Taking one characteristic of a person and applying it to the whole person. Attributing a person’s behaviors to their character or personality rather than thinking it’s
temporary or just for one event.

A person who labels takes all-or-nothing thinking to an extreme level, where in addition to blaming oneself or others, they will also attach a negative label to said person.

Examples: This is who she is all the time, I don’t think this is just a one-time mistake. That driver honked at me at the intersection so he must be an angry person in general.

Tip: Try asking yourself questions and see if what you think is really true.
