When you're deciding what to replace X with in the following statement, it most certainly does matter:

"X have a lower IQ on average."

You can choose "People of African descent" or you can choose "People from poor backgrounds" or "People with serious health conditions" or "People with drug addictions" or any number of other things.

When attempting to determine how best to help a school in a black ghetto that is failing, and you're choosing between spending money on remedial courses or on a school nutrition program, you will most certainly benefit from having this knowledge.

Conversely, I can't think of any applications for which tying IQ to race is useful. Would you name three examples?

Also, I'm still interested in seeing the source that you believe is an accurate prior regarding race and IQ. Do you happen to have that information available?

Well, seeing an unknown man approaching you at night, granted this is more about criminality than IQ but the correlation is the same.

Also thinking about whether affirmative action and the desperate impact doctrine are reasonable ideas.

4Muhd7yIf the results of the racial IQ studies are true, then that is very important because it disproves the doctrine of ethnic cognitive equality. Many people, especially in America, have this idea that all ethnic groups must have exactly equal average cognitive ability, and that if one or more ethnic groups perform below average on a test of aptitude, that is taken as strong evidence that the test is invalid and racially biased and thus cannot be used. For this reason, many aptitude tests are severely restricted in their use since they are considered racist. This in turn would have a negative economic impact if these tests are actually valid, since employers and colleges are forced to use other, less effective means to vet candidates.
2Jiro7yYou might be in a situation where you need to decide how to allocate money to help a black school or a white school. If white people have higher IQs, and if money is worse at improving the performance of students who do poorly because of IQ than it is at improving the performance of students who do poorly for other reasons, then you should allocate the money to the white school. You might be in a situation where you need to hire a white person or a black person and have no information about their IQs, but you would prefer an employee with a higher IQ. You then should hire the white person. Of course, this is exactly why using IQ this way is a bad idea.

Why Are Individual IQ Differences OK?

Idang Alibi of Abuja, Nigeria writes on the James Watson affair:

A few days ago, the Nobel Laureate, Dr. James Watson, made a remark that is now generating worldwide uproar, especially among blacks.  He said what to me looks like a self-evident truth.  He told The Sunday Times of London in an interview that in his humble opinion, black people are less intelligent than the White people...

An intriguing opening.  Is Idang Alibi about to take a position on the real heart of the uproar?

I do not know what constitutes intelligence.  I leave that to our so-called scholars.  But I do know that in terms of organising society for the benefit of the people living in it, we blacks have not shown any intelligence in that direction at all.  I am so ashamed of this and sometimes feel that I ought to have belonged to another race...

Darn, it's just a lecture on personal and national responsibility.  Of course, for African nationals, taking responsibility for their country's problems is the most productive attitude regardless.  But it doesn't engage with the controversies that got Watson fired.

Later in the article came this:

As I write this, I do so with great pains in my heart because I know that God has given intelligence in equal measure to all his children irrespective of the colour of their skin.

This intrigued me for two reasons:  First, I'm always on the lookout for yet another case of theology making a falsifiable experimental prediction.  And second, the prediction follows obviously if God is just, but what does skin colour have to do with it at all?

A great deal has already been said about the Watson affair, and I suspect that in most respects I have little to contribute that has not been said before.

But why is it that the rest of the world seems to think that individual genetic differences are okay, whereas racial genetic differences in intelligence are not?  Am I the only one who's every bit as horrified by the proposition that there's any way whatsoever to be screwed before you even start, whether it's genes or lead-based paint or Down's Syndrome?  What difference does skin colour make?  At all?

This is only half a rhetorical question.  Race adds extra controversy to anything; in that sense, it's obvious what difference skin colour makes politically.  However, just because this attitude is common, should not cause us to overlook its insanity.  Some kind of different psychological processing is taking place around individually-unfair intelligence distributions, and group-unfair intelligence distributions.

So, in defiance of this psychological difference, and in defiance of politics, let me point out that a group injustice has no existence apart from injustice to individuals.  It's individuals who have brains to experience suffering.  It's individuals who deserve, and often don't get, a fair chance at life.  If God has not given intelligence in equal measure to all his children, God stands convicted of a crime against humanity, period.  Skin colour has nothing to do with it, nothing at all.

And I don't think there's any serious scholar of intelligence who disputes that God has been definitively shown to be most terribly unfair.  Never mind the airtight case that intelligence has a hereditary genetic component among individuals; if you think that being born with Down's Syndrome doesn't impact life outcomes, then you are on crack.  What about lead-based paint?  Does it not count, because parents theoretically could have prevented it but didn't?  In the beginning no one knew that it was damaging.  How is it just for such a tiny mistake to have such huge, irrevocable consequences?  And regardless, would not a just God damn us for only our own choices?  Kids don't choose to live in apartments with lead-based paint.

So much for God being "just", unless you count the people whom God has just screwed over.  Maybe that's part of the fuel in the burning controversy - that people do realize, on some level, the implications for religion.  They can rationalize away the implications of a child born with no legs, but not a child born with no possibility of ever understanding calculus.  But then this doesn't help explain the original observation, which is that people, for some odd reason, think that adding race makes it worse somehow.

And why is my own perspective, apparently, unusual?  Perhaps because I also think that intelligence deficits will be fixable given sufficiently advanced technology, biotech or nanotech.  When truly huge horrors are believed unfixable, the mind's eye tends to just skip over the hideous unfairness - for much the same reason you don't deliberately rest your hand on a hot stoveburner; it hurts.
