Peak-End Rule
People judge experiences primarily by their most intense moment and the way they end, rather than the total sum.
Why it works
Based on Kahneman's research (1993), memory emphasizes emotional peaks and endings over duration or average experience. Peak-end averaging dominates retrospective evaluation, making the most intense moment and final impression disproportionately influential. This memory bias affects satisfaction ratings and future choice behavior more than actual experience quality (Fredrickson & Kahneman, 1993).
