- •
A DeGroot-like opinion dynamics model with in- and out-group structure is proposed.
- •
Agents want to coordinate with their in-group & anti-coordinate with their out-group.

Model predictions include persistent disagreement in connected societies.

Necessary and sufficient conditions for bi-polarization are determined.
- •
We also determine opinion leadership and discuss (crowd) wisdom.
