SCAFFOLDING EFFECT
Reduce cognitive load
Adaptive survival rule. It is more robust than complex strategies. In a changing environment, do not cling to fixed theories; adjust promptly based on feedback: repeat what works, change what doesn't.
Anchor fast decisions
"Win-stay, lose-switch" is an abbreviation for "winner stays, loser switches," meaning that after competition or evaluation, the winner maintains their position, while the loser must change or move, driving adaptation and renewal. It is similar to "winner stays, loser leaves," and its origin as a fixed term is yet to be verified.
