I think you could "generalize" any pyschological problem to that. Every psychological problem, by definition, means thinking things that are harmful. Thinking requires attention, and if you know they are harmful, presumably it is a lack of control that makes you think them.

But I don't think that's a particularly useful generalization in most cases. Unless a person has general problems controlling their attention, then the likely culprit for negative thoughts is not attention control in general, but something related to why those thoughts in particular are prevalent.

In other words, if you eat rocks, the most likely explanation is pica, not gluttony.
