Implementation Intentions
Deciding when and where you'll act makes follow-through 65% more likely.

The Principle
An implementation intention is a specific if-then plan: "At [time], in [place], I will [action]." Instead of relying on motivation, you pre-decide exactly when and how you'll act, which lets your brain trigger the behavior almost automatically when the moment arrives.

Key Statistic
People with if-then plans are d = 0.65 more likely to achieve goals (94 studies, 8,000+ participants) [1]
What The Research Shows
Gollwitzer & Sheeran (2006) conducted a meta-analysis of 94 studies (N > 8,000) and found a medium-to-large effect of d = 0.65 for if-then plans on goal attainment [1]. A more recent meta-analysis by Sheeran, Listrom & Gollwitzer (2025) across 642 independent tests found d = 0.66 for behavioral outcomes and d = 0.42 for cognitive outcomes, with effects stronger when plans used explicit if-then format and were mentally rehearsed [2]. Effects are robust across health, academic, and professional domains. Limitation: high heterogeneity across studies and possible publication bias.

Common Myths
Myth: 'Just set a goal and stay motivated.' Reality: Motivation fades; specifying when, where, and how you'll act is far more effective than relying on willpower alone [1].

How Aftertone Applies This
When you create a time block in Aftertone, the app prompts you to write the specific first action you'll take (e.g., 'Open the draft and write the intro paragraph'). This transforms a vague calendar entry into an implementation intention. The if-then prompt is built into the block creation flow, not hidden in settings.
