Herd Behaviour

Herd Behavior is involves people using the actions of others as a guide to sensible behavior, instead of independently seeking out high-quality information about the likely outcomes of these actions.

Here, people not take their independent decision, they see, observe others decisions and driven by those decisions. They are not going to evaluate other’s decision before using it as benchmark, just follow other’s decision blindly.

This kind of mentality originally seen in animals as they follow groups and roaming under the group. Same as humans follow their group and follow decisions of group.


Stock market bubbles, 2008 global crisis, and so on are the examples of herd mentality.
