Explanation:
Herd instinct is a mentality that is distinguished by a lack of individual decision-making or introspection, causing people to think and behave in similar fashion to those around them. The fear of missing out on a profitable investment idea is often the driving force behind herd instinct. Human herd behavior can be observed at large-scale demonstrations, riots, strikes, religious gatherings, sports events, and outbreaks of mob violence. When herd behavior sets in, an individual person's judgment and opinion- forming process shut down as he or she automatically follows the group's movement and behavior. Herd behavior in humans is frequently observed at times of danger and panic; for example, a fire in a building often causes herd behavior, with people often suspending their individual reasoning and fleeing together in a pack.
