Two-List Strategy

Biological Parallel

Foraging animals maintain mental 'accept' and 'reject' lists for food items based on energy return per handling time. Bees visiting flowers remember which species deliver nectar (approach) and which are depleted or defended (avoid). This binary classification conserves cognitive resources and eliminates time waste on marginal options. Buffett's two-list strategy applies identical prioritization: classify opportunities as pursue-now or actively-avoid, with no middle ground diluting focus.
