Explanation:

Groupthink occurs when all members of a group think the same, or reach the same conclusion. This can be positive when group members reach a consensus in an informed, and conscious way, but groupthink can also be negative, or even dangerous, when people choose to go with the group even if the group consensus is against their own ideas, values, or morals.
