This is the list they compiled, with a little hash if it was in the DSM-V before this study:<p>• Persecutory/paranoid #<p>• Reference #<p>• Family/relatives<p>• Grandiose #<p>• Passivity<p>• Schneiderian<p>• Neighbours/friends/associates<p>• Spied on/watched<p>• Paranormal<p>• Sexual<p>• Poisoning<p>• Religious<p>• Control #<p>• Mindreading<p>• Special powers/skills<p>• Infidelty<p>• Bizarre #<p>• Perception<p>• Thought broadcast #<p>• Somatic #<p>• Police/secret agent/army<p>• Religious leader/God/Prophet/Saint<p>• Thought insertion #<p>• Jealousy #<p>• Guilt/sin<p>• Made affect<p>• Hypochondriacal<p>• Fantastic delusional memories<p>• Thought withdrawal<p>• Erotomanic heterosexual #<p>• Possession<p>• Primary<p>• Catastrophe/world catastrophe<p>• Poverty<p>• Nihilistic/negation<p>• Spy/surveillance<p>• Made impulse<p>The authors’ primary goal appears to not have been to shed light on the diversity of delusional experience, but to indicate some evidence that it is culturally sensitive, so right after this chart, we get into the discussion section and it discusses how in East Asia you can find slightly more delusions of jealousy, in Eastern Europe you can find slightly more delusions of guilt/sin, in their dataset.<p>Reinterpreting it as this press release does, as a survey of the variety of delusional experience, makes for some interesting food for thought, but a lot of the categories identified kind of are just who are you being paranoid about, and what do you think they are doing. So you might have thought that people are afraid of strangers, this data set points to them being more delusional about family members, or thinking strangers are government spies, it's perhaps surprisingly not a stranger as a stranger that is terrifying? (Compare e.g. with the widespread worry among parents that a stranger might abduct their child.)<p>The passivity delusion (“I’m not in control of my body, someone else takes over”) and Schneiderian delusion (which I think is “someone is narrating my life in a Stanley Parable-esque way”?) seem like solid omissions on the DSM-V's part, but after that I feel like I am scrolling down to hypochondriacal and “Fantastic delusional memories” (which is presumably something like “I actually went to Narnia when I was a kid, it's a real place”?) before I see things that genuinely strike me as, I didn't realize some folks have those delusions in their schizophrenia or whatever.
