Scientists continue to look for some biological evidence of intelligence, somehow some peoples genes are better than others. Pseudo scientists have gone as far as saying some races are pre disposed to superior intelligence, obviously that means they should determine the direction of the world as they are the more intelligent.
However real scientists can not find evidence of a gene that makes anybody more intelligent. Reading this article from scientific American shows that there are many factors at play. At best we are all just humans who have different interests and become good at those interests. In the West of course they are pre disposed too saying they are the most intelligent, but science does not back them up, maybe people should re-watch “My Fair Lady” again, things are just about being taught, necessary to be thought in a certain direction often. Relax we are all just humans, there will be no gene that one will find saying this race is more intelligent than the other, lie with your IQ tests but the gene the real evidence will never be found.
