You’re in a meeting and someone says something wrong, but you say nothing because everyone else stayed silent. This is a clear example that many people can relate to, where we are ‘forced’ to conform, by our brains.
Conformity is adjusting your behaviour, beliefs or opinions to match a group, and it happens more often than you think.
There are three main reasons behind it:
- Normative social influence (the need to be liked):
We have a fear of rejection and worry that standing out or breaking unwritten rules will lead to social punishment or isolation
We also have a desire for approval, and conforming helps us gain acceptance and feel like we belong to a community
Many people change their outward behaviour to match the crowd even though they inwardly disagree
- Informational social influence (the need to be right):
When we face confusing or new situations and lack knowledge, we assume that others know more than we do.
We often copy the actions of the group to make fast, effective decisions and avoid making mistakes.
- Evolutionary roots
Early humans depended on tribes for foods, protection and raising offspring. Being cast out of a group meant nearly certain death, so we adapted to give ourselves a survival advantage.
And lastly, brain rewards. Brain imaging studies show that when we agree with group norms, our neural reward pathways activate, making conformity feel good physically and emotionally.
The neuroscience behind it:
Going against the group activates the brain’s error detection system (the anterior cingulate cortex). It’s the same region that activates when you feel physical pain. Fitting in is literally a relief.
The Klucharev study found that when participants’ opinions differed from the group, their brains immediately showed error signals – and they changed their ratings to match. They didn’t just say they agreed, they actually changed their perception
The dark side:
The problem is a brain that rewards conformity doesn’t ask whether the group is right.
This is how groupthink happens – a team, a community, a country all converging on a decision nobody individually believes in, because the social cost of dissenting is too high. Unfortunately, especially nowadays we see a lot of views spreading rapidly across social media, and our brains are programmed to follow the crowd and agree with the views of the majority, however this is taking away from our ability to judge for ourselves.
It’s also how ordinary people participate in atrocities. Not because they’re evil, but because the group has normalised something gradually and at each step the cost of conforming was lower than the cost of standing apart.
