WHY does the amount of hair affect a person's intelligence?

An American psychologist investigated this issue and discovered that one's level of body hair correlates positively with intelligence: the more you have, the brighter you are. 

Dr. Aikarakudi Alias claimed that doctors and highly educated persons are more likely to have chest hair in 1996. 

It is important to approach such claims with skepticism and to rely on scientific evidence rather than anecdotal observations when evaluating the relationship between different factors.
