In-class notes about Hogg (meta-contrast, prototypes)

Meta-contrast is the ratio of between group differences and within group differences.

Prototype of a social category is determined with this ratio, and helps explain why the average of the group beliefs is not the prototype.

Some implications of meta-contrast in group identity formation:
- Groups pick a prototype that maximizes this ratio; polarization happens b/c people move towards the prototype
- Decisions about who is in and who is out are based on this prototype
- Leader of group tends to be close to this prototype
