The belief or attitude that one is superior to others and considers themselves better than everyone else is called "arrogance" or "egotism." Arrogant individuals often have an exaggerated sense of their own importance, talents, or achievements and may look down upon or belittle others they perceive as inferior. This behavior can lead to a lack of empathy, a dismissive attitude towards others' opinions and feelings, and an overall negative impact on relationships and social interactions. Arrogance is generally seen as a negative trait and is not well-regarded in most cultures and societies.
