AG,

Yeah, the article is certainly a bit matter-of-fact, owing to the intended audience. It's also true that he lists a lot of possible factors in ET, all of which may or may not apply to a given individual.

Something that strikes me about psychodynamic folks in general is that they really think nothing of discussing sadism, jealousy, murderous rage, manipulation, etc. in their clients, which is shocking at first and yet they do it without the slightest hint of judgment. I was at a meeting of a psychoanalytic group recently and after discussing a case, someone in the audience asked if the client was aware of her rage at her mother. Everyone took it for granted that this client did in fact have rage, based on her childhood, just as they would assume the ground would be wet after a rain. I actually found it oddly refreshing.
