There were books in the 1970s debunking the Bermuda Triangle, von Daniken, etc, but I didn't want to read them. Instead, as I read more of the woowoo, I started noticing contradictions and other silliness and started thinking, hey, wait a minute. As I recall, von Daniken's fourth (?) book seemed to almost completely contradict his earlier books, going from aliens did it to God did it. A book on the Bermuda Triangle -- which was supposed to be a strange and unique regional phenomenon -- claimed that actually there were a lot of places where ships and planes disappeared. I assume the author was going for an "oh wow it's bigger than I thought" reaction but I had an "oh stuff happens everywhere, so there's nothing special about this area after all" reaction. The same author, running out of material, also added chapters about ghost stories in the region as more proof of the weirdness of the Bermuda Triangle, and I did not believe in ghosts at all, so that didn't help my willing suspension of disbelief. Then there was the time I bought a UFO magazine. The cover story was a typical "I was taken aboard their ship" story. To prove how strange and alien it was, the author mentioned that the alien controls were labelled in what was clearly an alien language, with words like NXPTQ and FLRGN. It didn't occur to him that an alien language wouldn't use an alphabet from Earth. And then there was the whole pyramid power thing that was just too damn stupid for words (if you keep your razor blade in a pyramid-shaped box, the blade will stay sharp forever!). The Alan Parsons Project even made a concept album about pyramid power.
Between all these things, my suspension of disbelief started fading pretty rapidly. At least science fiction writers tried to make their stories logically consistent.
