Definition
The psychological capacity to remain functional, thoughtful and effective in conditions of uncertainty - without prematurely collapsing ambiguity into false certainty or becoming paralyzed. Low uncertainty tolerance drives closure-seeking: rapid commitment to a position to end the discomfort of not knowing. High uncertainty tolerance enables more accurate reasoning, better decision-making under ambiguity and more successful operation in complex environments. Related to but distinct from ambiguity tolerance, which concerns structural ambiguity rather than outcome uncertainty.
When it shows up
Ambiguous situations: medical tests with unclear results, relationship uncertainty, career decisions without clear right answer. Moments when you want a definitive answer and don't have one.
Failure mode
Low tolerance produces premature closure: choosing an answer, any answer, to end the discomfort. The answer is often worse than continued uncertainty would have been.
Countermeasure
Practice sitting with 'I don't know.' The discomfort decreases with practice. Premature closure is often worse than extended uncertainty; the mind's urge to resolve is not tracking decision quality.
