It is also sometimes called the halo error. == History == The halo effect was first introduced in 1920 by [[Edward Thorndike]]. It was used to describe how thoughts about one part of something can change how other parts of that thing are seen. An example is how good someone looks can make people think that the person is good at other things just because they look good. When the halo effect is talked about it is mostly used to talk about how it affects people, but it can be used for things like companies or people of a country <ref>Leuthesser, L., Kohli, C.S. and Harich, K.R.
