What's the point? Psychiatrists don't like the word "insane": it's too vague. Most mentally ill people seem pretty normal much of the time, and conspiracy theorists are just hung up on conspiraies. You can be perfectly sane in almost every way but still be a kook in one particular irrational way.

Nazis and Mongol hordes weren't "insane" either. Just really dangerous.

Despite what the researchers seem to believe, a conspiracy theory supported by incontrovertible facts (like 9/11 and the Lincoln assassination) is rather different from a conspiracy theory supported by ignorance, illogic, wishful thinking, and the simple conviction that if it weren't true you wouldn't have thought of it. (Take your pick of those....)

And the first kind of conspiracy isn't a "theory." It's a conspiracy.

What's more, the research method, as described above, was incredibly flawed. The "antis" who bother to post to a website in response to a senseless theory are almost certainly more likely to be impatient about the craziness they're reading than the far, far larger group of "antis" who don't care what the "conspiracists" think and are leading real lives instead of posting online like I'm doing now.

Not to mention that for every conspiracy theory there's likely to be an equal an opposite conspiracy theory. The CIA killed Kennedy! No, it was the Mob! No, it was the Military-Industrial Complex! No, it was Castro Cubans! No, it was anti-Castro Cubans! No, it was all of them!

Fact: it was Lee Harvey Oswald, acting alone. Don't believe it? Read the meticulously researched books by Gerald Posner and Vincent Bugliosi and get back to me. You can listen to the CDs if you prefer.
