A person who only likes others based on their appearance, and doesn't consider other aspects of their personality or character, is often referred to as "superficial" or "shallow." Such individuals prioritize external attractiveness over other qualities like intelligence, personality, values, or compatibility.
It's essential to recognize that superficial judgments can be harmful and limiting, as they overlook the true essence of a person and can lead to missed opportunities for meaningful connections and relationships. People are multi-dimensional, and focusing solely on appearance can prevent one from appreciating the depth and uniqueness of individuals. Building relationships based on shared values, interests, and emotional connection tends to lead to more fulfilling and enduring bonds.
