Theory 93/Habit formation/Ratio lens
Persistence Is Reward Against Effort
The claim
Habit persistence is set by the ratio of reward to effort, so a habit with high effort persists only while the reward is high.
01Mechanism
Repeated behaviour is maintained by reinforcement; the ratio determines whether the loop continues.
02Prediction
Persistence should track the ratio.
03Refutation
Persistence tracking reward alone would remove effort.
