Groupthink can have a strong hold on political decisions and military operations , which may result in enormous wastage of human and material resources . Highly qualified and experienced politicians and military commanders sometimes make very poor decisions when in a suboptimal group setting . Scholars such as Janis and Raven attribute political and military fiascoes , such as the Bay of Pigs Invasion , the Vietnam War , and the Watergate scandal , to the effect of groupthink . More recently , Dina Badie argued that groupthink was largely responsible for the shift in the U.S. administration 's view on Saddam Hussein that eventually led to the 2003 invasion of Iraq by the United States . After the September 11 attacks , " stress , promotional leadership , and intergroup conflict " were all factors that gave rise to the occurrence of groupthink . Political case studies of groupthink serve to illustrate the impact that the occurrence of groupthink can have in today 's political scene
