On LW it's my default to treat the people I'm speaking with as if they wouldn't be ignorant.

Which is nicely respectful but I feel like my knowledge is being overestimated on LW. I get the impression that I am supposed to know already that neuro-linguistic programming, for example, doesn't work. It's hard to keep up with the latest results in every field. NLP for staters was taught me 7 years ago during a postgraduate course involving software consulting techniques. So I was surprised when I was told not only it is bunk but apparently everybody save me already knows it is bunk.
