Definition:

The Bandwagon Effect is a psychological phenomenon in which people do something primarily because other people are doing it, regardless of their own beliefs, which they may ignore or override. In a meeting when someone disagrees to an idea initially but decides to get along with the group is an good example of “bandwagon effect”. People assume that if everyone else is going along with something, their own reservation is silly or miss-informed, and they don’t want to look stupid in front of the group. This group thinking isn’t a individual failure but an human failure.

The bandwagon effect has wide implications, but is commonly seen in meetings, group discussion as an  employee’s behaviour.
