Strategies for disrupting unwanted automatic behaviors.
What the evidence says
- Wood advises increasing friction for bad habits and decreasing it for good ones[1]
- Wood argues that habits and conscious decision-making run in different systems, and that this is why habits persist when self-control fails — her argument; the evidenced version is the double-edged-sword bullet below[1],[2]
- Wood’s central practical claim: environment design does more work than motivation[1]
- Stable contexts are key — change context to break cue-behavior link[3]
- When you can’t change the context, vigilant monitoring works: actively thinking “don’t do it” and watching for slipups[4]
- Avoiding triggers (stimulus control) works for temptations but not for strong habits[4]
- Monitoring strengthens your ability to inhibit the habitual response; it doesn’t erase the habit memory itself[4]
- Context disruption empirically confirmed: students transferring to a new university maintained strong habits only when performance contexts stayed stable; when contexts changed, strong habits came under intentional control[2]
- Informational interventions (persuasive messages) change intentions but have limited effect on habitual behaviors — changing minds does not necessarily mean changing behavior[2]
- Habits as a double-edged sword: after a two-day nondominant-hand self-control task, participants maintained both good and bad habits but were less likely to perform non-habitual behaviours.[2]
- Implementation intentions (if-then plans) can override habitual responses by pre-committing to a new behavior when the habitual cue arises — the if-then format creates strategic automaticity that competes with the unwanted habit[5]
