A glimpse inside
Beyond Rationality: People Aren't Perfect Calculators
A central theme of the book is the challenge to classical economics' assumption that people always act rationally to maximize their self-interest. Altman explains that real-world decisions are often shaped by emotions, habits, and cognitive shortcuts, leading us to choices that deviate from what traditional models would predict. Understanding these deviations helps explain why people overspend, under-save, or make inconsistent choices.
The Power of Heuristics and Biases
The book delves into the mental shortcuts—heuristics—and systematic errors—biases—that influence our economic decisions. Examples like the anchoring effect, loss aversion, and overconfidence illustrate how these psychological tendencies can lead to suboptimal financial outcomes. Recognizing these patterns is the first step toward mitigating their negative impact.
