Why Are Individual IQ Differences OK?

This reads like a classic case of motivated cognition.

Did you stop to make distinction between me being influenced by motivated cognition and alternate explanations like:

  1. Me seeing significant flaws in data that would otherwise support your conclusion. Part of this may be that I've spent a significant amount of time reading about IQ and giftedness and I have learned that there are a lot of pitfalls to doing IQ related research.

  2. Me simply being unaware of relevant data. (This might be the case in the event that the people who supplied my data were in

I don't see a good way to tell the difference between a low IQ score due to actually being less intelligent versus a low IQ score due to nurture-related reasons such as the following:

As the saying goes, "Life is an IQ test." The predictive ability of IQ on income (and most other statistics of interest) is very similar for each race, which suggests that differences in measured IQ scores map onto differences in life outcomes. To the extent that a medical condition makes someone test poorly, it generally also makes them live poorly. (There are a ...

-1Eugine_Nier6yIf your point is that it's not clear to what extent the difference in intelligence is due to nature or nurture, I agree but would like to point out that for many applications it doesn't matter.
2Lumifer6yIn Africa? It so happens that the world is much bigger than the USA and the people in sub-Saharan Africa test for IQ pretty much the same as African-Americans. Sure, you can control for wealth/economic status. Or you can go and test poor peasants in China and poor peasants in Africa. You seem to think that this is a white-vs-black US problem. It's not. The highest-average-IQ large group of people is East Asians, like Han Chinese -- not Caucasian whites. I am curious -- how do you figure out that in a distribution close to normal only 25% are higher than the mean?

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.
