Answer:
Groupthink is the most dangerous type of social activity when trying to solve a problem. Group norms are the guidelines which we follow in order to be part of an in group or primary group. It is because we follow these guidelines or rules that we are affiliated with this certain group. For example, a "prep" will wear certain clothes in order to be identified as "preppy," thus, making the individul feel accepted by others, within the same in group. However, as a result because one will conform ones idea's and beliefs or in the example apperance, one is also more likely to loose all individuality and creativity. Thus, when an issue is studied via groupthink we are less likely to study other alternative solutions to the problem.
