INTRODUCTION
English translation pending.
CORE DEFINITION
Demonstrated by Niko Tinbergen in the 1940s and 1950s. He showed that birds would abandon their own eggs to incubate larger, more vividly marked plaster dummies, and that other species respond similarly to exaggerated cues. The concept was extended to humans by Deirdre Barrett in Supernormal Stimuli, who argues that junk food, pornography and digital media act as exaggerated versions of ancestral cues. The qualifier is that the response is to the cue, not to the outcome the cue once predicted.
SCAFFOLDING EFFECT
Reduce cognitive load
- Cue identification: find the ancestral trigger that a modern product or habit exploits. - Excess detection: spot signals scaled beyond anything the environment ever produced. - Environment design: remove or throttle the exaggerated cue instead of relying on willpower.
Anchor fast decisions
Instincts operate on a small set of trigger features rather than on the real object, so the response scales with the intensity of those features. An artificial signal that exaggerates them produces a stronger response than the natural stimulus the instinct evolved for. In a modern environment full of such signals, the instinct fires at full strength with no corresponding benefit.
