Principle
Do not call a calendar appointment an if-then plan when the action still needs preparation
'Thursday at six' is a schedule; it is not automatically a cue-response mechanism.
When it fits
- A scheduled task is labeled an implementation intention even though the trigger does not make the action executable.
When to avoid it
- Both methods can be useful; the distinction is mechanistic, not a ranking.
Why it matters
The 2026 review explicitly distinguishes strict if-then plans from broader when/where/how scheduling. Use calendars for reserving time. Use if-then plans when you want a recurring cue to trigger a ready action. Combining them is fine, but naming the mechanism correctly helps you fix the right failure.
An example
'Thursday 18:00 gym' is scheduling; 'if I close the laptop at 17:45, then I put on the prepared gym clothes' is a cue-action plan.
Check your result
Scheduling and cue-response design are used for different problems rather than conflated.
Keep this limit in mind
- Both methods can be useful; the distinction is mechanistic, not a ranking.
