In CBT they tell you to challenge automatic thoughts. So say someone doesn't say hello to you, then you think he doesn't like me. CBT says to challenge this and maybe you realize that he didn't see you actually.
I have a more philosophical question in such sense. CBT assumes that at some point we are generating wrong ideas (automatic thoughts) and later we are able to correct them ourselves. My question is, if we are able to correct them, why are we generating the wrong ideas in the first place? What is the mechanism that allows this to happen? Which mind processes are in play here? Concious/unconcious?
