How Are Truthers Like Rubber Duckies?
A fine article by Michael Shermer.
The belief that a handful of unexplained anomalies can undermine a well-established theory lies at the heart of all conspiratorial thinking (that includes, in addition to Holocaust denial, creationism and crank theories of physics), and is easily refuted by noting that beliefs and theories are not built on single facts alone, but on a convergence of evidence from multiple lines of inquiry. All of the “evidence” for a 9/11 conspiracy falls under the rubric of this fallacy.
Indeed. The Truthers are also like the IRA; they believe that the government has to be right about everything, while they only have to be right once.
