Group Thinking makes me think about Bystander Effect;a social psycholigical phenomenon that refers to cases where individuals do not offer any means of help in an emergency situation to the victim when other people are present (wikipedia, 2012).
This is due to some sore of justificstion of individual in the situation under social influence. People witnessing emergency situation and hesitate to offer help because they observe that there are other people who also bystanders that do not take any action.
It is very easy to be swayed by majority's idea when you are uncertain about something and especially very hard to think critically for yourself when a team or a group of people had established that majority's idea is right and make a gesture that anyone else should not have any other ideas that go against it.
However, in team decision making, another big obstacle is to get everyone heard and to get every idea a chance to be considered. Our minds tend to be closed for something new or something else that doesn't go along with what we believe.
And democracy in team's decision making can hinder bias towards siding with majority, thus, voting for decision is not always a good solution to make robust decision. Anchoring decision making tools in the process will help identify factors relevant to decision and generate solid information to minimise bias in judgement.
How many times this group thinking goes unnoticed in an organisation..???
