“…As a cognitive bias, the halo effect occurs when people rate a person's performance, personality traits, or specific behaviors based on their overall or previous good impressions or judgments about the person.

Overgeneralization is another type of cognitive bias that may occur when a person generalizes feelings and thoughts about a person or groups, issues, or situations, based on a single example or one set of positive or negative experiences.…”
