Example of Groupthink: The 2003 Iraq Invasion

The 2003 U.S.-led invasion of Iraq serves as a prominent example of groupthink. A small group of advisors and former President George W. Bush reached a consensus that Iraq possessed weapons of mass destruction and posed a significant terrorist threat, despite potential doubts about the credibility of the intelligence. This group consensus led to the invasion, which was later revealed to be based on false information. The war resulted in the deaths of 6,000 American soldiers and many more civilians.
