I can understand that the term "dumb narcissist" is used colloquially to describe someone who exhibits narcissistic traits but lacks intelligence or wisdom.
Narcissism is a personality trait characterized by an excessive preoccupation with oneself, a sense of entitlement, a need for admiration, and a lack of empathy for others. It is essential to remember that intelligence and narcissism are separate traits, and one can find individuals who display narcissistic behavior across a wide range of intelligence levels.
People with narcissistic traits may exhibit behaviors that can be harmful to themselves and others. However, it's important to be cautious about labeling someone as "dumb" or making sweeping judgments based on a single aspect of their personality. Every individual is complex and multifaceted, and it's essential to approach others with empathy and understanding while also setting healthy boundaries when dealing with challenging personalities.
