Hi, I’m one of those people. None of the stuff I’ve read and precious few techniques have helped. It’s kind of the hallmark of these cognitive distortions that they’re irrational and we know they’re irrational and yet they persist.

There is a book, but you don't need to read much past the first few chapters, named "Feeling Good", by Dr. David Burns. He and another (I don't remember the other doctor's name) developed the Cognitive Behavioral Therapy school of psychology.

The gist is there is a simple list of questions one can ask themselves that expose self deception in one's self conversation. Once the deceptive self conversation is identified, the deception naturally becomes nullified. These deceptions are things one tells themselves that are not known, not true, but the self accepts the statements and internalized them - causing imposter syndrome and a huge number of related negative emotional cycles. The simple act of identifying these deceptions causes one's own mind to re-evaluate, and if the new evaluation contains more deceptions that same Cognitive Distortion checklist can be reviewed and used to discard these new comforting lies or negative projections.

Note that this is not a casual pursuit. This a a "debugging and reprogramming your core beliefs". In cases where one has never performed such a self audit, I suggest doing so with the support of a licensed therapist; it is not a casual event, to reevaluate one's entire world view in light of realizing one's level of self deception.

I have seen amazing results, and experienced them myself.

Thanks for making a specific recommendation and going into what makes it work. I also appreciate the note of caution; people seldom talk about the negative affects of self inquiry.

Until you wise up, and you start using your own behavioral analysis as the avoidance mechanism.
