why is groupthink dangerous 
groupthink may cause people to ignore or reject important information ultimately leading to poor decisions and errors in leadership 3 these errors can sometimes result in disaster or unethical behavior because the key decision makers are unaware of potential risks and contrarian viewpoints have been silenced groupthink is particularly dangerous in political situations where decisions are made through collective deliberation and no single member of the group has enough knowledge to make an informed decision 1 members of the group may feel pressure to conform to the consensus or pressure other members to conform this may result in the false perception that the group is unanimous creating even more pressure for group members to hide their misgivings 3
