I think sometimes people blur the terms malignant and intense. I interviewed at UCSF a couple weeks ago and loved it. The residents asked us all right off the bat if we had heard any rumors about UCSF so they could address them. Someone said they heard UCSF was "intense" and the residents agreed that you work very hard during certain rotations, esp the medicine months, and night float at the VA. But they were all very happy and enthusiastic about the program, and the faculty I met were very interested in training, and I sensed a lot of camaraderie between the residents and faculty. I did not get the feel that the program was "malignant" in any way. And honestly, if the "worst" thing about a program is that you have to work hard on your medicine months, I can handle an intense 4 months of medicine out of the next 4 years. But everybody's got their own priorities.
I had also heard some stuff about Duke being overly intense, but having interviewed there yesterday, I realized that all of the negative stuff I heard (which wasn't much) was referring to the medicine program, and had nothing to do with the psych program, which I loved. (I don't know how I'm going to come up with my ROL, since I love so many programs already, and I'm only halfway through interviews!)
And I echo what mosche said about Vanderbilt. They've been without a chair for a while, but a strong new chair is starting this Jan. The residents are extremely happy, and the PD is great, so I wouldn't consider it "malignant" in any way either.
Anyway, I haven't heard of any psych programs being truly malignant. When I think of malignant, I think of the kinds of things people are saying in the Duke family med threads. Which doesn't mean I think the Duke FM is malignant - I have no way of knowing, having never met anyone from that program - but nobody is saying those kinds of things about psych programs that I'm aware of.
I think the best prognosticators of malignancy are probably resident happiness and the PD. It's hard to have a malignant program with a good, responsive PD.
