Here I mean "serious" in the external-observer sense -- to denote people whom others consider serious = worthy of attention and time. I do NOT mean "serious" in the internal perception sense (as in e.g. "I'm not joking, I'm serious").

Fine, but please help me figure out where the goalposts are. Are the two girls in the videos I linked worthy of attention and time (at the beginning of the video, before they were scientifically tested)? In your opinion, do they have adequate knowledge of human physiology? If not, how do you know it?
What is something you used to believe, preferably something concrete with direct or implied predictions, that you now know was dead wrong. Was your belief rational given what you knew and could know back then, or was it irrational, and why?
Edit: I feel like some of these are getting a bit glib and political. Please try to explain what false assumptions or biases were underlying your beliefs - be introspective - this is LW after all.
