I start off with this assertion:
Conspiracy theory x is a hoax to derail us from investigating the real truth about the incident y.
You could put in 9/11 truth for x and 9/11 if you like. But I will keep it general. I wouldn’t want to exclude the UFO crowd, the Elvis is alive crowd, or anybody else for that matter. As long as you have a conspiracy theory, I can make it recurs.
Now, let’s call my conspiracy theory CT1. I go on to make claim CT2:
Conspiracy theory CT1 is just a hoax to derail us from investigating the real truth about y.
I continue adding conspiracy theories, CT3, CT4, CT5, and so on, each one claiming that the previous one is just a hoax. I get the generalized form CTn:
Conspiracy theory CT(n-1) is just a hoax to derail us from investigating the real truth about y.
I’ve got a recursive conspiracy theory! Apply it to your favorite conspiracy and you can spend the rest of your life not only questioning the original fact y but yourself as well. There is no exit to the loop, so your children, grand-children, great grand-children, and so on, can continue with this pursuit. See? I’ve given meaning to your life and to the lives of many generations to come.
Oh, and never mind the fact that there is no evidence supporting any one of these theories. This are conspiracy theories, after all. Science is itself just a hoax to prevent us from investigating the real truth. Oops, That last sentence was a hoax. As was the previous one………
