Answer:
It is also called Bandwagon effect
Step-by-step explanation:
Humans have a biological drive to belong. We seek out social contact, not only because of the life functions it can fulfil, but also because it is inherently rewarding. These neurobiological mechanisms — built around opiate and oxytocin release in the brain — feel great, and make us want to socialise more. This process probably developed to foster social bonding for survival advantage — if our ancestors could bond and co-operate, they were more likely to stay alive.
These principles apply with one-to-one or small group contact, but they also occur at the larger scale: the crowd. Something occurs in crowds that does not happen when we are alone, or even in groups of just a few people. Observers have long recognised that there is something special about the crowd — they just couldn’t agree on what it was.
For much of the past 150 years, our views of crowds were polarised into two camps: crowds were either a terrible thing, or a wonderful thing.
