Authority bias is a cognitive bias in which individuals are more likely to follow the advice or direction of an authority figure, even if that advice or direction is not in their best interest. This bias is particularly relevant in group decision making, as it can lead to the suppression of dissenting opinions and the acceptance of flawed ideas.

One of the key drivers of authority bias is the belief that authority figures are more knowledgeable or experienced than others in the group. This belief can be reinforced by factors such as formal titles, uniforms, or other symbols of authority. However, it is important to note that authority bias can also be triggered by informal sources of authority, such as charismatic individuals or those who have achieved a high level of success in their field.

In group decision making, authority bias can have a number of negative effects. For one, it can lead to groupthink, where dissenting opinions are suppressed and the group becomes overly confident in their decision. Additionally, it can lead to the acceptance of flawed ideas or poor decisions, as the authority figure's opinion is given more weight than it may deserve.

To mitigate the effects of authority bias in group decision making, it is important to actively encourage dissenting opinions and to create a culture where all members of the group feel comfortable sharing their thoughts and ideas. Additionally, it can be helpful to establish clear criteria for decision making and to evaluate the authority figure's ideas and suggestions using those criteria.
