Identify your in-groups and your out-groups. how have your in-groups influenced the way you see the world? and what influence have your out-group had on you?
This is a sophisticated question, because it realizes that all people are shaped by others or we can say society. The in-group will, of course, have the greater influence, but the out-group may have a role as well. The person who has done some great work on this topic is the sociologist Peter Berger. His basic thoughts are outlined in the link below. The basic point is that a person's in-group will shape a person's plausibility structure. To put it in other words, what a person deems plausible is large a matter of society.
Since this question is directed to an editor, I would say that my in-group is my family. My family has influenced me in my opinions and how I view the world. As for out-group (probably pop-culture), I would say that it has influenced me in subtle ways through media.
