What is Trigger-action plan?
A trigger-action plan (TAP) is a specific if-then rule that links a situational cue (trigger) to a concrete behavior (action). It is the practical implementation format for Gollwitzer’s implementation intentions research, designed to automate good decisions by pre-programming responses to predictable situations.
How it works
The format is simple: ‘When [specific situation], I will [specific action].’ Research shows that TAPs roughly double the likelihood of following through on goals compared to mere goal intentions. They work by delegating the initiation of behavior from deliberate decision-making to automatic cue detection: when the specified situation is encountered, the planned action is triggered without requiring willpower or deliberation. Effective TAPs use vivid, specific triggers and single, concrete actions.
Applied example
Instead of ‘I will exercise more,’ a trigger-action plan specifies: ‘When I park my car after work, I will put on my running shoes and walk for 20 minutes before going inside.’ The trigger (parking the car) is specific and unavoidable, and the action (put on shoes and walk) is concrete and immediately executable.
Why it matters
Trigger-action plans are one of the most evidence-backed individual behavior change tools because they harness the brain’s automatic cue-response system, making good decisions effortless rather than effortful.
