🔬 The Setup
Task: Match line lengths (obviously easy)
Group: 7-9 people (only 1 real participant, rest are actors)
Procedure:
- Everyone states answer out loud
- Actors give wrong answer (unanimously)
- Real participant answers last
The question: Will they trust their eyes or conform to the group?

😱 Results
Conformity rate:
- 75% conformed at least once
- 32% conformed on average across trials
- 25% never conformed (independent thinkers)
Why people conformed:
- “I thought I was wrong”
- “I didn’t want to stand out”
- “Maybe they saw something I didn’t”

💡 Factors That Increased Conformity
Group size:
- 1 confederate: 3% conformity
- 3 confederates: 32% conformity
- 15 confederates: No further increase
Unanimity:
- All wrong: 32% conformity
- One ally (correct answer): 5% conformity
Difficulty:
- Easy task: Lower conformity
- Ambiguous task: Higher conformity
