Are racial differences obvious and important, or nonexistent?

Roboramma said:
If by "racial differences" we mean genetically inherited differences between one population and another, then yes there are. Here's one test of whether they can be called "regional differences" instead, as though they weren't genetic in nature: take a couple from population A and have it trade places with a couple from population B. Which region's characteristics will the children of those couples be seen to have?

Those characteristics which are genetically determined will be determined by their parents' genes. Given that variation within the population is greater than variation between population it would seem an unsafe prediction, insofar as it is at all meaningful, to say they would have the characteristics of any regional population. Genetic characteristics of a population are a statistical abstraction and really tell us nothing about the genetic characteristics of the individuals in couple A or B. How close to the statistical norm for their native regions are those individuals in terms of each of their myriad genetically-determined characteristics (and let's keep the example simple by allowing for the moment that there are any characteristics purely determine by genetics)? Given large enough populations in each of the regions we could perhaps find actual individuals who closely resembled the abstract genetic normal male and female for each of the population. To do so would, of course, make none of the individuals any less individuals rather than avatars of race nor the normal they resemble any less of an abstraction.

I'd say their are, and I think it's jumping the biologically-correct gun to say there arn't. If there wern't, I wouldn't have been hearing about how the Ontario police are using racial profiling for the last 3 years.

Maybe they use graphology and psychics too that wouldn't make dividing people into groups according to the way their writing slants meaningful nor would it make clairvoyance real. Just because people believe something works doesn't make it so and just because people believe something exists doesn't mean it exists.

If you want to group people according to their having dark skin (a very fuzzy parameter at best) and call those groups races you can. If you want to group people according to the colour of their eyes or the size of their feet and call those races you can do that too. It doesn't make the groups a reflection of any sort of objective reality.

I don't think you can really argue that there arn't important social racial differences in humans. At best I guess I'd call it "obvious group traits" instead of race, but it seems to me most people are willing to incorrectly use race.

I suppose what I mean is they are constructed differences, but still important and real, even if the biological difference is trivial.

Important, yes, if only as an example of our dangerous tendency to see patterns and connections where there are none. Real, though? Not just because we say it is. We need objective evidence before we can go round calling things real.
 
If race didn't matter at all, you wouldn't see people of West African ancestry consistently dominating the running events at the Olympics. (I think it's West Africa, anyway. A specific area of that continent, anyway).

Then again, if you are not an Olympic-level runner minor differences in how well you run don't matter.

The bottom line is that the differences between the human races would only matter if knowing someone's race gave you useful information about that person, and it doesn't. As others have said, overall the differences between individuals swamp the differences between races.

I'm not talking about the entire variability of the population, but those traits that can be seen to associate with one race and not another.
For instance, I don't know how many different "races" we might posit amoung austrailian aboriginees, but certainly there are traits that are common amoung all or nearly all members of that group that are not shared by any (or almost any) members of mine?
My skin is white. I have blue eyes. I don't think that can be said of any austrailian aboriginee.
Admittedly the lines are being blured as there is more and more intermarrage between races, but 1000 years ago there certainly wasn't any intermarriage between europeans and aborginees. Were they distinct then?
I won't suggest that all europeans are a "race" or that all aborginees are. I can't say where any lines should be drawn or if they should at all. I will only say that it's easy to see that there are some inherited differences between races. If you see a black man, where do you think his ancestors of three hundred years ago lived?
If there are no differences between races, if in fact there are no races, how can you make that judgement?

I'm not suggesting that these differences are anything but superficial, but that doesn't mean they don't exist.
And also, the fact that there is more variability between populations than within them doesn't mean that there is more variability amoung particular traits.

Country matters a great deal when it concerns Olympic skills. The country you refer to (Kenya, I think) does indeed dominate middle- and long-distance running, but that is not sufficient information to conclude that race is the explaining factor. Do you think race explains why countries with a lot of snow produce ski champions, and tropical countries rarely do?

Why do the same African countries not produce sprint champions, while the US and Canada do produce sprint champions from among their citizens of African ancestry?

As others have said, overall the differences between individuals swamp the differences between races.

There are a few genetic factors connected to identifiable sub-populations, but not very many. I think the tendency to sickle cell anemia is still predominant in African ancestry, and Tay-Sachs syndrome in East European jewish ancestry. But such markers are very few and none have much overall significance.
 
Why did you pose the question three very different ways before the first post?

I won't vote.

"... common among all or nearly all member of that group ...", "...almost any ...". There is the problem. If race is a matter of characteristics and it is real rather than an arbitrary grouping of people then it would seem to follow that those members of the population who did not share these "common" racial characteristics would be part of a different race (one that did have those racial characteristics). The absurd upshot of this would be that, depending on how the particular characteristics you choose a child will often not be of the same race as his/her parent. The identification of race in terms of geographical boundaries is, itself, problematic since those boundaries are arbitrary and liable to change.


My skin is white. I have blue eyes. I don't think that can be said of any austrailian aboriginee.

So are you a member of the blue-eyed race, or the white-skinned blue-eyed race. Are all the members of your family a member of this same race?

Were they distinct then?
There is nothing distinct anywhere in the concept of race.

I won't suggest that all europeans are a "race" or that all aborginees are. I can't say where any lines should be drawn or if they should at all

I suspect that the only people who could say where the lines should be drawn are those who are sufficiently prejudiced to think they can make such an arbitrary distinction and treat it as reality. Glad to see that you are not one of them.

I will only say that it's easy to see that there are some inherited differences between races.

Easy to see rarely means it's true. It's easy to see that the world is flat and that I am a solid object with no great big gaps between the sub-atomic wave-particles of which I am composed.

If there are no differences between races, if in fact there are no races, how can you make that judgement?

You can make that judgement very very badly and quite wrongly.

I'm not suggesting that these differences are anything but superficial, but that doesn't mean they don't exist.

There are differences betwen individuals. If you look for them, you can find commonalities between a group of individuals, and differences between a group of individuals. If you choose the right characteristics - let's call it Character A - you can make it appear to yourself that there is an intrinsic link between those individuals which is quite separate from the fact that you have selected characteristics in such a way as to make them appear to be a group. You can call that group a race if you like, we'll call it Race A. If you select the wrong characteristics - Character B, you'll end up with a different group of people, we'll call it Race B. The funny thing is, some of the people in Race B would have been in Race A if you had selected your group according to Character A rather than Character B. The even funnier thing is, not one of the people is changed at all by the fact that you changed their race.

True, but sickle cell anaemia is also found in individuals with no African ancestry (albeit with less frequency - limited exposure to malaria=no real evolutionary advantage) and that is not taken to imply that these disparate individuals are all members of some "sickle-cell race".

By the way, I understand that you were not intending to suggest any such simplistic conclusion, I just thought I'd steal your useful fact and use it to illustrate the arbitrariness of racial groupings. Hope you don't mind.
 
As you defined it, race is a real concept, and a useful concept in studies of anthropology, epidemiology, etc.

The idea has been laden with social and political baggage, which has no place in any society which strives to be respectful of character, merit, or ability.

The reason I used that language "nearly all", "almost any" was because there will be some members of any race who will not share every characteristic of that group. Not many. I was thinking of albinoes, for instance.
The same is true of the human species as well. If you define the difference between humans and chimpanzees as that we have a complex language, you will come across people who can't speak at all. Or mentally challenged people who's langauge is not complex. But they're still human. Why? Because they share so many other features that are also defined as human.
The same can apply to race. If you see an albino Indian, there are other features than skin colour that will point to his ancestry.



So are you a member of the blue-eyed race, or the white-skinned blue-eyed race. Are all the members of your family a member of this same race?

I am a member of a race whose members can have blue-eyes, brown-eyes, green-eyes, etc. Who are "white skinned" though there is some difference in skin tone ranging from very pale to relatively tan, none will be "black". There is a tendancy to straight hair, though some have curly hair. Maybe there are other features. I would guess that geneticists would be even more accurate at discovering someone's race than those of us who can only look at surface features.
To disprove that we can show race as a collection of features that vary across a scale, but that are nonetheless diagnostic when taken as a [whole show me one person of predominantly african ancestry with "white skin", "blue eyes" and straight hair. Or better, show me one person of predominantly asain ancestry who would be concisered african by most people who have had contact with both asians and africans in their lives.



I suspect that the only people who could say where the lines should be drawn are those who are sufficiently prejudiced to think they can make such an arbitrary distinction and treat it as reality. Glad to see that you are not one of them.

I'm not trying to suggest that there are any meaningful differences between races. But isn't this a scientific question? Your wording here seems to suggest that anyone who did "make such an arbitrary distinction" would be evil, or malicious, rather than simply wrong. And yet making that distinction doesn't suggest making a judgement about one group or another, just that those groups exist.
I don't think its a matter of morality, it's a matter of what the data says.


Easy to see rarely means it's true. It's easy to see that the world is flat and that I am a solid object with no great big gaps between the sub-atomic wave-particles of which I am composed.

Easy to see doesn't always mean true, espeically with complex issues. I agree.


You can make that judgement very very badly and quite wrongly.

What is so very very bad about my judgement that someone with dark skin of a certain hue, dark curly hair, and maybe some other features, is of predominantly african ancestry?
If you filled a room with people of predominantly european ancestry and prodominantly african ancestry, would I be able to, without prior knowledge, be able to determine the ancestry of each?
Or would anyone? Some of us might make one or two mistakes in a large sample. But we would also tend to correlate very well with each other, and with a high degree of accuracy.
How can you explain the correlation between judgements amoung any randomly chosen person if there is no valid distinction criteria?

I will now tear apart my own argument, but only a little.
My girlfriend comes from the philipines. No one would ever look at her and think she was african, european or austrailian aboriginee. But living in Hong Kong alot of people do think she's chinese, and that includes a lot of chinese. This is because she has slightly lighter skin than most filipinos. So what does that make of my argument?
Well, for one thing the closer the characteristics of two races are, the harder it will be for people to distinguish between their members, until you come to two groups that cannot be called different races at all.
But can you say that a geneticist with enough knowledge of the different gene frequencies would not be able to, with no more information than her genetic code, determine her ancestry?
I don't know the answer to that. But certainly it can be seen that she's asian. I can see it. Anyone you ask will say that she is.
And if you told them that no, actually she's european, they wouldn't beleive you. Whereas those people who at first confuse her to be chinese will not be espeically surprised if it's pointed out that she's filipino. (and her accent cannot give that away, as it's american).

I know that the differences between races are very small and pretty meaningless. But I don't see that it does any good to decide that therefore races don't exist at all.


There are differences betwen individuals. If you look for them, you can find commonalities between a group of individuals, and differences between a group of individuals. If you choose the right characteristics - let's call it Character A - you can make it appear to yourself that there is an intrinsic link between those individuals which is quite separate from the fact that you have selected characteristics in such a way as to make them appear to be a group. You can call that group a race if you like, we'll call it Race A. If you select the wrong characteristics - Character B, you'll end up with a different group of people, we'll call it Race B. The funny thing is, some of the people in Race B would have been in Race A if you had selected your group according to Character A rather than Character B. The even funnier thing is, not one of the people is changed at all by the fact that you changed their race.
But that's not how it works. Race is determined not by one single "character" but by a number of them that all coorelate rather well, and happen to fall into regional lines. Those geographic lines are blurred, because there has been interbreeding across them, but when you take two people whose ancestry was far enough apart geographically - like a norweigan and an austrailian aboriginee, that criticism no longer applies.
If you take Character A, and Character B, and Character C and you find that they all corelate very well with the members of Group A, but not Group B then if you find an individual who has character A, character B and character C that does give you some information about that individual - namely where his ancestors lived.
That's all it tells you. But that doesn't mean it doesn't tell you anything.
 
What differences are we talking about? appearance? physical capabilities? mental capabilities?

It's hard to say based on "are racial differences obvious and important, or nonexistant". Which is one reason I refuse to take the poll. What if, for instance, racial differences are obvious and existant, but unimportant? Or not obvious but important and existant. Or not obvious or important, but nonetheless existant? Or obvious but nonexistant (ie. they seem to exist but are only an illusion based on cultural differences).
Bloody false dilemas. :rolleyes:

I think that racial differences consist of mainly small differences in appearence, possibly relevent to a minor extent in physial capabiilties (but I'd need to know more about the data to make that judgement) and almost certainly not present concerning mental capabilities.

The Bell Curve: Intelligence and Class Structure
By Charles Murray

Author Charles Murray explores the ways that low intelligence, independent of social, economic, or ethnic background, lies at the root of many of our social problems. He also discusses another taboo subject: that intelligence levels differ among ethnic groups. According to the authors, only by facing up to these differences can we accurately assess the nation's problems and make realistic plans to address them.

Herrnstein and Murray argue that IQ is real; that it matters (ever so much more as society becomes more equitable and technological); that it is somewhere between 40% and 80% heritable; and that it relates to not only school performance, but to jobs, income, crime, and illegitimacy; and that it cannot be ignored in any meaningful look at America's future.

But the most explosive of The Bell Curve's arguments is that some of the difference in mean IQ scores between the white European population of the United States and the African-American population (one full standard deviation of 15 points) is probably attributable to genetic factors. No one in the field disputes this difference. The argument is over why the difference exists.

Well... that doesn't say anything about racial differences. Take an uneducated lower class white man and compare his IQ score to an upper class, univercity educated black man. The black man's score will probably be higher. Why? It isn't because of race, it's because of background.
Basically I'm saying correlation is not causation.

Herrnstein and Murray argue that IQ is real; that it matters (ever so much more as society becomes more equitable and technological); that it is somewhere between 40% and 80% heritable; and that it relates to not only school performance, but to jobs, income, crime, and illegitimacy; and that it cannot be ignored in any meaningful look at America's future.
I'm not about to deny that IQ is heritable. What I do deny is that it the genes that are meaningful to IQ are part of the varience between races.
Showing that schitsophrenia (sp?) is heritable doesn't show that it's a racial characteristic.

But the most explosive of The Bell Curve's arguments is that some of the difference in mean IQ scores between the white European population of the United States and the African-American population (one full standard deviation of 15 points) is probably attributable to genetic factors. No one in the field disputes this difference. The argument is over why the difference exists.
This is where your arguement has some force. This is also where I have to say that I simply don't know enough. I've based my opinions on things I've read, my own personal experiences with people, and an idea of how evolution works and what would be the likely divergences between races. If there is real data showing genetic differences between the IQ scores of one race and another, I'm happy to agree with you, but I haven't seen that data. I'll try to look into it.
On the other hand, I sort of doubt it at the moment. The reason I doubt it is that it seems that there are just too many other factors to control for that could bias the results. But that doesn't say it's impossible I guess.

I'll also say that even if what you're saying were true, it wouldn't mean all that much, really. Racial discrimination still wouldn't be justified. But I also think that one should look at the evidence and analyise it without preconceptions.

Do you really think that nearly all of the members of a group are going to share every characteristic of that group? That is only vaguely plausible if you pick an extremely limited number of characteristics and define them in an extremely elastic way. Look at the risible attempts which have been made to find measurable characteristics of a Jewish race, for an example.

The same is true of the human species as well. If you define the difference between humans and chimpanzees as that we have a complex language, you will come across people who can't speak at all

Which is precisely why I would not pick such an arbitrary and clearly non-definitive characteristic to identify a group.

Or mentally challenged people who's langauge is not complex. But they're still human. Why? Because they share so many other features that are also defined as human.

Then picking a feature which is neither necessary nor sufficient and which is not even a feature of every member of the group you wish to identify seems rather pointless in the first place. It is not the case that you picked a definitive feature of humans that some humans do not possess it is the case that you picked a feature that was not definitive.

The same can apply to race. If you see an albino Indian, there are other features than skin colour that will point to his ancestry.

Not necessarily so. You have perhaps heard of Grey Owl, the Englishman who earlier this century posed as a Native American very publically, even touring America and England as a Native American spokesperson for environmental issues. He was accepted as a Native American for man years both by Native Americans and the public at large. Why? Because he had the superficial features which were commonly held to be features of some Native American race. You assume a large number of differentiating features and a sharp dividing line for which there is no evidence. Even insofar as there are features which reliably point to ancestry, this does not validate the concept of race. You and I have features that point to our ancestors being shrew-like mammals but we are not shrews.

I am a member of a race whose members can have blue-eyes, brown-eyes, green-eyes, etc. Who are "white skinned" though there is some difference in skin tone ranging from very pale to relatively tan, none will be "black

A perfect example of how arbitrary and fuzzy your selection of characteristics has to be in order to assign you to a race. You say none will be "black" but that is only true in virtue of the fact that you arbitrarily define the range of skin tones identified as "black" in such a way that you can make the claim and you implicityly acknowledge that the term is elastic. Given that characteristics skip generations it would be entirely possible for you to have a child with skin colour in the range you arbitrarily call "black" (note that you even have to put quotes around your characteristics to produce a set you can use to separate your races). In fact, we don't even have to posit a dark-skinned ancestor for this (though there is no reason to suppose you don't have one), our good friend genetic mutation would allow you to have a son who produced enough melanin to have skin in your "black" range. Would it change your son's race, yours or your ancestors or would you adjust the range of skin tones you refer to as black? How many arbitrary characteristics do we have to change before your son's race is changed if you want to base it on such characteristics?



There is a tendancy to straight hair, though some have curly hair

This is even worse than compex language as a defining feature.

Maybe there are other features

And maybe they are all as arbitrary, fuzzy and open to interpretation as the features you have already listed.

I would guess that geneticists would be even more accurate at discovering someone's race than those of us who can only look at surface features

Then you would guess wrong. Geneticists can say some interesting things about ancestry (far more than can be said from surface features, certainly) but the overwhelmingly greater variation betwen individuals vs between population groups has made "race" a useless term in genetics.

show me one person of predominantly african ancestry with "white skin", "blue eyes" and straight hair

To state the obvious, go far enough back in our ancestry and we are all of predominantly african ancestry. Now I don't know enough people of predominantly African ancestry (and note how fuzzy and elastic that term is) to even begin to know whether your implicit assumption that there are no such people is correct or incorrect. I have known a dark-skinned African with blue eyes and straight-ish hair (straight hair is an abraction representing an undefined range of conformations of hair found in many diverse populations). Did she belong to your African Race purely in virtue of her dark skin? Can I put you with the Vikings in virtue of your blue eyes and white skin?

Or better, show me one person of predominantly asian ancestry who would be concisered african by most people who have had contact with both asians and africans in their lives

Why is the onus on me to provide a counter-example to your global theory that shared superficial characteristics between people imply membership of a group in any meaningful way other than that they have been selected by you, or by social convention as members of that group? Is that how we do science now? Surely the onus is on you, if it is your theory that race is real rather than a social/psychological construct, to show that "race" has predictive power beyond merely the ability of a person to conform to convention. Even if we assume that you are correct in that I will be unable to find an Asian (and Asian encompasses a huge range of variability in those superficial physical characteristics you deem to be objectively useful) it would not that the social conventions followed by your abiters of race had any objective basis.

I'm not trying to suggest that there are any meaningful differences between races

Let us ignore meaning for further discussion and stick to definitive, well defined and objective. I can't see that we should have any interest in non-definitive, ill-defined or subjective differences unless we wishe to explore the phenomena of socially constructed categories.

But isn't this a scientific question?
It should be.


Your wording here seems to suggest that anyone who did "make such an arbitrary distinction" would be evil, or malicious, rather than simply wrong.

That is not my implication. I use prejudice purely in the sense of arriving at a conclusion be prior to ascertaining evidence. That the word often has connotations of evil, rather mere wrongness, is because prejudice and evil have a relationship. It is much easier to treat people badly on the basis of prejudice than it is to do so on the basis of careful, rational consideration. That is too say the most harmful beliefs held about people tend to have no rational basis and therefore are by default examples of prejudice. There are also many, more or less harmless and morally neutral prejudices: there is no clear evil in believing that fairies live at the botom of the garden, for instance. I don't even think that all racists are evil and malicious, though it is easy to see how evil actions can arise from their beliefs. I certainly don't mean to imply that you are evil and malicious - I think it is fairly obvious that you are not - but I do think that you have started with the assumption that race exists rather than trying to determine from first principles whether it does. I disagree with you and have not, so far found your arguments compelling, though they have been worthwhile arguments. I thank you for participating in this discussion with me.



And yet making that distinction doesn't suggest making a judgement about one group or another, just that those groups exist

It doesn't entail a moral judgement but it does entail a judgement. Imagine that you had never come across the concept of race. Where would you start in your categorisation of people into groups and would you end up with the same groups you have now? Judgements will have to be made (including, possibly the judgement that there is no real advantage in constructing such groups) but what are you going to use as the basis of that judgement? I would be intrigued to hear your answers, which I am sure will be different to mine.




I don't think its a matter of morality, it's a matter of what the data says

But does the data say anything concrete? Imagine if an explanation of homeopathy, say, came back with "well it sort of works like this, I can't give you any precise data because it just doesn't work like that. Oh, and sometime it doesn't work like that but, generally it does". Do we have anything better than that for race?

What is so very very bad about my judgement that someone with dark skin of a certain hue, dark curly hair, and maybe some other features, is of predominantly african ancestry?

All of the terms to define the data from which you derive your conclusion are ill-defined (dark-skin of a certain hue, dark curly hair and maybe some other features) as is your conclusion (predominantly african ancestry - define predominant and how far back that african ancestry has to begin and end). Beyond that, you are going to be wrong some of the time because the history of our ancestors' geographical locations only points to the genetic characteristics we are most likely to have not the ones we will have.

Or would anyone? Some of us might make one or two mistakes in a large sample. But we would also tend to correlate very well with each other, and with a high degree of accuracy.

That our opinions correlate with each other very well is not particularly surprising. Socialisation ensures that our opinions correlate very well with each other on a great many things, regardless of whether are opinions are right and wrong. Lets say that you are right about the degree of accuracy with which you assess the predominant ancestry (once you have defined that term in a useful way) of your subjects , that would at most, show that there is a difference in the frequency with which certain characteristics occur in the descendants of populations of a particular region during a particular period in history (that is going to have to form at least part of your definition of predominant ancestry for the term to be meaningful). But you would still have identified no more than a trend and a social construct useful in predicting trends but which may have been misidentified as a means for producing definitive categories of people with significant differences.

Well, for one thing the closer the characteristics of two races are, the harder it will be for people to distinguish between their members, until you come to two groups that cannot be called different races at all

I respect the fact that you choose to provide a counter-example to your own argument. If I think of one to my own argument, I will do the same. Note that you used the phrase "called different races" rather than "are not different races". Does that point to an implicit acknowledgment that race is an abstract construct, or is it merely an accident of words?

But can you say that a geneticist with enough knowledge of the different gene frequencies would not be able to, with no more information than her genetic code, determine her ancestry?

I can definitely say that a geneticist cannot, with certainty, determine her ancestry. What can be provided by genetics is a good idea of her likely geographical ancestry, given sufficient information about gene frequencies by geography. They are remember, frequencies, measures of probability not of certainty. I am aware of large-scale studies in Europe with some interesting results as to the Viking ancestry of modern populations. It is I suppose pertinent to point out that despite the fact that it is possible to identify a person as being likely to have Viking ancestry, noone has seriously suggested that there was a Viking Race.

And if you told them that no, actually she's european, they wouldn't beleive you

Though, in fact, you would find many people of European, particularly eastern European descent who have Asian characteristics. Not particularly surprising considering Asia and Europe are connected and populations moved back and forth for thousands of years. What people believe is quite distinct from what is true.

I know that the differences between races are very small and pretty meaningless. But I don't see that it does any good to decide that therefore races don't exist at all

I'm still not convinced that they exist at all in any real sense. If you want redefine the term so that the sentence "my girlfriend is of an Asian race" is equivalent to "a cluster of superficial characteristics of my girlfriend are such that it is statistically likely that she had a line of ancestors originating in Asia" then we have no dispute. I'm not quite sure where that gets us though.

But that's not how it works. Race is determined not by one single "character" but by a number of them that all coorelate rather well, and happen to fall into regional lines

I'm still not convinced race is determined at all and the sort of superficial characteristics you have used - quite in line with the traditional concept of race - are so poorly defined that the determination of their presence or absence is necessarily arbitrary. If we turn to genetics, we get population genetics which gives us statistical likelihoods of particular sequences of genes in a given population rather than providing discrete characteristics that might be used in discriminating (no moral commentary intended) races.

Those geographic lines are blurred, because there has been interbreeding across them, but when you take two people whose ancestry was far enough apart geographically - like a norweigan and an austrailian aboriginee, that criticism no longer applies

There is truth in that but please recognise that Australian and Norwegian are terms of nationality rather than race and that implies a whole other are of arbitrary delineation. We could discuss caucassoid vs aborignee but these are socially defined terms - defined long before DNA was even thought of, as were all the racial categories once used in science.

To categorise somebody according to the fact that most of their ancestors lived and interbred in a certain geographical region over a certain period of time is arbitrary categorisation and furthermore represents a category which is not synonymous with race, unless we redefine the term to make it so.

To categorise them according to superficial characteristics is problematic because the types of characteristics used are necessarily fuzzy, arbitrarily selected and non-definitive. They say more about the person applying the category than the person categorised (no implied criticism, most of us are social beings as well as individuals).

To categorise them according to the fact that they have particular sequences of genes that are most likely to reflect that they had ancestors that lived and interbred in a certain geographical region over a certain period of time, represents arbitrary categorisation without even the certainty that one has picked the arbitrary category one intended to pick.

namely where his ancestors lived.
That's all it tells you. But that doesn't mean it doesn't tell you anything

If we can change that to where some of his ancestors most likely lived then we are in agreement on both counts but that doesn't make race any more real.

[But the most explosive of The Bell Curve's arguments is that some of the difference in mean IQ scores between the white European population of the United States and the African-American population (one full standard deviation of 15 points) is probably attributable to genetic factors. No one in the field disputes this difference. The argument is over why the difference exists.

The problem is that, despite the fact that they are often portrayed as a pure measure of aptitude, scores on IQ tests are influenced by preparation. Doing practice tests has been shown to make as much as 15 points in the performance of children on IQ tests. It seems entirely plausible to suggest that one's social background represents preparation of one sort of the other. It has long been accepted in psychology that there is an element of ethnocentrism in IQ test - the major IQ tests were all designed by Europeans and cultural descendants of Europeans in America and are likely to embody European preconceptions of the nature of intelligence. As far as I know, no good way to assess the degree of any such bias has been put forward which is not particularly surprising since we are all still arguing about what exactly intelligence is anyway. None of this is to say there necessarily are no such differences but it is to say that we are not even close to being able to say what they represent or why they occur. All we can say, is that those with a European-descended cultural background do better on a measure of something-or-other designed by those with a European-descended cultural background than do those not from a European-descended background.

From the point of view of "success" in modern society it may be something of a red-herring anyway. While it is true that, in general, individuals with IQs one standard deviation above the norm tend to do better in academic and income terms than those with lower IQs, as you go further up the scale the relationship breaks down. Once you get to the super-intelligent or genius range of IQ, it becomes roughly 50-50 whether the individual will do better or worse than the norm. That's my excuse for not having any money and I'm sticking to it.
 
Throg, I'd like to respond to more of this post, but well... it's really long, man! ;)
Seriously, though, you say a lot, and I don't want this to get out of hand. If there is anything that you feel is important that I didn't respond to, please point it out, though.

Which is precisely why I would not pick such an arbitrary and clearly non-definitive characteristic to identify a group.
(snip)
Then picking a feature which is neither necessary nor sufficient and which is not even a feature of every member of the group you wish to identify seems rather pointless in the first place. It is not the case that you picked a definitive feature of humans that some humans do not possess it is the case that you picked a feature that was not definitive.
Point taken. It wasn't a very good example.


Not necessarily so. You have perhaps heard of Grey Owl, the Englishman who earlier this century posed as a Native American very publically, even touring America and England as a Native American spokesperson for environmental issues. He was accepted as a Native American for man years both by Native Americans and the public at large. Why? Because he had the superficial features which were commonly held to be features of some Native American race.
Well, not that it matters, but I meant east-indian ;). Anyway, you know, I will conceed that there are likely to be members of one group that will fit into another.


You assume a large number of differentiating features and a sharp dividing line for which there is no evidence. Even insofar as there are features which reliably point to ancestry, this does not validate the concept of race. You and I have features that point to our ancestors being shrew-like mammals but we are not shrews.

Please don't take this as backpeddaling, but I think I can agree that there is not a "sharp dividing line". I do think that there are most than one differentiating features, though. But I'd also say that they fall on a continuum of frequency between one group and another. My question, which I will also admit to have explicitly accepting and now question somewhat, is this: are there any two groups whose frequencies will not overlap at all? Such that no member of one group will fit into even the lower bounds of the frequencies of the other?
I accepted this before not based on statistical evidence but based rather on things I remember having read and day to day experiences. For instance some of the examples I pointed out: "can you show me one african who has such and such characteristics" was based on my own personal experience and thus my own judging that it probably wasn't the case. Maybe I miss judged that. I'm still not sure that I did, but will conceed that just because it seems to be the case doesn't mean it is the case.
Oh, and as to the shrews, I don't like the arguement you made there because it doesn't seem to be analogous to what I was saying. We both have features that point to our ancestors being shrew like mammals, therefore our ancestors were shrew-like mammals, is more like what I was saying. Or perhaps I went one step further and said "we both have features that point to our ancestors being shrew like mammals, therefore it's likely that we have other features that we would also expect if our ancestors were shrew like mammals."
But then, if that is what I was saying, I don't think I said it very well...


A perfect example of how arbitrary and fuzzy your selection of characteristics has to be in order to assign you to a race.

But if any characteristics were completely diagnostic of a particular race, and not of another, even if each individual characteristic fell along a scale of values that might individually overlap with one other race or another, (and I'm no longer claiming this to be the case), wouldn't that then show that there was such a classification?
I mean, if we could make the differentiation, based on inherited characteristics, no matter what choise of characteristics there were, and if no member of one group were to have all the characteristics of the other, wouldn't that show that they could be called different races?


You say none will be "black" but that is only true in virtue of the fact that you arbitrarily define the range of skin tones identified as "black" in such a way that you can make the claim and you implicityly acknowledge that the term is elastic.

Well, I chose those characteristics mainly because they are what is usaully used by most people to make the distinction, and because the different races are concepts that have been around for a long time, if we were to use those concepts we should at least base them on what those races have been defined by in the past. I don't think I made the distinction abitrarily based on what I could make fit. Just on what people usually concider to be the characteristics of one group and not another.
I'm not sure that was logically incorrect. If you disagree please point out how.

In fact, we don't even have to posit a dark-skinned ancestor for this (though there is no reason to suppose you don't have one)
Agreed.
, our good friend genetic mutation would allow you to have a son who produced enough melanin to have skin in your "black" range.
again, agreed, but what are the chances of that son also having a mutation that caused his other features to fall into the range that would be classified as "african"? Not very good, I think. On the other hand maybe he would have inherited some of those characteristics from me? After all, I did point out that it's possible that he would have at least one or two of those features falling into the "african" range. So your point is taken, at least in part.

Would it change your son's race, yours or your ancestors or would you adjust the range of skin tones you refer to as black? How many arbitrary characteristics do we have to change before your son's race is changed if you want to base it on such characteristics?
I guess I was trying to say that it wouldn't be necessary. The definition could contain many features each falling along a range of frequencies. Even if one of those features fell outside of the "european" frequencies, it would require others falling into the "african" frequencies before the child would be called "african". Then again, he also wouldn't be called "european" anymore by my definition, so maybe that's not so good either. :P

Then you would guess wrong. Geneticists can say some interesting things about ancestry (far more than can be said from surface features, certainly) but the overwhelmingly greater variation betwen individuals vs between population groups has made "race" a useless term in genetics.
I know that, and pointed out that I know that. I've actually read somewhere that if you picked out two chimpanzees at random and compared the genetic varience between them with the genetic varience between, say, a native american and a zulu tribesman, there would be far more varience between the chimpanzees. I find that... well, just cool. And it certainly says something to racists who posit large differences between races. On the other hand that alone doesn't refute anyone's claims.
Nor does the fact that most varience is between individuals. If we can measure the between population varience, there must be a component that is variable between populations. And I think that component tends to be focused mainly on certain genes. That is, there could be more varience amoung certain particular genes (such as those responsible for sicle cell anemia) between populations than within populations.
Which means that even though the within population variation is more important, there might still be real differences between populations. Those differences will only be in gene frequencies, but they will still be present.

I think I should stop using the word race as it tends to suggest a strongly defined concept that someone either is or is not a part of. In that sense, I conceed the argument. I guess I did think in those terms, without really thinking about it. And reading your arguments, I can see how that position doesn't really hold up. There may (or may not) be some populations whose features could be defined such that no member of one group could fit into the other, but I can see that I can't prove that.

(snip)
that "race" has predictive power beyond merely the ability of a person to conform to convention.
I was suggesting that the concept of race has the predictive power of saying where most of a person's ancestors lived. That is a real physical prediction. I again conceed that this isn't 100% accurate, but there is certainly a statistical correlation. What I mean is that the concept can't be completely made up. How much predictive power it has is certainly up for debate, but certainly there is some degree of statistical correlation between certain features usually concidered to belong to one race and the ancestry of people who share those features?
(I use a question mark because I'm very open to any argument that says differently.

It doesn't entail a moral judgement but it does entail a judgement. Imagine that you had never come across the concept of race. Where would you start in your categorisation of people into groups and would you end up with the same groups you have now?
I would start, if I started at all, on grounds of geographic and genetic distance. Basically as any population biologist would in attempting to determine boundaries of subspecies. This is tricky in any species and homo sapiens is no exception. I think it happens quite often in biology that one scientist will call one group a "subspecies" and another will make the distiction somewhere else, based on different characteristics. So, no, I doubt I'd end up with the same groups I have now. Though it's possible that the largest groups would be the same.
This doesn't mean that the concept of the subspecies is meaningless, however. (It also doesn't mean that the concept of human races or subspecies is meaningful just because it is in other species - just that the difficulty of the question doesn't invalidate it.)

Here's an example from another species that I'll put in to spice up debate a little, though. Note that I don't know all that much about this, but what the hell.
There are two species of bird that cohabitate in northern europe. Now if you look at the populations of this bird and follow it east around the artic circle, you will notice something odd. It's features slowly change in frequency until, by the time you've come full circle you find that it is the other species. At all points around the circle any particular bird is able to breed with those living nearby. Yet when you come to the end you have two separate populations, incapable of breeding - two distinct species.
Clearly if you went say half-way around the circle (or three-quarters of the way or however far you feel necessary) you can say that these birds are part of a different subspecies than those of the original population. But any classification of subspecies will be totally arbitrary, and there will certainly be birds of one subspecies that could just as easily fit into another - maybe even better than the one they were classified under.
Does this mean that there are no different subspecies?
No. Maybe it means that the concept of subspecies isn't a very good one. Hell, even the concept of species has difficulties. But that doesn't mean that we should throw it out (I mean subspecies, not species).
Again, I point this out not because it proves that there are different races, but because I'm trying to show that the difficulty in defining exactly what a race is doesn't mean there is no such thing as race. Just that the lines aren't difinitive.
(by the way, if you disbelieve above account of the birds... I'll see if I can look it up tomorrow. It's nearly 1am and I have to be up at 6 tomorrow :) )

That our opinions correlate with each other very well is not particularly surprising. Socialisation ensures that our opinions correlate very well with each other on a great many things, regardless of whether are opinions are right and wrong.
But if our opinions are also accurate at making some prediction - such as where someone's ancestors lived, then that is surprising if they are just a social construct.

Lets say that you are right about the degree of accuracy with which you assess the predominant ancestry (once you have defined that term in a useful way) of your subjects , that would at most, show that there is a difference in the frequency with which certain characteristics occur in the descendants of populations of a particular region during a particular period in history (that is going to have to form at least part of your definition of predominant ancestry for the term to be meaningful). But you would still have identified no more than a trend and a social construct useful in predicting trends but which may have been misidentified as a means for producing definitive categories of people with significant differences.
Just thought I should say, I agree with all of the above.

Does that point to an implicit acknowledgment that race is an abstract construct, or is it merely an accident of words?
I think a little bit of both. I acknowledge that race is a social construct, I just also wonder if it caries some information. I think the boundaries that are socially accepted between races are certainly arbitrary, but that doesn't mean that everything about that concept is socially constructed.


I'm still not convinced that they exist at all in any real sense. If you want redefine the term so that the sentence "my girlfriend is of an Asian race" is equivalent to "a cluster of superficial characteristics of my girlfriend are such that it is statistically likely that she had a line of ancestors originating in Asia" then we have no dispute. I'm not quite sure where that gets us though.
Actually I think that's exactly what I'd like to do. And what that gets us is the I think true statement that there is some information carried in that concept. Not anything of social value probably, but some information nonetheless. The reason I feel it's important to acknowledge is that it if it is true it shouldn't be thrown out just because the concept has been so misused and misinterpreted over the years.

To categorise somebody according to the fact that most of their ancestors lived and interbred in a certain geographical region over a certain period of time is arbitrary categorisation and furthermore represents a category which is not synonymous with race, unless we redefine the term to make it so.
I don't recommend catagorizing individuals in that way at all, actually. I think it's often meaningless, for exampled with people of mixed ancestry (and I think most people I know are - for example of my four grandparents 2 were english, 1 hungarian and 1 ukrainian - national catagories I know, but just as an example).
I don't think though, that just because no meaningful social catagorizations can be made that means that no meaningful scientific catagorizations can be made. For instance, I think that distinct populations of homo sapiens evolved for a short period of time along similar but slightly divergent pathways due to different environments. This might have some scientific significance, but whatever differences in gene frequences did acrue while those populations were genetically distinct from each other (ie, not much interbreeding) was small enough that there is really no important social impact from that evolution. The only social consequence has been to give some relatively easy superficial qualities that make discrimination easier. I hope that stops. But that we did evolve separately for a short period of time is I think important to recognise.

If we can change that to where some of his ancestors most likely lived then we are in agreement on both counts but that doesn't make race any more real.
I think what's real is that there is some information carried by some physical features such that if someone has those features the degree of uncertainty of where his ancestors lived, what evolutionary presures they were under, etc. is decreased.
But as you've pointed out, that uncertainty does not go to zero.
So, why keep the concept of race? Well, I think I agree with you that we should not keep the traditional concept of race.
But we also should not throw out the idea that there are differences in the frequences of genes between populations that came about because of different environmental pressures.

To sum up? I think that at this point I mostly agree with you, and the rest is just semantics - should we call differences in frequencies of genes between populations "different races" or not? Well, it's a messy concept. I'm no longer sure we should. But we need to continue to recognise that those differences do exist.

PS jeez, and I said I'd keep it short. :P

Agreed. Who'd of though the question of race would get complicated? : |

are there any two groups whose frequencies will not overlap at all? Such that no member of one group will fit into even the lower bounds of the frequencies of the other?

Given the nature of genetic mutation, convergent evolution and probability I tend to doubt it.

But if any characteristics were completely diagnostic of a particular race, and not of another, even if each individual characteristic fell along a scale of values that might individually overlap with one other race or another, (and I'm no longer claiming this to be the case), wouldn't that then show that there was such a classification?

I may be misunderstanding but I think that if there was overlap with the another race then the characteristic wouldn't be diagnostic. For what it's worth it's actually really difficult to understand that question without implicitly assuming the existence of race. I'm not sure what that says about either of us?

I mean, if we could make the differentiation, based on inherited characteristics, no matter what choise of characteristics there were, and if no member of one group were to have all the characteristics of the other, wouldn't that show that they could be called different races?

Yes, I think then you would have convinced me.

I don't think I made the distinction abitrarily based on what I could make fit

I accept that but I think you did use characteristics (skin colour) that were arbitrarily chosen by tradition. I did not mean to imply that you were the originator of the tradition. My mistake.


Just on what people usually concider to be the characteristics of one group and not another. I'm not sure that was logically incorrect.

It wasn't, as I think it reflects the normal socially-defined useage of the term "race". I think the choice made it very difficult to try and establish an objective model of race but I'm not sure what else you could have done.

what are the chances of that son also having a mutation that caused his other features to fall into the range that would be classified as "african"? Not very good, I think.

Depends on what features we are going to use, of course but it's going to end up as a matter of probability which is a large part of my objection to using race as an objective category.

Which means that even though the within population variation is more important, there might still be real differences between populations

Agreed, which tells us interesting things about differntial trends between populations but I don't think it gives us anything much resembling race.

I guess I did think in those terms, without really thinking about it

We all do that about one thing or another.

That is a real physical prediction. I again conceed that this isn't 100% accurate, but there is certainly a statistical correlation. What I mean is that the concept can't be completely made up

A made-up concept can have predictive power. The old concept of phlogisten (heat as a fluid) in 19th century physics had some predictive power as did the Aristotlean model of the solar system. Both turned out to have less predictive power than better models and both seem pretty bizarre concepts today.

I think it happens quite often in biology that one scientist will call one group a "subspecies" and another will make the distiction somewhere else, based on different characteristics

I think that points out an inadequacy of the subspecies model in biology but it's really only an extension of taxonomy which was always a bit haphazard.

This doesn't mean that the concept of the subspecies is meaningless, however

Well, other than making entries in encyclopaedias neater, I'm not convinced it does have much conceptual value.


At all points around the circle any particular bird is able to breed with those living nearby. Yet when you come to the end you have two separate populations, incapable of breeding - two distinct species.

This is not something I've heard of and I am sceptical as it doesn't conform to my understanding of the mechanisms which are resposible for the inability of two species to interbreed. Do you have any idea of the name of the species concerned so I can investigate?

I think a little bit of both. I acknowledge that race is a social construct, I just also wonder if it caries some information

I am fairly sure it carries some information just not the information that it pretends to.

But we also should not throw out the idea that there are differences in the frequences of genes between populations that came about because of different environmental pressures.

Agreed.

o sum up? I think that at this point I mostly agree with you, and the rest is just semantics - should we call differences in frequencies of genes between populations "different races" or not? Well, it's a messy concept. I'm no longer sure we should. But we need to continue to recognise that those differences do exist

Yes, we should definitely continueto recognise that differene in frequencies of gene sequences exist between populations. We should just be really careful about the conclusions we draw from that information and the manner in which we relate probabilistic data to discrete data.


Thanks for a fine discussion and if you do come up with any more about thos birds could you let me know, 'cause it's going to bother me.
