Money: saving, investing and big decisions
Financial security comes more from what people do than what they know, with behaviour and psychology doing most of the work.
Covers: This page covers the evidence on behaviors and decisions that contribute to financial security, such as saving habits, investment strategies, homeownership versus renting, and psychological factors. It does not provide personalized financial advice or specific investment recommendations.

The short answer
Interpretation AI-prepared starting mapFinancial security is shaped less by what people know than by what they do. Across the studies available, behavioural and psychological pathways carry most of the weight: financial well-being improves mainly through behavioural adjustments rather than direct exposure to technology or information, and psychological capital (resilience, hope, self-efficacy) is linked to well-being both directly and through financial behaviour. Financial education that only builds declarative knowledge has been shown to have minimal impact on behaviour, while more flexible forms of knowledge make desired behaviour change more likely. Context matters too: in one Ghanaian study, land acquisition was prioritised over financial instruments because of eroded trust in banks, and cultural norms of wealth secrecy complicated planning.1234

In brief
Behaviour, not knowledge alone, is the main lever: financial education focused on declarative knowledge has been shown to have minimal impact on behaviour, while more flexible knowledge makes behaviour change more likely.2
Evidence-backedPsychological factors matter: psychological capital was linked to financial well-being both directly (β = 0.563) and through financial behaviour (β = 0.081) in a cross-sectional study in China.3
Evidence-backedAccess and trust shape saving: a 30-month micro-savings programme in Uganda improved bank saving behaviour, but the authors stress that institutional barriers and financial literacy training must also be addressed.5
Evidence-backedWhere trust in banks is eroded, people may prefer land and other assets over financial instruments, as found among local government employees in North-Western Ghana.4
Evidence-backedTechnology can influence financial behaviour — AI had a stronger effect than family socialisation in one model — but its effect on well-being runs mainly through behaviour, with financial literacy and digital trust playing modest moderating roles.1

What it means for you
Which fits you?
Pick the situation closest to yours. Each answer says what it rests on.
If you are designing a financial education programme
focus on flexible, applied knowledge rather than declarative facts alone, since explicit-learning approaches have shown minimal impact on behaviour while more flexible knowledge made behaviour change more likely.2
Evidence-backedIf you want to build financial security but find information alone isn't changing your habits
treat behaviour and psychological factors as the target: psychological capital (resilience, hope, self-efficacy) was linked to financial well-being directly and through financial behaviour, so resilience- and self-efficacy-building may be worth pairing with financial learning.3
Evidence-backedIf you live in a low-income household and formal saving feels out of reach
the Ugandan micro-savings experience suggests saving through an account is possible when the infrastructure is brought to you and financial literacy support is provided, though institutional barriers still need addressing.5
Evidence-backedIf you distrust banks or live where banking feels unreliable
people in that situation have prioritised land acquisition over financial instruments, so consider what assets you can hold and verify locally rather than assuming formal financial products are the only route.4
Evidence-backedIf you are relying on an AI tool or app for money decisions
expect it to shape your behaviour more than your well-being directly, and note that financial literacy and digital trust modestly strengthen its effect on behaviour.1
Evidence-backedIf you are planning for retirement and keep postponing it
the Ghanaian study found high awareness but age-related postponement and inadequate preparedness, with workplace retirement education often absent — so look for planning support outside the workplace if none is offered.4

Behaviour and psychology carry more weight than knowledge alone
AI summary:Studies suggest behaviour and psychological factors drive financial well-being more than knowledge or technology alone.
Evidence-backed: A study integrating financial socialisation, technology and financial capability found that artificial intelligence exerts a stronger influence on financial behaviour than family financial socialisation, but that its impact on financial well-being operates primarily through behavioural pathways. Financial literacy and digital trust strengthened the effect of AI on financial behaviour, though those moderating effects were relatively modest. The authors conclude that improvements in well-being are largely driven by behavioural adjustments rather than direct technological exposure.1
Evidence-backed: A cross-sectional study in China found psychological capital influenced financial well-being (β = 0.563, p < 0.05) and that financial behaviour mediated part of this relationship (β = 0.081, p < 0.05), with results consistent across gender, education and age groups. The authors suggest that embedding resilience-building, hope-enhancing and self-efficacy-strengthening components in financial education may help people build more secure long-term outcomes.3
Evidence-backed: A randomised controlled trial over several sessions tested whether more flexible forms of knowledge change personal finance behaviour. As knowledge became more flexible, desired changes in actual behaviour became more likely. The authors argue that life-skills and collegiate financial education programmes may be 'barking up the wrong tree' by focusing on explicit, declarative learning, which has been shown to have minimal impact on behaviour.2

Saving depends on access and trust, not just willingness
AI summary:Savings programmes can help, but access to banking and trust in institutions shape whether people save.
Evidence-backed: A micro-savings programme adapted for Uganda followed 690 participants who opened children's development accounts, tracking self-reported and administrative savings outcomes over 30 months. The intervention improved bank saving behaviour, with a significant intervention-by-time interaction [χ2(2) = 43.38, p < 0.05]. The authors conclude that families in low-income households can use savings infrastructure when given the opportunity, but that institutional barriers must be addressed — bringing bank services to people and providing financial literacy training to instil a saving culture from a young age.5
Evidence-backed: Among local government employees in North-Western Ghana, retirement planning showed high awareness but age-related postponement. Plans prioritised land acquisition over financial instruments because of eroded trust in banking institutions. Drivers of planning included personal goals, family obligations and, notably, the absence of workplace retirement education programmes. Overall preparedness was inadequate, complicated by cultural norms of wealth secrecy used as protection against envy and social obligations.4

What 'security' means in finance
AI summary:In finance, a security is a tradable financial asset, defined differently across jurisdictions.
Evidence-backed: In finance, a security is a tradable financial asset. The term commonly refers to any form of financial instrument, but its legal definition varies by jurisdiction: some jurisdictions exclude instruments other than equity and fixed income, while others include instruments close to them such as equity warrants. Securities may be certificated or, more typically, held in electronic or book-entry form, and certificates may be bearer or registered.6

- 1An integrated model of financial socialization, technology, and financial capability in predicting financial well-being.PloS one (Anh)Published Mar 24, 2026Checked Oct 4, 2026
“Artificial intelligence exerts a stronger influence on financial behaviour than family financial socialisation, while its impact on financial well-being operates primarily through behavioural pathways. Financial literacy and digital trust significantly strengthen the effect of artificial intelligence on financial behaviour, although the moderating effects are relatively modest. Financial well-being is positioned as the ultimate outcome of the model, and the findings confirm that improvements in well-being are largely driven by behavioural adjustments rather than direct technological exposure alone. The study offers theoretical contributions by integrating social, technological, and capability-based elements into a unified financial well-being framework and highlights the conditional roles of digital trust and financial literacy in shaping AI-driven financial behaviour. It also provides practical implications for financial education and responsible digital finance adoption to enhance financial resilience and long-term well-being.”
- 2The challenge of explicit learning in life skill education.NPJ science of learning (Piehlmaier & Warmath)Published Dec 1, 2025Checked Oct 4, 2026
“Curriculum design in programs to build life skills often focuses on explicit learning methods that aim to increase declarative knowledge. However, this type of education has been shown to have minimal impact on behavior. We introduce a continuum of knowledge and argue that more flexible forms of knowledge are required to impact behavior, especially for novices. Using a randomized controlled trial conducted over several sessions, this study explores the ability of semi-flexible and flexible knowledge to promote optimal behaviors in the context of personal finances. We found that as knowledge became more flexible, desired changes in actual behavior became more likely. Our results provide evidence that life skills education programs, such as collegiate financial education, may be "barking up the wrong tree" with the focus on explicit learning. Expanding program design to incorporate a focus on flexible knowledge may improve the impact of such programs on desired behavior.”
- 3The mediating role of financial behavior in the relationship between psychological capital and financial wellbeing: evidence from a cross-sectional study in China.Frontiers in psychology (Zhang et al.)Published Apr 14, 2026Checked Oct 4, 2026
“We found that Psychological Capital does indeed influence Financial wellbeing (β = 0.563, p β = 0.081, p Q 2_predict > 0.10; Standardized Root Mean Square Residual (SRMR) = 0.028; Normed Fit Index (NFI) = 0.973) and a smoothness across gender, education, and age. We also find that it is consistent across gender/education and age groups. All of these results support Psychological Capital to be a potentially flexible psychological tool that can positively affect financial wellbeing directly and in a more adaptive manner. This suggests that interventions embedding resilience-building, hope-enhancing, and self-efficacy-strengthening components within financial education may help individuals cultivate more secure long-term financial outcomes. By embedding Psychological Capital within a behavioral explanation framework, we complement the model of financial well-being and provide one of the first population-weighted PLS-SEM studies on the relationships between Psychological Capital and Financial Behavior in China.”

“Data were analyzed using thematic analysis, guided by the life course perspective and theory of planned behavior.FindingsKey findings include (1) thoughts on retirement indicated that there was high awareness but age-related postponement of planning; (2) retirement aspirations were guided by financial security, homeownership, healthcare access, and family time; (3) content of retirement plans included land acquisition prioritized over financial instruments due to eroded trust in banking institutions; (4) drivers of retirement planning included personal goals, family obligations, and notably, the absence of workplace retirement education programs; (5) overall preparedness showed inadequate preparation, complicated by cultural norms of wealth secrecy as a protective strategy against envy and social obligations.ConclusionLocal government employees in Northwestern Ghana demonstrate inadequate retirement preparedness. Effective interventions require context-sensitive approaches addressing financial literacy, workplace education programs, and the cultural dynamics of savings disclosure in collectivist, resource-constrained settings.”
- 5Adapting a U.S.-based micro-savings program for Uganda: implementation process and lessons learned.Children and youth services review (Namuwonge et al.)Published Feb 3, 2026Checked Oct 4, 2026
“The analysis focused on saving behaviors among the entire sample and a subsample of 690 participants who opened CDAs. We examined self-reported and administrative savings outcomes over 30 months, encompassing bank savings behavior and savings beyond the initial deposit. Analyses also addressed key sociodemographic and psychosocial factors. A mixed-effect and adjusted logistic regression model were applied.ResultsAt enrollment, the participant's mean age was 15.37 years. The intervention improved bank saving behavior, evidenced by significant intervention-by-time interaction effects [χ2(2) = 43.38, p Conclusions and implicationsThese findings suggest that, overall, CDA-based micro-saving programs implementation is possible even in resource limited communities like Uganda, and when given the opportunity, families living in low-income households can utilize the CDA "infrastructure" to save. Overall, for the saving intervention to yield its intended benefits, institutional barriers need to be addressed, including bringing the bank services to the people and providing financial literacy training to instill the culture of saving from a young age.”
- 6Security (finance) (Wikipedia)WikipediaPublished Sep 30, 2026Checked Oct 4, 2026
“A security is a tradable financial asset. The term commonly refers to any form of financial instrument, but its legal definition varies by jurisdiction. In some countries and languages people commonly use the term "security" to refer to any form of financial instrument, even though the underlying legal and regulatory regime may not have such a broad definition. In some jurisdictions the term specifically excludes financial instruments other than equity and fixed income instruments. In some jurisdictions it includes some instruments that are close to equities and fixed income, e.g., equity warrants. Securities may be represented by a certificate or, more typically, they may be "non-certificated", that is in electronic (dematerialized) or "book entry only" form. Certificates may be bearer, meaning they entitle the holder to rights under the security merely by holding the security, or registered, meaning they entitle the holder to rights only if they appear on a security register maintained by the issuer or an intermediary.”
