When narcissists encounter criticism, they often react with a range of intense emotions. Anger and defensiveness are common initial responses, as narcissists perceive criticism as a personal attack on their character or abilities. They may lash out at the person providing the feedback, attempting to discredit or intimidate them to maintain their superior self-image. Additionally, narcissists may experience profound feelings of hurt and wounded pride, as their high sensitivity to criticism leaves them feeling exposed and vulnerable.
