Whilst that might true as per your observations, I've also seen people do zero research, take a substance in the wrong place/frame of mind, and subsequently had a more turbulent experience than they were expecting
We often attract certain types of people, and have a wealth of experience with that type.
We probably all take this as obvious knowledge. But only when I uncomfortably enter a group of people unlike me -- and feel totally alienated not just by their norms and assumptions, but their misunderstandings of my own -- only then do I truly confront the implications in a visceral, non-academic sense :)
