Even the exact phrase "conspiracy theory" predates the CIA by at least 40 years. So it seems the poster's theory about the origin of the conspiracy theory is, reflectively, a conspiracy theory itself. Given that the CIA is so often the subject of such conspiracy theories, I suspect irony might have been employed.

Now I can't tell if the commenter legitimately thinks that no scientific mind would dismiss conspiracy theories or if they're making fun of people who want scientists to entertain conspiracy theories.
