Halo effect
The halo effect (sometimes called the halo error), a term coined by Edward Thorndike, is the tendency for positive impressions of a person, company, country, brand, or product in one area to positively influence one's opinion or feelings of a person, company, country, brand, or product in another area. It is "the name given to the phenomenon whereby evaluators tend to be influenced by their previous judgments of performance or personality;" in other words, it is a cognitive bias that can prevent people from forming an image based on the sum of all circumstances at hand.
