This is a Lexicon entry: the mechanism, when it shows up, and the countermeasure. The full correction, with real-world cases and the audit prompt, hasn't been written yet.
Definition
The neurological mechanism by which repeated behaviours become automatic: a cue triggers a routine, which produces a reward, which encodes the association between cue and routine. Over time, the cue alone initiates the behaviour with diminishing conscious involvement. Charles Duhigg popularized the loop framework in The Power of Habit, drawing on MIT research by Ann Graybiel. Understanding the loop enables deliberate habit modification: you can change the routine while keeping the cue and reward.
When it shows up
Any repeated behaviour: morning routines, snacking, checking phone, responding to stress. Especially behaviours you do without deciding.
Failure mode
The loop runs on cue-routine-reward without requiring deliberation. Once established, the cue triggers the routine automatically. Breaking the loop by willpower fails because the loop doesn't require will to run.
Countermeasure
Modify the cue (environment) or the reward (what you get from the routine), not the routine itself directly. Or substitute a new routine in response to the same cue. Changing the middle of the loop is hardest.
