Groupthink- the tendency of group members to conform, resulting in a narrow view of some issue.

Out-group- a social group toward which a person feels a sense of competition or opposition.

Rationality- a way of thinking that emphasizes deliberate, matter-of-fact calculation of the most efficient way to accomplish a particular task.
a. Stewie possesses much rationality in his thinking. Throughout the show he is trying to kill Lois because he is an evil, genius baby.

Dyad- a social group with two members.
a. Throughout many episodes in the show, Stewie interacts with his teddy bear named Rupert.

Triad- a social group with three members.

In-group- a social group toward which a member feels respect and loyalty.
a. Many episodes show a group of friends together (usually at the Drunken Clam) that includes Peter. His main friends in this in-group would be Cleveland, Quagmire, Peter, and Joe. They are best friends and spend countless hours together talking about random things or doing random activities.

Network- a web of weak social ties.
