What could be a sign of 'confirmation bias' in a group discussion?

Confirmation bias refers to the tendency to favor information that aligns with one's pre-existing beliefs while disregarding evidence that contradicts those beliefs. In the context of a group discussion, a clear sign of confirmation bias is when some opinions are disregarded simply because they conflict with the popular beliefs held by the group. This behavior indicates that the group members are not fully engaging with all perspectives and are dismissing valid points that may challenge their views.

By ignoring dissenting opinions, the group reinforces its existing beliefs rather than evaluating all information critically. This dynamic can stifle discussion and reduce the quality of decision-making, as it limits the exploration of alternative viewpoints and the potential for more robust conclusions.
