social psychology
You assume a person's appearance reveals their inner character.
A single positive trait leads people to assume other unrelated positive qualities exist.
First identified in 1920, the halo effect shows that once you perceive one attractive feature—such as physical beauty or a warm voice—you automatically attribute social competence, intelligence, and kindness to that person. Your mind is prone to building a coherent narrative about someone based on a minimal set of surface-level data. You rarely see a person as a collection of independent traits.
Your initial impression acts as a lens that distorts all subsequent information.
