INTRODUCTION

English translation pending.

CORE DEFINITION

A memory bias documented in studies of affective forecasting and retrospective evaluation. People rate past experiences, such as holidays and projects, more favorably in retrospect than they did while the events were occurring. The reconstruction emphasizes peak moments and endings while dropping the tedious and unpleasant stretches. The bias affects how people evaluate products, workplaces, and life periods, and it diverges systematically from contemporaneous reports.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Compare with records: check retrospective ratings against what was written at the time - Read live data: weight in-the-moment reports over remembered ones when evaluating an experience - Expect the filter: assume that any account of the past has had its dull and painful parts removed

Anchor fast decisions

Memory does not store experiences whole but reconstructs them from salient fragments, and positive material is weighted more heavily in the reconstruction. Peak moments and endings are the best retained, while routine discomfort leaves little trace. Because the reconstruction is experienced as a memory rather than as a construction, the resulting evaluation feels accurate.

The Forgetting Curve

The Forgetting Curve is a curve used to describe the rate of forgetting in long-term memory. It was first proposed by psychologist Hermann Ebbinghaus based on his experiments conducted from 1880 to 1885. In these experiments, Ebbinghaus used meaningless letter combinations. By memorizing these combinations and checking the forgetting rate after a series of time intervals, he obtained this curve. Therefore, this curve is also called the Ebbinghaus Forgetting Curve.

Baader-Meinhof Phenomenon

The frequency illusion (also known as the Baader–Meinhof phenomenon or Red Car Theory) is a cognitive bias in which a person notices a specific concept, word, or product more frequently after recently becoming aware of it. The name "Baader–Meinhof phenomenon" was coined in 1994 by Terry Mullen in a …
