The named slot changes everything
Peter Gollwitzer’s landmark research shows why specific when-and-where planning dramatically outperforms vague intention.
In his 1999 meta-analysis of 94 studies, psychologist Peter Gollwitzer found that people who formed specific implementation intentions — “I will do X at Y time in Z location” — were 2 to 3 times more likely to follow through than those who only set goals. The mechanism: the situation itself becomes the trigger. No willpower required. The decision is already made.
Every day: Should I go today? Is today a workout day? I’ll do it tomorrow.
Result: It doesn’t happen.
Thursday arrives: this is a workout day. The question isn’t “whether” — it’s “6pm or 7pm.”
Result: It usually happens.
