Answer: Assembling perspective
Explanation:This is a theory that focuses on collective behavior and collective action according to this perspective people feel as if they are acting rationally if they are acting in numbers. For example flash mobs, which occurs when people get involved in an non institutionalised activity because they feel pumped up by the mass of the crowd. Some people collectively adopt the same hairstyles especially teenagers and they will feel that is rational when they are all doing it.
