🎯 Implementation Intention Builder — Gollwitzer 'When-Then' Format
Peter Gollwitzer's research: specific 'When X, then I will Y at Z' statements boost completion rate 40-80% vs. vague 'I'll try to X.' The simplest…
Why this is epic
Gollwitzer's meta-analysis (94 studies, 8,000+ participants): implementation intentions vs. vague goals produce 40-80% higher follow-through. Simple linguistic structure makes the difference.
Format: 'When [specific situation], then I will [specific behavior] at [specific location].' Versus: 'I'll exercise more.' Three specificities transform intention into near-automatic behavior.
Works for short-term goals (one-time tasks) AND habit formation. Highest-leverage simple tool in behavior change research.
The prompt
Example: input → output
Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.
<goal>Write my book — 500 words per day</goal> <typical-obstacle>Morning gets hijacked by email / kids / work urgency. Then it's 11am and I haven't written and I tell myself 'I'll do it tonight' and tonight I'm exhausted and skip.</typical-obstacle> <context>Work-from-home father, 2 kids, consulting job</context>
Your Implementation Intention
When my coffee finishes brewing at 6:15am (before kids wake, before email), then I will sit at my kitchen table with laptop closed to all browser tabs, open the book document, and write 500 words before checking anything else.
Specifics:
- WHEN: 6:15am coffee-brew completion (specific time + anchor)
- WHAT: write 500 words with laptop-closed-to-distractions
- WHERE: kitchen table (not office — different context, different associations)
- Bounded by: before kids wake + before email (time + attention-protection)
Contingency If-Then
If the kids wake before 6:15am (sometimes happens), then I will write for 20 minutes instead of 500 words — whatever I can produce.
If I'm traveling / not home, then I will write 500 words at hotel/location while drinking morning coffee.
If I oversleep and it's 7am, then I will skip writing today (not try to catch up) and resume tomorrow.
Contingency prevents catastrophic-thinking ('I missed, might as well skip a week').
Triple-Encoding Instructions
1. Write it: post-it note on coffee machine: '6:15am → 500 words kitchen table.'
2. Say it aloud once per day for first week: morning when you see the post-it, say the full intention out loud.
3. Post it visible: the coffee-machine post-it. Also on laptop screen when laptop is in kitchen.
Triple-encoding boosts follow-through significantly in research.
If It Fails
Diagnostic questions:
- Is 6:15am actually a moment you're alert + available? If not, shift time.
- Is 'kitchen table' location triggering distraction (near email setup)? Try bedroom desk instead.
- Is 500 words too ambitious for your current writing muscle? Drop to 250 for 30 days.
- Is coffee-brew reliable as anchor? If you sometimes skip coffee, different anchor needed.
One variable per adjustment cycle. Don't change all three at once.
Common use cases
- Setting up new habit with research-validated structure
- One-time tasks you keep forgetting (paperwork, calls, appointments)
- Gym/exercise commitments
- Social commitments (calling mom, catching up with friend)
- Work tasks you procrastinate on

Pro tips
- Three specifics matter: WHEN, WHERE, WHAT. Missing any = weaker effect.
- Specificity over optimism. 'Tuesday 7am at home gym' > 'mornings.'
- Write it. Say it aloud. Post it visible. Triple-encoding boosts follow-through.
- One intention at a time. Three simultaneous = research-validated effect diminishes.
- If intention keeps failing, the 'when' isn't specific enough.
Customization tips
- For people who struggle with 'when' precision: go even more specific. Not 'morning' — '7am Tuesday.' Not 'before work' — 'after I finish breakfast.'
- For predictably-disrupted schedules (shift work, travel-heavy): intention is tied to event not clock. 'When I finish my first meeting of the day, then...'
- For avoidance behaviors: add 'even if I don't feel like it' to intention. Research-validated reinforcement.
- For team / family intentions: shared implementation intentions work. 'When it's Sunday evening, we will meal-prep for the week together at the kitchen.'
- For ADHD adaptation: intention + external reminder combined. Phone alarm PLUS post-it PLUS calendar block. Multiple scaffolds.
