HOW IT WORKS: Memorable highs or lows and the final impression dominate user recollection. Designers can strategically place positive experiences and ensure the conclusion is satisfying.

IN UX/UI/AI DESIGN: UX, UI, and AIX designers highlight moments of delight and make task completion smooth and satisfying. AI can identify key interaction points and optimize the experience to leave a strong positive final impression.


EXAMPLE: An app shows celebratory animations upon completing a task. A GenAI workflow ensures that final summaries or results are visually clear, rewarding, and memorable.

The Peak-End Rule, identified by Daniel Kahneman in the 1990s, shows that users evaluate experiences based on the most intense moments and the final outcome, rather than the average experience. This principle comes from cognitive psychology and behavioral economics.
