthesis · The specific deadline behind the decumulation obligation, cited definitionally. It is the kind of fact a plan must get exactly right and a chapter must not generalise from.

U.S. Government Accountability Office · 2025

Sets out learning costs as a category of administrative burden: resources expended to learn about a program, its eligibility requirements, and how to comply with those requirements.

Human Wealth™ Synthesis · The government auditing its own friction, and naming a cost that never appears on a statement. Learning cost is the closest official vocabulary to the bandwidth mechanism this issue argues from.

Internal Revenue Service · 2025

States who must file, noting that the amount of income you can receive before you must file a return has been increased.

Human Wealth™ Synthesis · The baseline obligation behind Tax Planning as a System, cited definitionally. It anchors the chapter's claim that tax is a compliance burden borne by the household before it is an optimisation opportunity.

Eloundou, T., Manning, S., Mishkin, P., & Rock, D. · 2024 · Science

Rubric-based estimate that around 80 percent of the US workforce could have at least 10 percent of work tasks affected by LLMs, and about 19 percent could see at least half affected, with higher-income jobs facing greater exposure. The authors define exposure without distinguishing labour-augmenting from labour-displacing effects, and make no prediction about adoption timing. Three of four authors are at OpenAI and GPT-4 is one of two classifiers.

Human Wealth™ Synthesis · We measure the client's Adaptability Quotient (MET_AQ) against task exposure rather than predicted job loss. The paper supports the exposure estimate and explicitly declines to supply a timeline, so any urgency framing must rest on something else.

Cao, Y., & Ma, H. · 2024 · Frontiers in Psychology

Ego identity status correlates with goal self-concordance, which ranked from highest to lowest across four statuses beginning with identity achievement. In 292 Chinese students cross-sectionally, with 98 followed longitudinally.

Human Wealth™ Synthesis · Confirms that Identity Lag (common in transitions) disrupts goal quality. Advisors must address identity work before setting financial targets for clients in transition.

Pew Research Center · 2024

44 percent of young adults aged 18 to 34 say they received financial help from their parents in the past year, most commonly for household expenses and phone or streaming bills. 45 percent say they are completely financially independent, rising to 67 percent of those in their early 30s. Among parents who helped, 36 percent say doing so hurt their own financial situation at least some.

Human Wealth™ Synthesis · Backs the Crowded Nest Index (MET_CNI). The figure that actually carries the argument is the parents' side: 36 percent of parents who helped say it hurt their own financial situation, which is the unfunded liability made visible from the payer's point of view.

Journal of Applied Psychology · 2024

Adult children's financial anxiety is associated with their parents' own financial anxiety and, through it, with intentions to delay retirement. Found across correlational studies in the UK, US and Singapore; the retirement link did not replicate in Indonesia, where the crossover ran through social undermining and financial expenditure instead.

Human Wealth™ Synthesis · The mechanism behind the Crowded Nest Index. Financial stress does travel upward within family systems, so a client's position depends on their children's financial architecture too. The correlations are small to moderate (r = .19 to .33), all studies are correlational, and the crossover did not reach the retirement decision in every country tested.

U.S. Bureau of Labor Statistics · 2024

14% of the civilian population (38.2 million people) provide unpaid eldercare. Intensity concentrated in 55-64 age group (24%) and 45-54 age group (19%).

Human Wealth™ Synthesis · The age-intensity concentration means caregiving peaks precisely when retirement accumulation is most critical. This timing conflict is why we model caregiving as a systemic threat to Financial Security and Vitality simultaneously.

Internal Revenue Service · 2024

States that required minimum distributions are minimum amounts that IRA and retirement plan account owners generally must withdraw annually.

Human Wealth™ Synthesis · Taxpayer guidance, definitional. It supplies the obligation that makes decumulation a scheduled event rather than a choice, which is part of what the Third Act Index treats as the structural floor.

Killingsworth, M. A., Kahneman, D., & Mellers, B. · 2023 · Proceedings of the National Academy of Sciences (PNAS)

Happiness continues to rise with income beyond $75,000, but the effect is heavily muted for individuals in the least happy cohort.

Human Wealth™ Synthesis · Confirms that holdings alone do not guarantee a good day. Financial capital lifts Daily Affect (ELEMENT_16) only where friction is low and Psychological Richness (ELEMENT_15) is present.

Sun, J., et al. · 2023 · Frontiers in Psychology

Eudaimonic motivation predicts life satisfaction more stably than hedonic motivation. The mechanism is goal conflict: pursuing immediate pleasure puts a person at odds with their longer commitments, which produces mixed emotions and drags satisfaction down. Measured in 788 Chinese university students aged 16 to 25 across 13 provinces.

Human Wealth™ Synthesis · Anchors Meaningful Life (ELEMENT_13) as the more stable source of satisfaction in the Wellbeing lens. Goals aligned with what a person actually values produce less internal argument, which is why purpose-oriented planning holds up where consumption-oriented planning does not.

Coelho, A., Lopes, M., Barata, M., Sousa, S., Goes, M., et al. · 2023 · International Journal of Environmental Research and Public Health

In 1,330 adults aged 55 to 84, education, stress, spirituality, optimism, support from friends and physical-health quality of life relate to purpose in life for both working and retired people. What differs by life stage is the rest: age, marital status and environmental quality of life explain purpose among the retired, while social-support quality of life explains it among those still working. Cross-sectional.

Human Wealth™ Synthesis · Gives the Third Act Index (MET_TAI) something concrete to rebuild toward, because it names what carries purpose on each side of the retirement boundary rather than treating purpose as one undifferentiated thing. Being cross-sectional, it cannot show what happens at the transition itself.

Olson, J. G., & Rick, S. I. · 2023 · Journal of the Association for Consumer Research

Partners' differences in subjective financial knowledge reliably predict their relative influence over shared financial decisions, while differences in objective financial knowledge generally do not.

Human Wealth™ Synthesis · Who feels more knowledgeable shapes a couple's decisions more than who is more knowledgeable. It is a caution for any advisory relationship that reads the more confident partner as the more informed one.

American Compass · 2023

The index counts the weeks of work needed to cover five middle-class costs for a family of four: food, housing, health care, transportation and higher education. It was 39.7 weeks in 1985, when those costs totalled $17,586 against a median weekly income of $443 for a man aged 25 or over in full-time work, and 62.1 weeks in 2022, when they totalled $75,732 against $1,219.

Human Wealth™ Synthesis · The source our Cost of Thriving reading is built on, and the reason a high income can still feel scarce. Its method is disputed: Winship and Horpedahl (SRC_39) accept the arithmetic and reject the approach, and their corrected series rises 10 percent rather than 56. Present the measure as contested and give the range.

Journal of Workplace Learning · 2023

A qualitative study of 696 software-industry workers identified 21 barriers to flow. The most-mentioned was work not presenting enough cognitive challenge (152 mentions), narrowly ahead of interruptions and distractions (149), which include meetings and task switching. Situational barriers drew 503 mentions in total and personal barriers 350.

Human Wealth™ Synthesis · Names what blocks flow rather than how much of it people get. Our Engagement (ELEMENT_12) metric targets both halves the study found: too little cognitive challenge, which is rust-out measured and counted, and too much interruption. The evidence is qualitative and from software workers with a mean age of 32.

International Journal of Environmental Research and Public Health · 2023

Glass had the best restorative potential among common interior home materials and metal is not recommended for restorative home design; the authors also raise doubts about wood.

Human Wealth™ Synthesis · Environmental Quality (ELEMENT_07) extends to material science: the physical surfaces surrounding a client either restore or deplete cognitive bandwidth. Advisory design should audit the built environment.

AEI Center on Opportunity and Social Mobility · 2023

Accepts the arithmetic behind the Cost-of-Thriving Index and rejects its method. Correcting the cost estimates puts the rise at 10 percent rather than 56, from 37.9 weeks to 41.7. Adjusting for quality improvements leaves a four-week rise, and accounting for falling federal taxes or widening the earnings series to all full-time workers makes the cost of thriving fall, by 7.5 weeks after tax for the broader group. On conventional measures, cost-adjusted earnings rose 19 percent before tax and 34 percent after.

Human Wealth™ Synthesis · The counterweight to SRC_03, held so the Cost of Thriving reading is presented as contested rather than settled. Neither document is peer reviewed and both come from advocacy-adjacent institutions, which belongs in the prose. What survives the disagreement is the direction and the felt experience, not the 62.1 figure.

American Compass · 2023

Expresses the cost of a stipulated basket as weeks of income for a median man aged 25 or older working full time. In 1985 the index stood at 39.7, with costs of $17,586 against weekly income of $443, and in 2022 it stood at 62.1. The interpretive claim is that the typical man working full time in 1985 could support a family on 40 weeks of income and still have roughly 20% of the year left.

Human Wealth™ Synthesis · The origin of the weeks-of-work idea our own Personal Cost of Thriving Index borrows, and it is commercial_research from an advocacy think tank, not a refereed paper. It may never be cited without Winship and Horpedahl, who reproduced the arithmetic and rejected the method. What survives the critique is the unit: money expressed as time is a measure a household can act on.

Exit Planning Institute · 2023

Reports that when business owners were asked in 2013 whether they had sought outside advice regarding their exit, 38% said they had, against a higher share a decade later.

Human Wealth™ Synthesis · Prevalence of advice-seeking among business owners, and commercial_research from a body that certifies exit planners. Bounded to describing practice: it says how many owners sought advice, never that seeking it helped.

Oishi, S., & Westgate, E. C. · 2022 · Psychological Review (APA)

Proposes psychological richness, characterised by variety, interestingness and perspective change, as a third dimension of a good life alongside happiness and meaning. The authors call the three related but distinct, decline to claim there are only three, and report that in coded obituaries psychologically rich lives were rated less happy.

Human Wealth™ Synthesis · Maps to Psychological Richness (ELEMENT_15). Not a diagnostic: the paper offers no clinical application, no cut-point and no intervention, and studies students, national panels and obituaries rather than executives. The tension it does license is real and sharper — the paper assigns money, time and stable relationships to the happy life and curiosity to the rich one, and a substantial minority say they would trade happiness for richness.

Ryan, R. M., Duineveld, J. J., Di Domenico, S. I., et al. · 2022 · Psychological Bulletin

A narrative synthesis of 60 meta-analyses finds support for SDT's motivational taxonomy and for the proposition that satisfaction of the needs for autonomy, competence and relatedness predicts wellbeing while their frustration predicts ill-being. The authors note that the meta-analyses rely typically on cross-sectional data, and Richard Ryan, who co-originated the theory, is the lead author.

Human Wealth™ Synthesis · The heaviest evidence base in our corpus for ELEMENT_09 and ELEMENT_10. Its most useful material for this report is on money: a meta-analysis of 259 samples finds materialism associated with lower wellbeing, while the authors guard against over-reading it, noting that money can provide security and safety and that the harm lies in extrinsic pursuits predominating.

Porges, S. W. · 2022 · Frontiers in Integrative Neuroscience

A review restating the dissolution hierarchy: under threat the defence repertoire is expressed first as mobilization requiring the sympathetic nervous system, then as immobilization controlled by an older unmyelinated vagal pathway. Porges names the triad as social engagement, fight/flight and shutdown.

Human Wealth™ Synthesis · Extends the Vitality Gate Rule with updated clinical protocols. The dissolution hierarchy explains why grieving or divorcing clients cannot engage in financial planning — their social engagement system is offline.

Delgado, M. · 2022 · Social Sciences & Humanities Open

An exploratory phenomenological study of five survivors of the 2018 Paradise Camp Fire, all homeowners, proposes that the pleasant feelings of home reflect parasympathetic restoration, and offers a thirteen-topic instrument for identifying what home means to a displaced person. No physiological measure was taken; the author calls the findings provisional and non-transferable to other populations.

Human Wealth™ Synthesis · Proposes rather than validates Environmental Quality (ELEMENT_07) as a physiological input. If ELEMENT_07 needs a physiological warrant, this paper cannot supply it. What it does supply is usable: a thirteen-topic instrument for eliciting what home means to a particular person, which suits a consultation better than an assertion does.

Systematic review of 154 longitudinal cohort studies covering 27 subtypes of persistent somatic symptoms, which affect up to 10 percent of the general population. Strong evidence was found in every biopsychosocial domain at once: biological, psychological, interpersonal, contextual and health behavioural. The authors conclude that reducing predictors to a single factor or domain may be too restrictive.

Human Wealth™ Synthesis · The general-population counterpart to LIT_A_27, which is a clinical sample. It is also a constraint on our own metric design: a Vitality Yield Ratio (MET_VYR) read as one signal sits against a review whose headline is that one-domain explanations do not hold.

Brandt, M., Kaschowitz, J., & Quashie, N. T. · 2022 · Aging & Mental Health 26(8):1589-1596

Less wealthy caregivers do not experience steeper wellbeing declines when opting into caregiving. The least wealthy start caregiving at a lower baseline level of life satisfaction and the wealthiest start higher, with the size of the decline similar across the distribution.

Human Wealth™ Synthesis · Contradicts the premise that financial runway predicts adaptation, which is a premise MET_AQ inherits. Wealth sets where a person begins and not the shape of what follows, so a metric claiming to measure adaptability cannot use the balance sheet as its proxy. We quote it making that contradiction rather than paraphrasing around it.

Schofield, H., & Venkataramani, A. S. · 2021 · PNAS

Poverty confers a double tax: it reduces not only the level of consumption but the enjoyment obtained from a given unit of it. In a randomised experiment with 526 low- and middle-income informal-sector workers in Chennai, simulating features of scarcity cut rated enjoyment by 0.22 SD, with the largest effect on food. The financial-stress effect was concentrated in the below-median half of the sample and null above it.

Human Wealth™ Synthesis · The empirical anchor for the Bandwidth Tax (MET_BW_TAX): friction crowds out the attention that Engagement (ELEMENT_12) and Daily Affect (ELEMENT_16) require, which is why relieving load raises lived experience without adding a dollar of Financial Security (ELEMENT_06). The evidence supports this for people under financial strain; the authors note in a footnote that the mechanism may reach the rich and say they chose not to test it, so extending the claim upward must be flagged as their declined hypothesis.

Hoffmann, A. O. I., McNair, S. J., & Pallant, J. · 2021 · European Journal of Marketing

Latent transition analysis of a nationally representative US sample across three months finds an asymmetry: the lower-vulnerability state is fragile and easily fallen out of, while the higher-vulnerability state is sticky. Financial self-efficacy explains which state a person is in; consideration of future consequences is what predicts movement between them.

Human Wealth™ Synthesis · Explains why the durability of an external loss is set by an internal capacity. The variable this study credits with MOVEMENT between states is consideration of future consequences, not self-efficacy, which explains only which state a person is in. The paper studies neither divorce nor bereavement, so applying it to TRANS_06 is our extension, and the window observed is three months.

Killingsworth, M. A. · 2021 · PNAS 118(4):e2016976118

Both experienced and evaluative wellbeing increased linearly with log income, with an equally steep slope for higher earners as for lower earners, and no evidence of an experienced wellbeing plateau above $75,000 a year. The author notes the earlier finding rests on a measure of experienced wellbeing that may or may not indicate actual emotional experience, being retrospective and dichotomous, and that participants here were employed US adults aged 18 to 65 reporting household incomes of at least $10,000.

Human Wealth™ Synthesis · The direct contradiction of Kahneman and Deaton, held in the corpus beside it rather than instead of it. The pair is the clearest demonstration available that a finding about money and wellbeing depends on how wellbeing was measured, which is why ELEMENT_16 exists as a separate Element.

Bonanno, G. A. · 2021 · European Journal of Psychotraumatology 12(1):1942642

The correlates of resilient outcomes are generally so modest that it is not possible to accurately identify who will be resilient, a problem the author calls particularly pernicious when those correlates are championed for building resilience. Predictors show only modest overall effects because they are not beneficial in every situation or at every time. The constructive alternative offered is flexible self-regulation, whose primary component is three sequential steps later dubbed the flexibility sequence.

Human Wealth™ Synthesis · The most direct objection in the corpus to our own MET_AQ, since that index is a composite of exactly the kind of correlates this paper says cannot identify anyone. We hold it because an instrument improved by its critics is more trustworthy than one that never met any, and the flexibility sequence is the shape the metric should take: a practice a person runs, not a trait they are scored on.

Tocchioni, V., Berrington, A., Vignoli, D., & Vitali, A. · 2021 · Demography 58(5):1843-1865

The likelihood of becoming a parent has declined among homeowners while childbearing rates among private renters have remained stable. The authors state this questions the classical micro-level assumption of a positive link between home ownership and the transition to parenthood, at least among Britain's Generation Rent. Interacting anticipatory moves with tenure produced a similar effect across tenure groups.

Human Wealth™ Synthesis · A finding that contradicts an assumption our own model could easily have inherited, that securing a home precedes starting a family. The authors frame it as a question raised rather than a link disproved, and the chapter should keep that framing.

Pena-Longobardo, L. M., Rodriguez-Sanchez, B., & Oliva-Moreno, J. · 2021 · Economics and Human Biology 43:101049

In the short term, those who became widowed had worse wellbeing and mental health along with a greater probability of receiving care. The authors report results in line with hedonic treadmill models for wellbeing, mental health and deaths, while noting this conclusion does not seem to hold across every outcome, and they did not have information about how the spouse died.

Human Wealth™ Synthesis · Widowhood read across several outcomes at once, where some return toward baseline and others do not. It supports acting at the transition itself rather than later, and it pairs with Streeter, whose finding is that the financial and emotional halves move independently.

CFPB / SEC joint advisory · 2021

Defines diminished financial capacity as a term used to describe a decline in a person's ability to manage money and financial assets to serve their own best interests.

Human Wealth™ Synthesis · A definition issued jointly by two regulators, which makes it the authoritative wording rather than ours. It names a risk the Composition has to be able to represent: capability can fall while resources stay intact.

Kaiser, T., Lusardi, A., Menkhoff, L., & Urban, C. · 2020 · NBER Working Paper 27057

A meta-analysis of 76 randomized experiments with a total sample size of over 160,000 individuals, studying the causal effects of financial education programs on financial knowledge and downstream behaviours.

Human Wealth™ Synthesis · Held deliberately beside Fernandes, Lynch and Netemeyer, which reaches the opposite conclusion on the same question. Two meta-analyses disagreeing is not a problem to resolve before publishing; it is the honest state of the field, and any claim this issue makes about financial education must show both. Stored as a working paper rather than the version of record.

Streeter, J. L. · 2020 · The Journal of the Economics of Ageing

Women experience a 22% income reduction and a 10% wealth loss in the first two years after losing a spouse, and widows have more earnings than before widowhood, indicating a return to work whose increase is inadequate to offset the loss. Men's financial conditions stay relatively stable while their emotional and mental health worsen sharply, through rising loneliness, depression and sadness.

Human Wealth™ Synthesis · The clearest case in the corpus that a transition can leave one Element untouched and collapse another. A plan that tracked only the balance sheet would have recorded a widowed man as unaffected. It is the single strongest argument the issue has for measuring more than money.

Sunstein, C. R. · 2019 · SSRN / Duke Law Journal

Paperwork burdens, understood as sludge, reduce access to licenses, programmes and benefits, and fall hardest on the poor, the elderly, the disabled and on women, who do a disproportionate share of household administration. The US government imposed 9.78 billion hours of paperwork burdens in 2015. A law review essay with no data of its own, and a fifth of it sets out five legitimate purposes for sludge.

Human Wealth™ Synthesis · We formally quantify this friction as Administrative Load (OBJ_TIME_ADMIN). Our Family Office architecture is designed explicitly to eradicate sludge from the client's cybernetic system.

Kettlewell, N., Morris, R. W., Ho, N., et al. · 2019 · SSM - Population Health

In a large population cohort analysed with within-person fixed effects, marriage, retirement and childbirth each raised cognitive (evaluative) wellbeing but had no overall effect on affective wellbeing. Affective adaptation to positive events occurred by two years, while some events retained ongoing cognitive benefits. Promotion and being fired had little independent effect once co-occurring events were controlled.

Human Wealth™ Synthesis · Maps life events onto the distinction the Wellbeing lens already draws between Satisfying Life (ELEMENT_14, evaluative) and Daily Affect (ELEMENT_16, moment to moment). A transition can move one without durably moving the other, which is exactly the split a single wellbeing grade erases and a four-element portrait preserves.

Rojas-Rueda, D., Nieuwenhuijsen, M. J., Gascon, M., Perez-Leon, D., et al. · 2019 · The Lancet Planetary Health 3(11):e469-e477

Seven of nine studies (78%) found a significant inverse relationship between surrounding greenness per 0.1 NDVI within 500 m and all-cause mortality, which means two did not. The pooled hazard ratio per increment is small. The authors note that NDVI measures neither the quality of greenness nor accessibility to it, and call these notable limitations.

Human Wealth™ Synthesis · Establishes the direction of the environment-mortality association at population scale while naming the measurement limit that stops it being read as a prescription. A satellite index cannot distinguish a park you can reach from a verge you cannot, so ELEMENT_07 claims direction and declines magnitude.

Ong, Q., Theseira, W., & Ng, I. Y. H. · 2019 · PNAS 116(15):7244-7249

Comparing low-income Singaporean debtors before and after a one-off, unanticipated debt-relief programme worth several months of household income, those with more debt accounts paid off experienced greater improvements in cognitive functioning and reported anxiety. The evidence is quasi-experimental rather than randomised, and the authors say identification concerns cannot be completely eliminated.

Human Wealth™ Synthesis · The closest thing in the corpus to a financial intervention acting on the bandwidth mechanism. Where Mani establishes that scarcity consumes cognitive capacity, this removes a source of scarcity and measures what returns. The population is low-income debtors and the design is quasi-experimental, so it evidences a mechanism rather than a service.

Pohlan, L. · 2019 · Journal of Economic Behavior and Organization 164:273-299

Combining inverse propensity score weighting with a difference-in-differences approach on German linked survey and administrative data, job loss has particularly detrimental effects on the subjective perception of social integration, life satisfaction and access to economic resources. The effects are long-lasting, grow more profound the longer unemployment continues, and persist following reemployment.

Human Wealth™ Synthesis · One of the few genuinely causal designs in the corpus, and it shows a transition damaging Elements far from the pay cheque. That the damage persists after reemployment is the finding that matters for planning: restoring the income does not restore the rest, which is the argument for measuring a whole Composition through a transition.

European Commission, ESPN Flash Report 2019/17 · 2019

Reports that the Finnish basic income experiment had no significant impact on employment, while leading to less bureaucracy as well as higher life satisfaction and wellbeing among recipients.

Human Wealth™ Synthesis · A clean separation of two outcomes that are usually argued as one. The experiment was designed to test employment and found nothing, and it found wellbeing anyway. Any planning or policy argument treating work and wellbeing as a single lever has to reckon with a trial that moved one and not the other. A two-page flash report, so no design or sample detail may be attached to it.

Clark, C., & Paunovic, K. · 2018 · International Journal of Environmental Research and Public Health 15(11):2400

Given the predominance of cross-sectional studies, most evidence linking environmental noise to quality of life, wellbeing and mental health was rated as very low quality, with effects observed only for some noise sources and outcomes. Ninety percent of the papers were cross-sectional, with fewer studies of longitudinal or intervention design.

Human Wealth™ Synthesis · The honest state of the noise literature, and the reason ELEMENT_07 claims a direction rather than a magnitude. A systematic review that grades its own evidence as very low quality is more useful to us than one that does not, because it tells the chapter exactly how firmly to write.

Leopold, T. · 2018 · Demography 55(3):769-797

Men's disproportionate strain of divorce is transient whereas women's is chronic, and the key domain of large and persistent gender difference is women's disproportionate losses in household income. Men were more vulnerable to short-term consequences for subjective wellbeing, but postdivorce adaptation alleviated those gender differences. A medium-term view across multiple outcomes showed more similarity than difference.

Human Wealth™ Synthesis · The transition where the financial and the emotional losses land on different people on different timetables. It is the clearest argument in the corpus that a single summary of a transition is misleading, since which spouse is worse off depends entirely on which outcome and which year you measure.

Deci, E. L., Olafsen, A. H., & Ryan, R. M. · 2017 · Annual Review of Organizational Psychology and Organizational Behavior

Workplace contexts that support competence, autonomy and relatedness predict autonomous motivation, which in turn predicts less burnout, work exhaustion and turnover alongside greater satisfaction, commitment and performance. A narrative review of employee samples in the US, Canada and Norway; it reports no effect size.

Human Wealth™ Synthesis · The foundation of our B2B Organizational Human Wealth™ offering. Rust-Out is our term, not SDT's; the measurable construct nearest to it is need frustration. The review's sharper finding is that the active thwarting of autonomy predicts ill-being more strongly than low support does, which is a better hook than the one we had.

Consumer Financial Protection Bureau · 2017

Defines financial well-being as a state of being wherein a person can fully meet current and ongoing financial obligations, can feel secure in their financial future, and is able to make choices that allow them to enjoy life.

Human Wealth™ Synthesis · The validated instrument for the outcome this journal is named after, and the definition our own Financial Security Element is written against. Its four-part structure — meeting obligations, feeling secure, and being able to choose — is itself an argument that financial wellbeing is not one number.

Infurna, F. J., & Luthar, S. S. · 2016 · Perspectives on Psychological Science 11(2):175-194

Re-examining spousal loss, divorce and unemployment in the same German panel data used by prior reports, and relaxing the stringent assumptions those reports applied, the authors consistently found resilience to be the least rather than the most common trajectory. They warn against categorical statements about rates of resilience, and show that trajectory findings vary substantially with statistical model specification.

Human Wealth™ Synthesis · The corpus's sharpest methodological contradiction, and it lands on our own instruments. If the prevalence of resilient trajectories moves with model specification, a metric that scores adaptability inherits that instability. We hold it beside Bonanno rather than choosing between them, and it is the reason MET_AQ is presented as a practice to run rather than a rate to quote.

James, P., Hart, J. E., Banay, R. F., & Laden, F. · 2016 · Environmental Health Perspectives 124(9):1344-1352

Women in the highest quintile of cumulative average greenness within 250 m of home, accounting for changes of residence during follow-up, had a 12% lower rate of all-cause non-accidental mortality. The authors report that the association may be at least partly mediated by physical activity, particulate matter under 2.5 micrometres, social engagement, and depression.

Human Wealth™ Synthesis · The clearest map in the corpus of one Element reaching another. Read through the Composition, the mediators are not confounds to be explained away but the route itself: Environmental Quality acting through Vitality, Community Connection and Daily Affect. It is the empirical anchor for the claim that the parts of a life fund each other.

Haushofer, J., & Shapiro, J. · 2016 · Quarterly Journal of Economics 131(4):1973-2042

A randomised trial of unconditional cash transfers among rural Kenyan households in extreme poverty. Recipients experienced large increases in psychological wellbeing, and the study found no overall effect on levels of the stress hormone cortisol, with differences across some subgroups. Monthly transfers were more likely to improve food security while lump-sum transfers were more likely to be spent on durables.

Human Wealth™ Synthesis · The corpus's strongest causal evidence that money moves wellbeing, and the population caveat travels with it: this is extreme poverty, not a wealth-management readership. Two further findings matter for us. Reported wellbeing and a biological stress marker moved apart, so self-report and physiology are not interchangeable. And the same total transfer did different things depending on its structure, which is the premise of Cash Flow as a System.

Ruberton, P. M., Gladstone, J., & Lyubomirsky, S. · 2016 · Emotion 16(5)

Readily accessible sources of cash are of unique importance to life satisfaction, above and beyond other financial measures. The authors state their correlational data do not permit causal inferences, while finding that immediate access to money plays a unique role in explaining the relationship.

Human Wealth™ Synthesis · The only source in the corpus that speaks to Investment Management and Cash Flow at once, and it separates the balance you can reach from the balance you own. It is the empirical case for treating accessible cash as its own quantity in the model rather than as a line in net worth, and it is an association that says so itself.

Broese van Groenou, M. I., & De Boer, A. · 2016 · European Journal of Ageing 13(3):271-279

Cutbacks in professional care are increasing demand for informal care considerably, from both kin and non-kin.

Human Wealth™ Synthesis · The structural context behind the caregiving transition: informal care is not a private choice made in isolation but a demand created partly by policy. It sets up why caregiving arrives unplanned in so many financial lives.

Steptoe, A., Deaton, A., & Stone, A. A. · 2015 · The Lancet

In the English Longitudinal Study of Ageing, 9,058 adults aged 50 and over tracked for 8.5 years, 29.3 percent of the lowest eudemonic wellbeing quartile died against 9.3 percent of the highest, independent of age, sex, wealth, education, baseline physical and mental health and health behaviours. The paper also reviews, from other researchers' work, an association between positive wellbeing and reduced daytime cortisol output.

Human Wealth™ Synthesis · The strongest evidence in the corpus that wellbeing is not reducible to financial position: the survival association holds with total household wealth in the model. The Vitality Yield Ratio (MET_VYR) reads that. Note the authors' own limit — they say it is not yet known whether wellbeing is sufficiently modifiable by psychological, societal or economic intervention to test effects on health.

Unpaid family caregivers forfeit trillions in lost wages and compound interest, while simultaneously degrading their own long-term health metrics.

Human Wealth™ Synthesis · We define this as the Shadow Liability Index (MET_SLI). Ignoring this unfunded obligation breaks the financial plan; we neutralize it via Long-Term Care architecture.

DiGiacomo, M., Lewis, J., Phillips, J., Nolan, M., & Davidson, P. M. · 2015 · BMC Women's Health

Bereaved spouses report feeling wholly unprepared for the executor role and describe it as very hard to carry out while grieving. Protracted processes for transferring property titles and closing accounts drive high anxiety and demoralisation. Moving from a joint to a single pension can cut public income support by 40 percent. Bereaved managers take significantly less financial risk for 6 to 12 months following a loss.

Human Wealth™ Synthesis · Informs Self-Efficacy (ELEMENT_02) and Financial Security (ELEMENT_06), and feeds the Bandwidth Tax (MET_BW_TAX) through administrative hours. The demoralisation is a collapse in self-efficacy that slows every downstream decision. The 6 to 12 month risk-aversion window is the case for pre-structuring an estate so a survivor is not building financial competence and grieving at the same time.

Holt-Lunstad, J., Smith, T. B., Baker, M., Harris, T., & Stephenson, D. · 2015 · Perspectives on Psychological Science 10(2):227-237

Weighted average effect sizes were social isolation OR = 1.29, loneliness OR = 1.26, and living alone OR = 1.32. Results differ across participant age, with social deficits more predictive of death in samples with an average age younger than 65.

Human Wealth™ Synthesis · The companion to the 2010 meta-analysis, separating objective isolation from the felt experience of loneliness and finding both carry mortality risk. The age finding matters for a wealth readership: the effect is stronger below 65, which is precisely the working population a plan is usually built around.

Maxfield, M., Greenberg, J., Pyszczynski, T., et al. · 2014 · International Journal of Aging and Human Development

Reminders of mortality increased generative concern and shifted preference toward legacies that help others rather than legacies that bring recognition, in older adults but not younger ones. Two experiments with US undergraduates and adults aged 60 to 92, predominantly white and predominantly female; the two age groups did not differ without the mortality prime.

Human Wealth™ Synthesis · Generativity is what legacy planning is actually for. It frames estate work as the client's answer to what outlives them, with the tax treatment as a consequence rather than the purpose.

Dobbie, W., & Song, J. · 2014 · NBER Working Paper 20520

Exploiting the random assignment of bankruptcy filings to judges across 500,000 Chapter 13 filings matched to administrative tax and foreclosure data, Chapter 13 protection increases annual earnings. The authors state these results come primarily from the deterioration of outcomes among dismissed filers rather than gains by granted filers.

Human Wealth™ Synthesis · A rare causal design on a financial intervention, and its second sentence is the one to carry. The effect is measured against what happens to people refused protection, so the finding is about the cost of losing a buffer rather than the benefit of gaining one, and a chapter that reports only the headline would invert its meaning.

Fernandes, D., Lynch, J. G., & Netemeyer, R. G. · 2014 · SSRN Working Paper 2333898

Interventions to improve financial literacy explain only 0.1% of the variance in the financial behaviors studied, with weaker effects in low-income samples.

Human Wealth™ Synthesis · The small-effects spine of the corpus, and the counterweight to Kaiser and colleagues. The pair is the reason this issue argues from mechanism rather than from programme efficacy: when two meta-analyses of the same question disagree, the defensible claim is about how a service acts, not about what it achieves.

Carver, C. S., & Scheier, M. F. · 2014 · Trends in Cognitive Sciences 18(6):293-299

Optimism is a cognitive construct concerning expectancies about future outcomes that also relates to motivation, in that optimistic people exert effort where pessimists disengage. The authors note that studies aimed at settling whether optimism is best viewed as unidimensional have reached opposite conclusions.

Human Wealth™ Synthesis · The theoretical basis for ELEMENT_03, and it arrives with its own unsettled measurement question. We record the disagreement rather than picking the reading that suits a scale, because how a construct is measured is what our own indices ultimately inherit.

Lusardi, A., & Mitchell, O. S. · 2014 · Journal of Economic Literature 52(1):5-44

The canonical review of the economics of financial literacy. It casts financial knowledge as a form of investment in human capital, notes that establishing a causal link between literacy and economic behaviour is challenging, and observes that despite the popularity of financial education programmes only a few authors have undertaken careful evaluations. It states that some population subgroups optimally have low financial literacy, particularly those anticipating substantial safety net income in old age.

Human Wealth™ Synthesis · The source that reframes ELEMENT_05 away from a deficit model. If low financial literacy can be an optimal allocation of attention for some households, then capability is not a gap to be closed in everyone, and any education claim in this issue has to say for whom.

Mani, A., Mullainathan, S., Shafir, E., & Zhao, J. · 2013 · Science

Inducing financial concerns impairs fluid intelligence and cognitive control, an effect the authors calibrate as comparable to losing a full night of sleep, or about 13 IQ points. Shown in New Jersey mall shoppers and in Indian sugarcane farmers measured before and after harvest.

Human Wealth™ Synthesis · We operationalize cognitive friction as the Bandwidth Tax (MET_BW_TAX). The bridge this paper licenses is its own policy sentence about cognitive taxes: long forms, lengthy interviews, deciphering rules. Note the direction of the evidence, which is about people under financial strain rather than about the wealthy, and the term Bandwidth Tax is ours and Mullainathan and Shafir's, not this paper's.

Clark, A. E., & Georgellis, Y. · 2013 · Economica

Across eighteen waves of British panel data, adaptation of life satisfaction to marriage is rapid and complete, as it is to divorce, childbirth and widowhood. Adaptation to unemployment is not. The pattern held on both a single-item life satisfaction measure and a twelve-item scale, and replicated earlier German panel findings. One exception is reported: for women after widowhood, on the GHQ-12, around 10 to 15 percent of the initial effect persists two or more years on.

Human Wealth™ Synthesis · Anchors Marriage or Partnership (TRANS_07) as a Wellbeing-lens transition and speaks to Satisfying Life (ELEMENT_14). The marriage signature is a spike and return in evaluative wellbeing rather than a permanent lift, which locates the durable value of the transition in the activated Resources elements, Social Network (ELEMENT_08) and Financial Security (ELEMENT_06), rather than in lasting satisfaction.

Bonanno, G. A., & Diminich, E. D. · 2013 · Journal of Child Psychology and Psychiatry 54(4):378-401

Introduces the terms emergent resilience and minimal-impact resilience to distinguish two trajectories of positive adjustment, and argues that because of the wide range of outcomes they evoke, such events are more appropriately described as potentially traumatic events.

Human Wealth™ Synthesis · The distinction that stops resilience being one thing: holding steady through an event and rebuilding after one are different trajectories with different requirements. It is the conceptual basis for treating MET_AQ as describing a path rather than a score.

Bonsang, E., Adam, S., & Perelman, S. · 2012 · Journal of Health Economics

Using social security eligibility age as an instrument in US Health and Retirement Study data, retirement causes a fall in episodic memory of close to 10 percent. The effect arrives with a lag and is concentrated at the beginning of retirement, stabilising afterwards rather than compounding.

Human Wealth™ Synthesis · TRANS_08 (Retirement) cannot just be a cessation of labor, and the evidence sharpens where the risk sits: the damage is front-loaded, so the window that matters is the transition itself rather than the whole of retirement. The Third Act Index (MET_TAI) should weight the first years accordingly.

Berman, M. G., Kross, E., Krpan, K. M., Askren, M. K., et al. · 2012 · Journal of Affective Disorders 140(3):300-305

Participants showed significant increases in memory span after a nature walk relative to an urban walk. The authors note it was unclear whether the same benefits would be achieved in a depressed sample, since walking alone in nature might induce rumination and thereby worsen memory and mood.

Human Wealth™ Synthesis · A rare manipulation in a literature that is mostly observational, which is why it carries weight out of proportion to its size. Its caution is the more useful half for practice: the same intervention meets a different Composition and does something different, so an environmental prescription is not general.

Rick, S. I., Small, D. A., & Finkel, E. J. · 2011 · Journal of Marketing Research 48(2):228-237

Tightwads generally spend less than they would ideally like and spendthrifts more, and people tend to marry their opposite. That complementary attraction seems bad for marriages: the degree to which spouses differ predicts conflict over finances, which in turn predicts diminished marital wellbeing. The authors flag that absolute difference scores are confounded with their components.

Human Wealth™ Synthesis · The evidence behind treating financial friction between partners as its own quantity. Its stated limitation is a direct constraint on MET_CF, which is built from absolute differences across Elements, and the metric has to answer the objection its own source raises.

Holt-Lunstad, J., Smith, T. B., & Layton, J. B. · 2010 · PLoS Medicine 7(7):e1000316

Across 148 studies and 308,849 participants, people with stronger social relationships had a 50% increased likelihood of survival (OR = 1.50, 95% CI 1.42 to 1.59). The authors place the magnitude alongside well-established mortality risk factors such as smoking and alcohol consumption. The effect depends heavily on how connection is measured: complex measures of social integration reach OR = 1.91, while a binary living-alone indicator falls to 1.19 and loses significance.

Human Wealth™ Synthesis · The largest evidence base in the corpus, and the clearest case that an Element reaches all the way to survival. Its measurement clause disciplines how ELEMENT_08 may be read: a single crude indicator of who you live with is not the same construct as social integration, and our own instruments should follow the complex measures rather than the binary one.

Kahneman, D., & Deaton, A. · 2010 · PNAS 107(38):16489-16493

Emotional wellbeing rises with log income but shows no further progress beyond roughly $75,000 a year, while life evaluation continues to rise. The authors describe this as a qualitative difference between the two measures: the former satiates with high income, the latter does not. They add a constraint the literature routinely drops, that their data speak only to differences between people and not to what a change in income would do to any individual.

Human Wealth™ Synthesis · The paper that makes ELEMENT_16 necessary as an Element separate from Satisfying Life, since the two measures answer to money differently. Its changes-versus-differences caveat is the sentence that must travel with any planning use of the figures: a cross-sectional comparison is not a forecast for one household.

Porges, S. W. · 2009 · Cleveland Clinic Journal of Medicine

Polyvagal theory proposes that the nervous system continuously evaluates risk without conscious awareness (neuroception), and that the defensive states it recruits are incompatible with social behaviour, social communication and visceral homeostasis. A theoretical review with no sample, no design and no effect size.

Human Wealth™ Synthesis · The theoretical underpinning of the Vitality Gate Rule, and it is a claim about the meeting rather than about the arithmetic: the theory predicts that states of mobilization compromise the ability to detect positive social cues, and that defensive states are incompatible with social engagement. An advisory conversation is social engagement. A planning claim needs a different source.

Bonanno, G. A. · 2008 · Psychological Trauma: Theory, Research, Practice, and Policy S(1):101-113

Argues that resilience is a distinct trajectory from recovery and more common after loss than had been assumed. The paper is explicit that much of psychology's knowledge about how adults cope with loss came from people who sought treatment or exhibited great distress, which is a selection problem, and it defines the comparison class as threshold psychopathology sustained over months.

Human Wealth™ Synthesis · The founding statement of the resilience trajectory literature that MET_AQ descends from, held in the corpus alongside the replication that disputes its base rates. The sampling critique it makes of its own field is the same critique the corpus applies to itself: what you conclude depends on who you looked at.

Chetty, R. · 2008 · Journal of Political Economy 116(2):173-234

Sixty percent of the increase in unemployment durations caused by unemployment insurance benefits is due to a liquidity effect rather than moral hazard. Increases in benefits have much larger effects on durations for liquidity-constrained households, identified through two separate empirical strategies within the same paper.

Human Wealth™ Synthesis · The causally identified mechanism the objective half of MET_AQ rests on, and it reframes what money does at a shock. Liquidity widens the set of options a person can choose from rather than determining the outcome they reach, which is why the index treats runway as a determinant of the option set and not as a predictor of recovery.

Eby, L. T., Allen, T. D., Evans, S. C., Ng, T., et al. · 2008 · Journal of Vocational Behavior 72(2):254-267

Mentoring is associated with a wide range of favourable behavioural, attitudinal, health-related, relational and motivational outcomes, and consistent with more focused reviews the overall magnitude of association is small.
