The Peak-End Rule: what this star will be

We remember the peak and the ending, not the length.

By Constellate · 9 September 2026 · the short form

The Peak-End Rule is a star on the Constellate sky: placed by meaning, named, and connected to the stars around it. This is the short form of its post: the line it carries, the area we colour Psychology, and what stands beside it today.

The line it carries on the sky: We remember the peak and the ending, not the length.

What stands beside it

The stars nearest to it are The Availability Heuristic, Hedonic Adaptation, Hindsight Bias and Hyperbolic Discounting, and The Availability Heuristic and Narrative Identity are already open to walk. When The Peak-End Rule opens, the conversation will land it among them, with a line drawn to each idea it touches.
