Framing effect

Origin: Tversky & Kahneman, 1981

Biological Parallel

Bees presented with 60% sugar solution avoid it when framed as '40% water' but accept it when framed as '60% sugar'—identical nectar, different frame. Survival depends on rapid pattern recognition, not statistical analysis, so brains evolved to react to framing cues. Predators 'hunt successfully 30% of the time' sounds different from 'fail 70% of hunts,' yet it's the same data. Framing isn't deception; it's exploiting how evolved perception shortcuts statistical reasoning.
