Your investment decisions feel rational in the moment. The research shows they rarely are. This is the scientific account of why, built on behavioural finance's most replicated findings.
If you have ever sold a winning investment too soon, held a losing one far longer than you should have, traded more than your results justified, or watched your risk appetite shift dramatically with market conditions you could not rationally explain, this book is the precise account of what was happening. These are not failures of discipline or knowledge. They are documented psychological mechanisms, measured across millions of investors, and they operate in almost everyone who participates in financial markets.
Financial Psychology is a rigorous, research-grounded account of the specific cognitive and emotional mechanisms that govern financial decision-making under risk and uncertainty. Drawing on the behavioural finance literature, including the foundational prospect theory research of Kahneman and Tversky, the individual investor studies of Odean and Barber, and the wealth accumulation research of Stanley and Fallaw, this book explains with precision why rational financial decision-making is so consistently difficult, and what the science actually shows about the gap between how investors think they are deciding and how they actually are.
What this book covers:
- Why prospect theory replaced expected utility as the dominant model of financial decision-making, and what the loss aversion coefficient of approximately 2 to 2.5 means for every investment choice you make
- How the disposition effect causes investors across populations to sell winning positions too early and hold losing ones too long, in patterns that are precisely measurable and financially costly
- Why overconfidence is the most robust and most expensive documented bias in investor psychology, and what the research shows about the inverse relationship between perceived skill and actual investment performance
- Why risk tolerance is not a stable personality trait that can be measured once and applied to allocation decisions, but a state-dependent assessment that shifts with recent experience, emotional context, and how the question is framed
- How anchoring, recency bias, the availability heuristic, and confirmation bias each distort financial judgement in distinct and documented ways
- Why herding behaviour persists in financial markets even among investors who know about it, and what the research distinguishes between rational informational herding and irrational social influence
- What the Stanley and Fallaw wealth accumulation research identifies as the behavioural patterns that predict long-term wealth independent of income, and where that research's methodological limitations need to be honestly acknowledged
- What the evidence actually shows about debiasing: why knowing about a cognitive bias does not reliably reduce its effects, and what limited interventions the research does support
This is not an investment guide. It contains no asset allocations, market predictions, product recommendations, or trading strategies. It is the behavioural science account that investment advice has always assumed you already understood, written for the reader who wants the science before the prescription.
Financial Psychology is the third volume in The Money Psychology Series, a research-grounded collection applying behavioural science to the forces that shape how human beings earn, spend, save, and self-sabotage with money.
