Final answer:
The statement is true; trying to fit in with a group due to the desire for friendship exemplifies external pressure and is part of normative social influence.
Step-by-step explanation:
The statement that trying to fit in with a group of people because you want to be friends with them is an external pressure is true. This reflects the concept of normative social influence, where individuals conform to a group norm to fit in, feel good, and be accepted by the group. This is a natural sociological behavior observed among youth and college students, as they navigate the complex social environment and try to find their place within various in-groups and out-groups. The extent to which an individual conforms to these group norms or expectations can vary, and it is influenced by the desire to be liked as well as the desire for accurate information from the group.
