Financial Literacy and Its Limits
Fernandes 2014 reports that financial-literacy interventions explained about 0.1% of the variance in financial behaviours, with effects decaying over time, and suggests a narrower just-in-time role tied to specific behaviours; Miller 2015 reports effects on savings and record-keeping but not on credit default.

What the evidence says
The sources are meta-analyses, systematic reviews and cross-sectional studies of financial literacy and financial education. Fernandes 2014 (meta-analysis covering 201 prior studies) reports that interventions to improve financial literacy explained only 0.1% of the variance in financial behaviours, with weaker effects in low-income samples and decay over time, and concludes that financial education as studied has serious limitations. It suggests a narrower just-in-time role tied to specific behaviours. Kaiser 2017 (meta-analysis of 126 impact evaluations) reports that financial education affects financial behaviour and, to a larger extent, financial literacy, less so for low-income clients and in lower-income economies, with debt harder to influence, and concludes that success depends on education intensity and offering it at a teachable moment. Miller 2015 (meta-analysis of 188 papers) reports positive impact in some areas, such as savings and record-keeping, but not credit default. Aquino 2026 (systematic review) reports that literacy's impact is conditional and often negligible without self-control, and that behavioural factors frequently override financial knowledge. West 2021 (cross-sectional) reports that higher financial literacy did not reduce money-management stress or improve financial behaviour as expected, and concludes that income is more important than literacy for well-being; Utkarsh 2020 (cross-sectional) reports literacy's effect on financial well-being not significant. Other sources report literacy linked to better outcomes: Barone 2025 (systematic review) concludes that literacy is linked to lower rates of pathological gambling, though impact varies by context, and Tiwari 2025 (systematic review) reports higher literacy consistently associated with improved investment decisions. Hu 2024 (cross-sectional) concludes that financial literacy reduces mortgage stress, with high-literacy borrowers 60.3% less likely to suffer it. Among physicians and trainees, curricula were followed by improved literacy and, in some studies, behaviour change and well-being (Wesslund 2023; Igu 2022), and Cawyer 2022 reports cultivating literacy associated with an improved sense of well-being.

Each source below is shown with its study design and a link to the original study, or, where it is not a completed research paper, with what kind of record it is; those are not counted. This is the audit trail.
Why do some records show a record type instead of a study design?
A study design is shown for a completed, peer-reviewed paper. A registered protocol, a preprint, a conference abstract, a referee report or a book chapter has not been through peer review as a finished paper, so it is labelled for what it is, and it is counted in no source count. Where a record could not be confirmed as a completed paper at all, it says so rather than guessing. They all stay in the list, and their DOI still resolves, because the count of what was screened is part of the audit trail.
- Protocol / registration A registered plan for a review or trial, not its results.
- Preprint Posted by its authors before peer review.
- Conference abstract A conference summary rather than a peer-reviewed paper.
- Peer-review report A referee's report on a paper, not the paper itself.
- Guideline / position stand A recommendation derived from evidence, which is a step further from the data than the evidence itself.
- Book chapter A chapter in a scholarly book rather than a journal paper.
- Type not recorded Our record does not say what kind of publication this is, so it is counted in no source count. That is a gap in our data, not a judgement about the research.
“Abstract only” means the review read that paper’s abstract, not its full text; “screened only” means it was included at re-screening and not extracted. Both stay in the trail with their DOI, because how a source was read is part of the audit.
