Buridan's Ass
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
A perfectly rational donkey stands between two identical piles of hay at equal distances. Because it cannot find a rational reason to prefer one over the other, it eventually starves to death due to indecision. -
SCAFFOLDING EFFECT
Reduce cognitive load
A method to break decision paralysis. - When two options are extremely close in value, further thinking (rational comparison) is redundant and harmful. At this point, the optimal solution is not to continue analyzing but to introduce "randomness" (like flipping a coin) or "intuition" to get moving. Starving between two piles of hay is the greatest tragedy of rationality.
Anchor fast decisions
Buridan's ass (and the Buridan effect) refers to a thought experiment by medieval philosopher Jean Buridan to illustrate that "perfect equilibrium leads to inability to choose": a perfectly rational donkey, placed equidistant and equal quality between two piles of hay, starves because it has no preference. It reveals that when options are equivalent and there is no basis for decision, rationality itself leads to stagnation.
