People who are intelligent but don't act like they're better than everyone else are often referred to as "humble" or "down-to-earth." These individuals possess the ability to acknowledge their intelligence and expertise without displaying arrogance or a sense of superiority over others. They may also demonstrate traits such as modesty, open-mindedness, and a willingness to learn from others, regardless of their own intelligence level. Being humble is generally seen as a positive trait, as it fosters better communication, understanding, and collaboration with others.
