Why is conformity bias a problem?

Conformity bias is a problem because it can cause us to stop thinking for ourselves. This means that we no longer exercise our own judgment or rely on our own values to decide how to act. Taken to its extreme, conformity bias can lead to a “herd mentality,” or the tendency to follow the direction of a group without question. This can cause us to suppress our true opinions, espouse dangerous beliefs, or engage in illegal acts.
