> I have been thinking a lot about a notion of self-paradoxical knowledge, meaning knowledge that actively makes your reasoning worse.

There could be a hypothetical class of ideas that just knowing about them is actively harmful. For a fictional example, imagine learning how to detect a hostile alien race that has been living with us on earth all this time. Or if one day we invent a thought experiment that induces psychosis to anyone that tries to unravel it.

I think the keyword for these type of ideas is infohazard: https://en.wikipedia.org/wiki/Information_hazard - the See Also section has a few interesting examples.

I had seen this, but all the examples correspond to having an actual, external threat as a result of this knowledge. I thought more about the buddhist parable that men don't know when they'll die, because only buddhas are able to live with this information. I guess it's very close to 'malinformation', but this is still related to an external actor manipulating what you know with an external goal, rather than intrinsic to the information.
