Halo effect

Tendency for positive impressions to contaminate other evaluations

The halo effect is the proclivity for positive impressions of a person, company, country, brand, or product in one area to positively influence one's opinion or feelings. The halo effect is "the name given to the phenomenon whereby evaluators tend to be influenced by their previous judgments of performance or personality." The halo effect is a cognitive bias which can prevent someone from forming an image of a person, a product or a brand based on the sum of all objective circumstances at hand.
