Explaining the process of change
Hearing something u agree with doesn't make u stop and think but if its something new then u might think more deeply about it especially if the source of this other view is consistent committed and flexible
This deeper processing is important in the process of conversion to a different minority viewpoint
Over time increasing numbers of people switch from the majority position to the minority position - conversion
The more this happens the faster the rate of conversion called the snowball effect
Gradually the minority view has become the majority view
