Dealing With Delusions

If you’re prone to forming delusions, but you’re good at checking your beliefs against reality, you might manage to avoid going off the deep end, but that doesn’t mean escape unscathed.

Amphetamine use can make you imagine the people in your life are plotting against you. A good rationalist will notice they lack evidence and that the prior should be pretty low, but they’ll still be left with whatever cognitive patterns threatened to generate that delusion.

Psychedelic use can make you believe stuff in the “all is connected” space. A good rationalist isn’t going to start believing parapsychological phenomena are real because of something they experienced on an LSD trip, but they’ll still be subject to the cognitive patterns that tend to make some others believe such things.

Schizophrenia can make you see corruption all around you or imagine your own persecution. On the margin, practice in rationality might be a bulwark against schizophrenic delusions (these statements have not been evaluated by the Food and Drug Administration; LessWrong is not intended to diagnose, treat, cure or prevent any disease). But while you might save yourself from believing the CIA is after you, you wont save yourself from the cognitive patterns that tend to give rise to such delusions.

When you become subject to a new bias, as long as it doesn’t obviously put you out of touch with reality, it can be tempting to image that what’s really happening is you’re getting smarter. Now it’s just the way you think, and these biases can be self-reinforcing.

Look, I know my co-workers hate me, I’ve seen what they say when they think I’m not looking. If my increased Adderall dose has anything to do with it, I should be happy it slapped my out of my naivete. You just want me to stop taking it because you’re jealous.

A lot of the times we acquire a new cognitive pattern, it is because we’re getting smarter — that’s a big part of growing up, and we grow up at a formative time in our lives. How do we know which new cognitive patterns to be suspicious of? My recommendation: take the outside view.

Try to figure out where a new cognitive pattern might have come from and look at how similar patterns with similar causes have played out in other people. Amphetamine paranoia, for instance, has few accomplishments to its name, and many people under its influence arrive at beliefs that don’t match reality. If the pattern arose around the time you increased your amphetamine dose, it’s probably not making you smarter, and you should be suspicious of any new paranoia-adjacent beliefs.
