psychotic style

I'm guessing, it's supposed to be an innocent observation, like "dresses outside the norm". But yeah, not sure why something like that makes it into a symptom list...

Eh. Some of the social norms are "doesn't scream at people" and "poops in the public toilet, not all over the walls" and sometimes "dresses oddly" is things like "nothing but a bikini in -20F weather" or "instead of pants, wearing a t shirt with the penis hanging out of the neck hole" but yes many of them are bullshit. For instance I hate it when psychiatrists mark the mannerisms of a man from the lgbt "Queen" subculture as manically elevated or one time I had a patient piling shitty toilet paper next to the toilet who was just used to having a trashcan there in his home country. So if you're good at what you do you're always learning and growing and paying attention to context and thinking critically. Unfortunately the world we live in is full of many incompetent people in many areas and often the best we can do is work around them. If you think you can do better I invite you to come try. That's what I did, and sometimes I do actually do better, and it is pretty fulfilling when you succeed at it. Other times you're just getting screamed at for looking like a demon today, but it's ok because if you offer some Lorna doones to get the haldol to go down you'll be an Angel again in a few hours.

House would not make a point like that unless there was some diagnostic significance.

House would do something like notice from the weird colour schemes on their clothing how their colour perception is affected which is an indication towards a rare disease or something.

This doctor is just prejudiced.
