1. Defensive psychology: Faced with negation, individuals may feel their self-worth is threatened, so they adopt suppression as a defense mechanism to protect their self-esteem and position, and avoid further feelings of frustration.
2. Competitive mindset: In certain situations, negation may be seen as a challenge or competitive signal. Suppressing deniers may be to maintain one's advantageous position in a certain field or relationship, demonstrate one's authority and unquestionable stance.
3. Emotional response: Sometimes, suppressing a negative person stems from strong emotional reactions such as anger, dissatisfaction, or disappointment. These emotions may prompt individuals to engage in aggressive behavior to express dissatisfaction or attempt to change the other person's perspective, even if it is not always effective or appropriate to do so.
