[edit] NPOV

I would argue that this image is trying to put forwards a POV and is therefore not NPOV. For example, no explanation is made to explain what is meant by black or white, and therefore it is unclear what the information in the graph is portraying. --Rebroad 23:16, 21 January 2007 (UTC)

[edit] Inaccuracy

This graph is inaccurate blacks have an IQ of 85 with 13.0 standard deviation and whites have an IQ of 100 with 15.0 standard deviation. This suggests that blacks have a smaller variance in intelligence, thus more the IQ rises from the Flynn effect, the greater black-white difference.

Genetically intelligent people vary more in intelligence than the less intelligent counterparts. To see why it is, here is an hypothetic example: Chimpanzees will always score 40 on an IQ test while humans score 100 on an IQ test. Humans vary from IQ of 40 to 160.

But do you every see a chimpanzee vary that much (sixty points higher or lower)? Do chimpanzees have IQs that vary from 0 to 100? Is the number of chimpanzees that have an IQ of 100 and number of humans that have an IQ of 160 the same? Of course not.

You cannot compare the variance between less intelligent animals and more intelligent animals.

Another example: There are tall blue whales. There are also tall blue whales that are a few meters shorter than the last tall blue whale. The standard deviation in height between blue whales are a few meters. But applying it to bugs will get unreasonable results. Do bugs have a standard deviation of a few meters? Do you ever see a three meter bug?

Comparing intelligence has to be done in a proportional way. The smaller the object, the less its variance.

It is reasonable to suggest that less intelligent groups of humans have a smaller standard deviation.
