Evaluate the extent to which peer pressure can impact negatively on intrapersonal conflict

Peer pressure is a form of bullying. It can negatively affect someones behavior or mod in their perspective.

So peer pressure can negatively affect a person in one big way - kind of like the bandwagon argument method ("if you don't do it, you'll be left out!"). This person can be affected by the threat of "not being cool" or "not being a true friend."
