Groupthink is a type of thought within a deeply cohesive group where members try to minimize conflict and reach consensus without critically analyzing ideas. An example is an Air Force team that developed a new mail system process taking 19 days instead of the previous 8 day process, even though members knew it was worse, due to not wanting to question team solidarity. Another example is an executive who questioned a company's strategy of free storage but was dismissed by younger executives, and the company later went bankrupt. A third example is an entrepreneur who tried to change a company's model but was dismissed by the CEO, and the company later lost money. Factors contributing to groupthink include size and cohesiveness of groups, limiting discussion to few alternatives
