What keeps believers in conspiracy theories going despite the mountains of evidence against them? The Discovery website has a great little article on this very subject that I recommend reading. Follow-the-money quote:
In the case of the TWA Flight 800, we can easily follow the money back to Kristina Borjesson, the writer and director of an upcoming documentary film on the incident. Borjesson’s publicity team has done their job drumming up a “controversy” and rehashing long-discredited conspiracy theories to promote her upcoming film.
Follow the money indeed.
