CORE DEFINITION

Strategy evolution: strategies are not chosen but evolved. Fitness payoff: the "benefit" of a strategy is reproductive success. Evolutionarily stable strategy (ESS): a strategy that, once established, cannot be invaded.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Use an evolutionary perspective to understand strategic behavior. It is not "rational choice" but "which strategies survive in evolution"—explaining animal behavior and social norms. (Related concepts: evolutionarily stable strategy, evolutionarily stable strategy comparison, evolutionary game)

anchor

Anchor fast decisions

Treat game strategies as population traits that can be replicated, mutated, and selected. Replace rational optimization with fitness (reproductive success) to study the dynamic evolution and stability of strategies in a population over time.

Semelparity

Semelparity and iteroparity are two reproductive strategies available to living organisms. A species is semelparous if it is characterized by a single reproductive episode before death, and iteroparous if it is characterized by multiple reproductive cycles.
