Black-and-white thinking, also known as "all-or-nothing" or "dichotomous" thinking, is a type of cognitive distortion where a person views situations, people, or events as either completely good or completely bad, with no room for shades of grey or complexity.
CBT therapy is a highly effective type of therapy to help shift this type of unhelpful thinking. CBT is an effective therapeutic approach that can help people change their extreme and black-and-white thinking patterns by challenging and replacing their negative or distorted thoughts with more realistic and flexible ones.
