Are the Races Equally Intelligent?
by David Sims
A QUESTION from Quora: “Are all races equally intelligent?”
No. Intelligence is differently distributed among the races.
Intelligence isn’t how much you know; it is, rather, how quickly and how completely you can learn more. It’s the ability to “catch on” to circumstances from relevant information as it comes to you, bit by bit. It’s the efficiency of the mind and its biological substrate: the central nervous system’s excess capacity for abstract thinking.
Some races are smarter than others, generally speaking.
Of course, the intellectual differences between races are distributed differences. The degree of intelligence in any race’s members occurs along a normal distribution. Or, rather, the normal distribution is the familiar distribution that most nearly matches how intelligence is distributed within a race, and the reason has to do with how biological inheritance works.
The male and female gametes, at the moment of conception, each provide a random half of each parents’ genes, including the genes that code for an intelligent brain. It’s like rolling dice. If you roll only one die, you get a flat probability distribution in which each of the numbers 1 through 6 has an equal chance of showing up. But if you roll two dice, the probability distribution in the sum of the upward faces isn’t flat: it’s normal, approximately. Seven or eight is more likely than two or twelve.
That is why there’s a considerable variation in the IQs of people within the same race.
But two different races will have the genes that code for an intelligent brain at different frequencies. Not all such genes are equally efficacious, and some races have more of the “premium quality genes” for intelligence than other races do.
That is why there are considerable differences in the average IQs of races.
