Halo Effect

Halo Effect

http://jamesthornton.com/theory/theory?theory_id=24
The extension of an overall impression of a person (or one particular outstanding trait) to influence the total judgment of that person. The effect is to evaluate an individual high on many traits because of a belief that the individual is high on one trait. Similar to this is the 'devil effect', whereby a person evaluates another as low on many traits because of a belief that the individual is low on one trait which is assumed to be critical.
