behavior

Simply stating your intent makes you act more often.

The mere measurement effect suggests that asking about intentions can influence subsequent behavior, but the effect is highly contingent on the nature of the task and timing.

The effect is not a universal mechanism; it is significantly moderated by social desirability and often diminishes over time.

Your stated intentions shape your future behavior.

Confidence
Solid, with limits
