“Anything that thinks logically can be fooled by something else that thinks at least as logically as it does.”
― Douglas Adams,
With the release of most of the documents regarding the JFK assassination we see an example of one of the main issues regarding conspiracy theories: no matter how much proof someone is shown, it only makes them cling to their belief more and more.
Just look at the all the conspiracies surrounding the moon landing. Regardless of the proof, even if someone were flown to the moon chances are that would only reinforce their belief in the conspiracy.
Of course it doesn’t help that there are plenty of people who are more than willing to prey on people like this and make life that much more unpleasant for the rest of us.
