The Downing effect

No longer has an article, but can be found buried in another article.

In 2008 it has an article

On 5 August 2010‎ it vanished down the Wikihole, while the Dunning-Krugers kept an article, which of course makes no sense.

Here is what was deleted

The Downing effect describes the tendency of people with below average intelligence quotients (IQs) to overestimate their intelligence, and of people with above average intelligence to underestimate their intelligence. An individual's predictable propensity to misjudge their own intelligence was first noted by C. L. Downing who conducted the first cross cultural studies on perceived intelligence.^{[citation needed]}

His studies also evidenced that an individual's ability to estimate others' intelligence accurately was proportional to their own intelligence. This means the lower the IQ score of an individual, the less capably he or she can appreciate and accurately appraise others' intelligence. The lower someone's IQ, the more likely one is to rate oneself as more intelligent than those around them. Conversely, people with a high IQ, while better at appraising others' intelligence overall, are still likely to rate people of similar intelligence to themselves as having higher IQs.

The disparity between actual IQ and perceived IQ has also been noted between genders by British psychologist Adrian Furnham. Men are prone to overestimate their intelligence by around 5 points while women are likely to underestimate their IQ by a similar proportion.^[1][2]
