You feel a frantic urge to act during uncertainty.

In a study of professional soccer penalty kicks, goalkeepers were statistically more likely to dive left or right than to stay in the center, despite staying still yielding better outcomes.

This is the action bias: in high-stakes environments, the brain views movement as a more 'rational' response than stillness. Doing nothing feels like passivity, so you choose an action, even if it is counterproductive.
