  • What do you think?

  • Would this man make a good doctor?

  • What about him?

  • Would you trust him with your surgery?

  • Most people would probably want to get treated by one, rather than the other.

  • And most people are likely to be wrong about that.

  • When you look at the sun, you sometimes see it clearly.

  • But sometimes you'll see it shining way bigger than its actual shape.

  • That circle of light that makes it look bigger is called a halo.

  • The halo effect also happens when a person, product, or company shines like the sun.

  • Then we don't see them clearly and associate all sorts of unrelated qualities to them.

  • The halo effect was first identified in 1907 by the American psychologist Frederick Wells

  • and was then studied by the psychologist Edward Thorndike, who asked flight commanders to

  • evaluate their officers in various distinct aspects such as physical appearance, intelligence,

  • and leadership.

  • Examining the results, Thorndike found that the officers that got high scores for their

  • psychical qualities, also got rated high on intelligence and leadership skills - a correlation

  • that seemed wrong.

  • It appears that the commanders were unable to evaluate specific traits independently

  • of others.

  • They thought of their officers in broad terms; either "good" or "bad", and allowed this general

  • feeling to influence the specific qualities they attributed to them.

  • Some officers profited from their halo.

  • Others were put at a disadvantage by what is called the horn effect.

  • The halo effect also explains why some teachers give better looking students higher grades

  • One study looked at the grades of 4,500 pupils, who were sorted by volunteers into three groups:

  • below-average, average, and above-average looking.

  • Did the better looking people get better grades?

  • The researchers then compared students' grades between classes taken in traditional classrooms

  • with those taken online where there was little to no face-to-face interaction.

  • The researchers later found evidence that students who were rated as good looking, earned

  • significantly lower grades in online courses compared to traditional classrooms where they

  • got help from their halo.

  • Since the physical attributes of good looking people seem to naturally make them also appear

  • intelligent, strong, and trustworthy, here is one good rule of thumb.

  • If you have an accident and you have to choose between two equally qualified doctors, ignore

  • their halo and choose the less handsome one.

  • He might have worked twice as hard to gain the same reputation and is likely better at

  • his job.

  • What do you think?

  • Do you think it is possible to avoid the halo effect at work, in school or in public life?

  • And what about other credentials that may signal success?
