Peak-End Rule
Your brain doesn’t remember the sum of an experience. It only remembers the most intense emotional peak and the exact final moments, discarding everything else.
THE TRAP TEST
1 / 5You have a brilliant 7-day vacation, but lose your passport at the airport on the way home.

The Compression of Memory
The human brain cannot store an entire video file of your life. To save energy, it compresses experiences into a single highlight reel. It grabs the loudest moment (the peak) and the final frame (the end), mashes them together, and throws the rest in the trash.
The Customer Service Death Blow
A premium airline spent millions perfecting their in-flight meals and seating. But their baggage claim process was a nightmare. Customers routinely rated the entire airline as 'terrible' because the final touchpoint (waiting 45 minutes for a bag) completely annihilated the memory of the luxury flight.
How to Engineer Memories
Over-Invest in the Finish
Stop spreading resources evenly. Backload your effort to ensure the final interaction is always spectacular.
Create Artificial Peaks
Inject one moment of extreme delight into an otherwise boring process to hijack the memory formation.
Salvage the Endings
If a project or relationship goes south, spend disproportionate energy ending it well. The end is all they will remember.
