I keep looking for a term I knew -- it's somewhere in the [[Agora]].
In its place, I currently have [[mind hazard]] by association with [[bio hazard]].
@agora I meant https://www.lesswrong.com/tag/information-hazards ~ [[info hazard]]
@agora [[Nick Bostrom]] shows up as I expected; he was the other Agora entry point that I thought could lead me back to the term in common usage.
