🏔️ Peak-End Rule:
We remember an experience by its peaks and how it ended.
People tend to overvalue both the peak of an experience, and the end.
i.e., if you are reviewing a theatre show, you'll disproportionately associate value to both the best/worst bits (peaks), and the very end of the performance.
✅ Sharing & referrals
People are more likely to refer your product, if they've just experienced a peak (in value), or if the end of the process was particularly easy.
e.g., "you should sign up to BeepBoop, the form is pretty easy" — this is likely influenced by how "easy" the end of the process was, not an evaluation of the entire thing.
✅ Perception of value
The peak-end rule defines how people perceive value (through peaks, and remembering value over time).
