The tendency to judge an experience based on how it felt at its most intense point and at its end, rather than the average of all moments.
From 'peak' (highest point) + 'end' + 'rule.' Described by Daniel Kahneman and colleagues.
The peak-end rule means you judge experiences by their BEST (or worst) moment and how they ended — a painful procedure with a gentle ending is remembered as less bad!
