Herd behavior is a concept used to describe the collective behavior of a group of individuals who act in the same way. The term can be interchangeable with words such as groupthink, mob psychology, and conformity. Groupthink describes a situation where individuals in a group prioritize consensus over critical thinking, leading to a lack of diversity in opinions. Mob psychology refers to the tendency of individuals to follow the actions and emotions of a crowd, often leading to irrational behavior. Conformity is the act of changing one's behavior to align with the norms of a group. These synonyms all illustrate the dangers of blindly following the actions of others without thinking critically.
