Peak-End Rule

Memory of an experience is set by its most intense moment and its ending, not by its length or average; a bad hour with a good finish is remembered fondly, and designers engineer the finish.

An everyday example

A painful sales process that closes with a gift, remembered as pleasant; a great service that ends with a rude cancellation call, remembered as awful.

What it can cost you

Re-purchasing on the memory of the ending rather than the experience; being managed at the peak and the end.

Warning signs

  • The ending changed how I feel about the whole thing.
  • I do not remember the middle.

One thing to do

Log the experience as it happens; decide on the log, not on how it ended. Merged: peak-end framing strategy.
