INTRODUCTION

English translation pending.

CORE DEFINITION

A memory bias studied in survey research, where respondents systematically date events incorrectly. Forward telescoping pulls a distant event forward so it feels recent; backward telescoping pushes a recent event back so it feels remote. It distorts retrospective reports and is a known source of error in self-reported behaviour surveys. A related usage extends the metaphor to psychological distance, where remote problems are scaled down and overlooked. The qualifier is that subjective time is a reconstruction, not a record.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Timeline correction: verify remembered dates against calendars and logs before you rely on them. - Distant-risk restoration: pull far-off problems closer so they carry their true weight. - Retrospective caution: distrust recalled frequency and timing in reviews and surveys.

Anchor fast decisions

Memories are stored with weak or reconstructed temporal tags, so events are dated by their felt vividness and by landmarks rather than by a reliable timestamp. Vivid distant events feel closer, and unremarkable recent ones feel older. The same scaling applies to psychological distance, where what is far away is compressed in significance until something makes it salient.

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.
