Cognitive biases have a big impact on how groups work together. They can really affect how decisions are made and whether everyone agrees. Some common biases in groups include groupthink, confirmation bias, and the bandwagon effect.

Groupthink happens when everyone in a group wants to get along so much that they end up making poor decisions. Members might ignore different opinions and not think critically about other options. This often happens in places where fitting in is seen as more important than being unique, which can limit creativity and even lead to serious mistakes.

Confirmation bias is when people only look for information that supports what they already believe. In a group, this can steer conversations towards only the ideas people already like, leaving out important viewpoints that could help make better decisions. When groups fall into confirmation bias, they just keep following old patterns without checking if they still make sense. This can lead to sticking with wrong or ineffective plans.

The bandwagon effect is when people start doing something just because others are doing it. This bias can pressure group members to go along with popular opinions, even if those ideas aren’t correct or helpful. It can make it hard for people to think for themselves or voice their own opinions.

In short, cognitive biases like groupthink, confirmation bias, and the bandwagon effect greatly influence how groups interact. They can lead to decisions that focus more on getting everyone to agree than on making thoughtful and careful choices.
