Protocol
Use a strict if-then plan only when the cue is observable and the action is executable
A useful if-then plan has a cue you can notice and an action you can start immediately.
When it fits
- You write vague implementation intentions such as 'if I have time, I will work on it.'
When to avoid it
- The 2026 meta-analysis tested fruit/vegetable behavior; transfer to productivity preserves the mechanism but not a guaranteed effect size.
Why it matters
A 2026 meta-analysis of strict if-then plans distinguished them from generic scheduling: the plan needs a perceivable cue, a directly actionable response and an explicit link between them. Use this structure for predictable barriers or repeated opportunities, not as decoration on every goal.
Steps
- The cue can be noticed without interpretation and the response can begin without another planning step.
An example
If the 14:00 status call ends, then I will open the error log and reconcile the two failed BPs.
Check your result
The cue can be noticed without interpretation and the response can begin without another planning step.
