Need for Certainty
People seek predictable outcomes and avoid ambiguous or unpredictable situations.
Why it works
Based on uncertainty reduction theory (Berger & Bradac, 1982), ambiguity creates cognitive stress that people are motivated to resolve. Predictable outcomes reduce anxiety by allowing mental preparation and control. The brain defaults to certainty-seeking because known risks are easier to manage than unknown ones (Ellsberg, 1961).
