I agree. But emotionally, different articulations of the same thing has different effects. Like if he said for example, some people are genetically predisposed to negative thinking, but with more conscious effort and commitment this can be overcome, is more acceptable, at least for me, than merely saying that our thoughts caused our depression and anxiety, implying that we are responsible of our depression and anxiety in the first place. I don't think people choose to be more negative than normal people. There must be some biological factor. My objection is just about the articulation.
