Episode notes
Groups Are A Powerful Dichotomy
- Groups can be the pinnacle of human accomplishment while also driving extreme conformity and tribalism.
- Colin Fisher frames groups as a dichotomy that can either unleash creativity or suppress individuality.
Prioritize Diversity And Keep Groups Small
- Compose groups with diverse knowledge, skills, and perspectives to create synergy.
- Avoid making groups too large because big groups reduce the chance everyone's perspective is heard.
Ideal Group Size Is Surprisingly Narrow
- Research finds ideal group performance typically occurs between three and seven members.
- People feel groups are the right size around four to five members, a useful practical anchor.
