The Peter Attia Drive

NOTE

The power of persistence is fueled by the promise of unpredictability.

The distinction between variable and fixed reinforcement schedules profoundly influences behavior and persistence. In a fixed reinforcement schedule, where rewards are predictable—either by time or number of actions—the cessation of rewards leads to quick extinction of the behavior, as individuals lose motivation upon realizing no reward is forthcoming. In contrast, variable reinforcement schedules, especially variable ratio schedules, sustain persistence despite the unpredictability of rewards. This model showcases why individuals, like those at a slot machine, continue seeking rewards even in the absence of consistent returns, embodying a belief that they are 'due' for a reward. This tendency to press on, driven by hope for a forthcoming reward, exemplifies the psychological mechanisms underpinning persistence in both animals and humans.
