Oh the Irony..

A person's social identity and groups is amazing sometimes. I have watched people change from one social to group to the complete opposite in short matter of time. One girl went from being the popular sporty girl to environmentally sound and went on a mission to Africa to help children. It was a great change for her but, it is amazing how one person can change so quick just based on the people around them. It is also known that people are more likely to favor other people from their "group".  Or how silly people can act in groups....

It seems groups can have a positive or negative effect on society and the people in them. The social power a group can hold over the people in it is amazing. From peers trying to make you drink or smoke when you don't want to (negative):

Or friends motivating each other to work out(positive):

In a way I would almost consider spouses reference groups also because it has been shown that each spouse will pick up the others habits as time goes on from being around them so much. You tend to eat what the other person likes and also do what they want. I can say for myself I don't eat as healthy as I used to when I was single. But, don't get me wrong that is a sacrifice I am more than willing to make. Attached below is a link that is a little dry but, I think it contains a lot of helpful information: Social Power
