Let’s start with a hypothetical example. But first, let’s take a moment to better understand the foundations of behavioral economics. Direct the rider | The rider is the rational part of our brains, and uses data and evidence to rationalize a decision.

Prospect theory has two stages: an editing stage and an evaluation stage. David Gal has argued that many of these issues stem from behavioral economics being too concerned with understanding how behavior deviates from standard economic models rather than with understanding why people behave the way they do.
