Cognitive Distortions are at the core of what many cognitive-behavioral and other kinds of therapists try and help a person learn to change in psychotherapy. By learning to correctly identify this kind of “stinkin’ thinkin’,” a person can then answer the negative thinking back, and refute it. By refuting the negative thinking over and over again, it will slowly diminish overtime and be automatically replaced by more rational, balanced thinking.
