To the guy who required citation for the sentence "The result is somewhat similar to the placebo effect": dude, please lookup "placebo effect" first. Here is a fairly good description. —Preceding unsigned comment added by 93.123.21.134 (talk) 08:36, 7 September 2010 (UTC)[reply]

For example, a teacher may have a favorite student because they are biased by in-group favoritism. The teacher ignores the student's poor attainment. Conversely, they might not notice the progress of their least favorite student.

I question whether this is an appropriate level of focus on flaws in the educational system. Quite apart from selective perception, nobody ever attains a fully balanced, calibrated opinion on a room full of thirty people—even more so when the domain of interaction is narrow and prescribed.

How about an example of selective perception centered around the balanced interplay of an extended-family Thanksgiving dinner with 30 plates served? In which no-one has a favourite or disfavourite uncle. — MaxEnt 18:34, 11 January 2019 (UTC)[reply]

Seems to be redundant with selection bias, there also are other similar articles. —PaleoNeonate – 19:47, 31 January 2020 (UTC)[reply]
