Recency Illusion
Updated 2026-08-01
INTRODUCTION
English translation pending.
CORE DEFINITION
A cognitive bias described by linguist Arnold Zwicky, in which people judge a usage as recent because it entered their own awareness recently, even though it has existed for decades. It is driven by selective attention and availability: once you notice a pattern you see it everywhere, and you misread your own noticing as the pattern's arrival. The qualifier is that the illusion concerns the observer's awareness, not the age of the phenomenon.
SCAFFOLDING EFFECT
Reduce cognitive load
- Trend triage: pause before calling a phenomenon new, and ask when it actually started. - History check: trace the lineage of a market or technology shift before judging it. - Baseline building: keep dated records so your sense of change stays anchored to evidence.
Anchor fast decisions
Attention is selective, so a pattern becomes visible only after something makes it salient. Once it is salient, every instance is encoded and recalled, which produces a sharp rise in perceived frequency with no change in the world. Because perceived frequency is used as evidence of novelty, the observer's own noticing is mistaken for the phenomenon's birth.
