How so? Let's take what most would consider a shallow action. Say a high school student start wearing a certain type of shoes because everyone else is wearing that type of shoes. In that example the crowd's motivation for wearing those shoes is to look cool. Wasn't the high school student who wore them because everyone else did also trying to look cool?
Or for a more adult example, take the last election. There were people on my corner holding up Barack Obama signs. Signs, by their nature, are an act of peer pressure (since you can't make a full, reasoned argument on a sign). So the question is this, would those people with the signs be happy if I joined them in holding up a sign but then turned around and voted for McCain? Of course not, because their goal was to get me to adopt their cause not just mindlessly follow them.
