To optimize mental health and motivation, it is recommended to structure rewards (dopamine) using variable and unpredictable delays rather than constant ones.

This advice is based on the principles of operant conditioning, initially explored by B.F. Skinner, who demonstrated that variable-ratio reinforcement schedules (where the reward occurs unpredictably) induce more persistent behavior than fixed reinforcement. Neuroscience research, notably studies on the dopaminergic system in primates (e.g., the work of Wolfram Schultz), confirms that dopamine responds not only to rewards but primarily to reward prediction error (the unexpected). While the biological basis is solid, the direct application to daily well-being remains a behavioral extrapolation. The idea is that constant predictability decreases engagement, whereas uncertainty maintains interest. There is no specific clinical meta-analysis on the self-application of this technique for mental health, but the mechanisms of motivation are well-documented in psychological literature. The risk is exaggeration: it is not a miracle solution, but one lever among others for regulating engagement.
