Tolerance of uncertainty
The ability to keep acting when information is missing or the situation is ambiguous.
Tolerance of uncertainty is the ability to cope with situations whose outcome is open or that allow more than one interpretation, and to keep acting. People with high tolerance make decisions even with incomplete information. People with low tolerance seek certainty, delay decisions, or reach for premature solutions.

The ability to live with open questions and still decide.
Not indifference and not a lack of analysis. The analysis simply ends before certainty arrives.
Because leadership decisions are almost always made under uncertainty.
Origin and research
In 1949, psychologist Else Frenkel-Brunswik described intolerance of ambiguity as a personality variable. People with strong intolerance tend to force unclear situations quickly into simple categories. Once they have settled on an interpretation, they hold on to it even when new evidence points the other way.
Today, research distinguishes two related concepts: ambiguity tolerance, which concerns ambiguous information, and tolerance of uncertainty about the future. Both can change. People who repeatedly experience that decisions with open outcomes are manageable gain confidence.
For high performers
Leadership decisions rarely come with complete data. Waiting for certainty delays decisions, and faking it costs trust as soon as the situation turns. Both cost more than an openly reasoned decision with stated caveats.
A short check before every major decision helps: what do I know for sure, and how would I notice that I am wrong? That turns uncertainty into a quantity you can plan with. You decide with open eyes and can adjust course without losing face. Tell your team openly which assumption the decision rests on and when you will review it.
Distinctions
vs. Rigidity
Rigidity is often a consequence of low tolerance of uncertainty: whoever struggles with ambiguity clings to familiar patterns.
vs. Risk appetite
Risk appetite concerns the willingness to accept possible losses. Tolerance of uncertainty concerns how you handle not knowing.
vs. Psychological flexibility
Psychological flexibility is the broader concept. Tolerance of uncertainty is one of its preconditions when the situation is open.
Frequently asked questions
What is the difference between tolerance of uncertainty and ambiguity tolerance?
Ambiguity tolerance refers to information that can be read in more than one way. Tolerance of uncertainty refers to an open outcome in the future. In everyday language the two terms are often used interchangeably.
Can you learn to tolerate uncertainty?
Yes. People who repeatedly make decisions with open outcomes and review afterwards how things went increasingly experience uncertainty as manageable. It helps to define in advance how you would recognize a mistake.
Why is it so hard to decide without all the information?
Because uncertainty is experienced as a threat and triggers the need for control. More information promises safety. Often it only delays the decision without substantially improving the picture.
