<h3>What is groupthink?</h3>
Groupthink is a phenomenon that happens when people's rational desires to offer alternatives, challenge a viewpoint, or voice an unpopular opinion are suppressed in favour of group consensus. Here, the need for group cohesiveness effectively stifles wise judgement and creative problem-solving.
Characteristics of Groupthink Behavior are-
- Direct pressure: The in-group and the out-group are the two camps that groupthink separates into. A decision is accepted by the in-group, while the out-group challenges it or objects.
- The appearance of invulnerability: When there is no room for discussion or opposing viewpoints, in-group team members feel overconfident and take more risks when making judgments.
- Direct pressure: Groupthink breaks into two camps: the in-group and the out-group. The in-group agrees to a choice, whereas the out-group questions it or objects.
- Self-censorship: Groupthink victims will suppress any ideas or viewpoints that differ from the group's. They might even start to question their ideas and convictions.
- Reasoning: Groupthink promotes participants to discount any outside information, particularly cautionary or critical messages. If they pay attention to this information, they might reflect more deeply or change their minds.
