In this unit, we'll use models to explore how our assumptions about social influence affect the long-run distribution of opinions in a population. The greater the extent to which people are influenced only by those who are similar to themselves, the more distinct communities will form. If we also seek to distance ourselves from those with whom we disagree, the result can be polarization and extremism.
