The thing that makes conspiracy theories difficult to extract as
well, is there governments, corporations, ANY public relations
department _does lie_ sometimes.
The father of modern Public Relations, Edward Bernays back in
the 1920s encouraged a shift away from using the word Propaganda
to disassociate the USA from Germany and instead use "Public
Relations Department".
Propaganda wasn't a bad word originally but it turned into one.
So, they have a point. That's what makes it tough - they do have
a point.
Plus, we love puzzles. Very smart people often get involved in
conspiracy theories. I've known more than a few Mensa+ level
people who get wrapped up in them. [see Chomsky for modern
example. Smart dude but sometimes... ]
It makes logical perfect sense when put together just the right
way.
But... there's missing variables. There's ALWAYS missing
variables that are outside of the Universe of their theories.
Since they're inadmissible as evidence to their theory, they
can't be used to refute it.
