In the book Blueprint, Nicholas Christakis identified a ‘social suite’ — a range of eight traits that are common among all human societies, though not always manifested in the same way — based on broad historical and anthropological research.
- Individual identity
- Family love
- In-group bias
- Friendship
- Cooperation
- Egalitarianism
- Social networks
- Social learning
A similar ethnographic study which examined ethics from 60 societies, across over 600 sources found seven universal rules of morality.
