halo effect




  The halo effect is a cognitive bias of perception of one trait is influenced by the perception of another trait. An example, a good looking person is thought of as more smart.



  A Solomon Asch study suggests attractiveness is a central state, we presume all other traits of an attractive person are just as attractive and sought after.



  The halo effect explains Harold Kelley's implicit personality theory. The initial traits recognized in people are ingrained, influential and impressive. Attractive people held in regard to have a more desirable personality and appear more skilful than someone of average appearance.



  In brand marketing, the halo effect is when perceived positive features extend to a broader brand.

  For example, iPod had positive effects on perceptions of Apple's other projects. In the automobile industry, halo vehicles include the Dodge Viper, Ford GT and Acura NSX.



  Social psychologist Richard Nisbett said even if we were told our judgments have been affected by the halo effect, we may not be aware when under its influence, we might never have known when we've had it so good.
