The view of the group matters.
See, if you identify as part of group X, the more likely you will be to align yourself with the characteristics and ideas of group X.
Does that make sense?
For example, I am not from West Texas but I graduated from Texas Tech and I live here now.
I have no real reason to despise Texas A&M, but I have grown to do so.
Red Raiders dislike Aggies and – well – I’m a Red Raider.
This seems silly, but it has larger implications.
For if you can get a group as a whole to lean a slightly certain way, aren’t you simultaneously persuading the individuals too?
PERSUASION TIP 1: When you identify as part of a group, your opinions tend to be biased toward the group consensus.
