Positive vs negative stereotypes

Examples of this include “I’m a lover not a fighter”; “If you think I am scary you should see my owner”; or “look at my vicious dog” (attached to an image of a dog doing nothing vicious whatsoever).
But in terms of psychology, messages that attempt to negate a stereotype (“I am not bad!”) might actually be making things worse by planting or reinforcing the negative message. It might be more effective to affirm a positive message (“I am good!”).
Counter-stereotype: an idea or object that goes against a standardized mental picture that is held in common by members of a group and that represents an oversimplified opinion, prejudiced attitude, or uncritical judgment.
