Also crystal healing and conspiracy theories hadn't really been invented yet! Both are offshoots of the 1960s and 1970s counterculture, which was both anti-science and anti-government. Obviously the big exception in conspiracy theories is antisemitic stuff like the protocols of Zion, which had been around for quite a while, but the invention of the national security state in this same period really goosed conspiracy theories, partly because many of them weren't wholly untrue in the era of Cointelpro and the like. It's not paranoia if they really are out to get you.
