Frequently in group decision-making situations, people are asked one after the other what decision they have made. This form of sequential decision-making is a popular process in many groups, however, new research has found that there are significant issues with this approach.
Many previous studies have shown that individuals tend to act and make decisions that are biased towards their own ingroup and against outgroup interests. This form of herding behaviour has been shown to exist in boardrooms, judges’ decision making, politics and a range of other situations. In particular, a 2018 study found that the order in which people announce their decision can have a significant impact on inducing conformism with a group decision.
