B.F. Skinner

American psychologist and behaviorist (1904–1990). Founder of operant conditioning theory; developed the “Skinner box” to study how reinforcement schedules shape animal behavior.

Key contribution

  • Reinforcement schedules. Skinner’s experiments with rats and pigeons showed that when rewards are delivered matters as much as whether they are. He identified several schedules — fixed ratio, variable ratio, fixed interval, variable interval — and demonstrated that Variable ratio reinforcement (rewards delivered after a random number of actions) produces the most persistent, compulsive behavior. This is the schedule slot machines and loot boxes use.

Why he matters here

Variable ratio reinforcement is the engine inside Loot boxes, gacha systems, and mystery chests. The randomness of the reward, not its size, is what makes the mechanic compulsive — Skinner’s rats kept pressing levers long after fixed-reward subjects had given up.
