Engineer strong endings for experiences and interactions
The last few moments of an experience have outsized influence on how it’s remembered — invest in endings.
Why it works
Memory for an experience is dominated by its peak and end; the ending is particularly controllable because it is the last available input to the memory trace. A strong ending doesn’t require the entire experience to be positive: Kahneman and Fredrickson’s colonoscopy study showed that adding a less-painful tail at the end improved retrospective ratings even though it extended total discomfort. This has direct implications for meetings, conversations, difficult sessions, and personal experiences: how something ends is the most practical lever for influencing the memory.
How to do it
- Before ending any significant experience (meeting, difficult conversation, workout, presentation), plan the last two to three minutes deliberately.
- End with something specific and positive: a clear summary, an expression of appreciation, a moment of relief or humor.
- Avoid ending with unresolved problems, complaint, or information dumps — the last thing said has outsized memory weight.
- For difficult experiences, taper rather than abrupt-stop: a few minutes of lighter content after the hardest part improves retrospective ratings.
Evidence
Redelmeier and Kahneman (1996) showed in a colonoscopy study that patients whose procedure was extended with a less-painful tail rated the overall experience as less bad, despite greater total discomfort — a direct demonstration of the ending effect. (rct)
The ending effect may be smaller for experiences with a very powerful peak, or for experiences where the person knows the ending is artificially managed — authenticity matters.

Common mistake
Spending all the design energy on the opening and middle of an experience and treating the ending as whatever happens to come last.

More practices for The Peak-End Rule — How Memory Distorts Experience
- Identify and amplify the emotional peak of an experience
The most emotionally intense moment of an experience dominates its memory — design for a peak worth remembering.
- Correct for duration neglect when estimating how much you’ll enjoy something
You’ll underestimate how much a longer good experience is worth — and overestimate the badness of a longer bad one — correct for this before deciding.
- Check whether a memory is accurate before using it as evidence
Memories of past experiences are reconstructed through peak-end, not recorded — verify important ones before acting on them.
- Savor positive peaks in real time to encode them more strongly
Attention during a positive peak strengthens its memory trace and increases retrospective satisfaction.
- Decide whether you’re optimizing for experience or for memory
For major choices, explicitly ask: "Am I choosing for who will live this — or for who will remember it?"
