Maxwell Maltz, the creator of the program and methodology Psycho Cybernetics, was a plastic surgeon. Plastic surgery, as a rule, is to make someone more beautiful.
Many of his patients, though, didn’t get what they hoped for. Everyone said that they were beautiful, but they could not see their new you, only the ugly that they wanted to get rid of.
We could say that they had a filter that allowed only the imperfections through. I think that this “theory” is more accurate than Maxwell Maltz’s theory of self-image.
