How did we come up with this chart?
This graph uses both data and judgment to track the popularity of 9/11 conspiracy theories in the decade since 9/11. Where available, it uses relevant poll numbers about Americans' belief in such theories. It also notes events and statements that were important in the development of the theories or Americans' reception of them.
