Peak-End Rule

People judge an experience largely based on how they felt at its peak and at its end, rather than the total sum or average of every moment of the experience.

The scenario: Maria just spent 10 minutes completing a loan application at Meridian Bank. Every step before the final screen is identical in both versions. The little timeline strip in each demo shows the whole journey — notice how one screen at the very end recolors the memory of all ten minutes.

What's wrong here? Ten minutes of diligent form-filling ends with a case number, a vague waiting period, a threat about rejection, an ad, and a survey begging for stars. The final feeling is bureaucratic dread — and that feeling, not the perfectly fine 10 minutes before it, becomes the memory of “applying at Meridian”.

Submission recorded

Application #4471-B has been recorded. Allow 5–10 business days for processing.

Note: incomplete documentation will result in rejection. It is the applicant's responsibility to monitor the status of the application.

🔍 What changed

  • The ending was redesigned as a moment: a personal greeting, celebration, and a brief animation instead of a case-number receipt.
  • Vague waiting (“5–10 business days”, “monitor your status”) became three concrete steps with dates and one clear promise: “we'll email you by Tue, Jul 21”.
  • The threat about rejection, the cross-sell banner, and the survey popup were removed from the final screen — nothing competes with the closing feeling.
  • The timeline strips make the mechanism visible: both journeys are 95% identical, but the last frame dominates the remembered whole.

💼 Explaining it to stakeholders

“Customers don't average their experience — they remember the peak and the ending. We spent ten minutes of the customer's effort earning goodwill and then spent the final screen on a warning, an ad, and a survey. Investing one screen's worth of design in a warm, concrete ending changes how the entire application is remembered and retold — and it costs nothing operationally, because the processing time behind it is unchanged.”
