Yes, some anatomical differences are certainly affected by environment, but the quoted phrase is typically used in the context of treating races differently based on behavior ("X people are immoral", "Y people are stupid"). It's meant to encourage people to treat each other with equity and consider that such observed differences may be distorted by news, your like-minded cohorts, sociological conditions, etc, which are all theoretically addressable. But maybe I'm misunderstanding your question, since clearly the idea that races have anatomical differences is not contested by anybody - after all, anatomical difference is the very thing we base the word "race" on, colloquially. You don't need non-obvious differences to see that, since we already have obvious differences.

This is not true. I had a college professor explain the "race is a social construct" idea, and her position was staunchly that there was _no_ biological basis for race. See also this article by the scientific american[1]:

> Today, the mainstream belief among scientists is that race is a social construct without biological meaning.

This is the idea that GP is responding to - clearly there must be some biological basis for race, if an AI can determine race from an x-ray.

Not necessarily; they could easily reflect societal differences. Bone density could be affected by diet, or medical care received, or environmental factors in poor neighborhoods, which might easily vary by race without there being a genetic cause for that variance.

If it were a simple "all black people have a bone density of 3; all white people have a bone density of 2" you could pretty solidly conclude a biological component, but we're in the realm of small variances and probabilities that confound things quite a bit.

I think the most likely explanation for these results is something like https://techcrunch.com/2018/12/31/this-clever-ai-hid-data-fr..., personally. Especially with the 8x8 pixelation example.

I'm not sure how your link applies to this situation. That refers to an interesting way an AI encoded data in an image. The issue here is that this data _exists in the first place_. Whether the AI learned to compress the racial data into an 8x8 picture is besides the point.

The point is “the AI might not be doing what you think it is doing, because it doesn’t actually understand the goal”.

You're misunderstanding the context of the thread. At this point in the thread, we're talking about whether or not there is any biological basis for race, not about the AI example in particular. The premise here is that there is a biological basis--that race is a label applied to a cluster of genetic traits (various facial shape features, skin color, etc) which are almost certainly genetically constructed.
Re:AI Recognises Race in Medical Images by ceejayoz on Tuesday September 14, 2021 @12:26PM (#28527136)
The comment I replied to stated "clearly there must be some biological basis for race, if an AI can determine race from an x-ray".

I'm pointing out that's not necessarily true. First, we have to prove that the AI is determining race from an x-ray. It's effectiveness at doing it via 64 pixels makes me skeptical that it is.

After that, we get into sticky territory determining whether any biological differences we can identify between races are caused by genetics, or environmental/societal factors like disparities in healthcare, diet, neighborhoods built over old SuperFund sites (https://en.wikipedia.org/wiki/Love_Canal), etc.

Re:AI Recognises Race in Medical Images by notahacker on Tuesday September 14, 2021 @09:35AM (#28524568)
There is a massive difference between there being a biological basis to some of the phenotypes associated with racial categories and there being "biological meaning" to identifying races.

"Black" represents a wide range of genotypes, many which differ more from each other than from "white" individuals and populations, even if there may be other tendencies like bone density and novel genetic features that appear more commonly or exclusively in some subsets of the "black" population. The skin colour phenotype being (usually) darker just happens to be very easy to notice and have acquired a lot of socially constructed meaning. Except in the narrow context of skin tones, it isn't biologically meaningful to consider "black" people as a particular group though, particularly not compared to more specific genetic markers that don't have the same socially constructed meaning...

Re:AI Recognises Race in Medical Images by foldr on Tuesday September 14, 2021 @09:38AM (#28524600)
The point of the article is that if you clustered people based on genetic or anatomical properties in a non-post-hoc way, you would not end up with the same system of racial categories that are commonly used in the USA (or indeed any other country). As another poster has pointed out, the most striking example of this is the category 'Latino', which while often treated as a 'racial' category obviously has no biological basis.

This does not entail that no biological traits are correlated with race – biological traits are correlated to varying degrees with all kinds of subgroups of people. It does, however, mean that racial categories have no scientific basis.

To expand on this, imagine a Martian scientist studying human biology in isolation from human culture. Such a scientist would not subdivide humans into groups that match common racial categories, as these groupings are arbitrary from a biological point of view.

The idea that races have anatomical differences is very much contested, and rightly so.

That article writes about very specific ethnicities with shared ancestry. Race is something entirely different.

That’s what the study calls into question.
Re:AI Recognises Race in Medical Images by tpm on Tuesday September 14, 2021 @01:27PM (#28527932)
More often than not, AI/ML finds some surprising shortcut. I am pretty sure this will be the case too, because "races" and their (hypothetical) biological or genetic foundations don't map at all.
Re:AI Recognises Race in Medical Images by zepto on Tuesday September 14, 2021 @01:39PM (#28528081)
I would like to agree with that, since I would like to believe race is a construct that we can dispense with at some point.

That said, assuming the paper is just wrong is simply bias.

If there is an identity associated with race, there is no reason to think it doesn’t impact biology. There is no reason to assume it’s genetic.

Re:AI Recognises Race in Medical Images by tpm on Tuesday September 14, 2021 @02:28PM (#28528773)
Well if race has biological basis and also if race is inherited, there is no way around a genetic basis. Also there is a more than hundred year history of scientific research and no genetic (or other) grounding for race has been found. So yes, that is the source of my bias.

False. Diet and behavior affect biology amongst other things.

We didn’t have machine learning or big data 100 years ago.

Yeah, so if a South-Asian orphan is adopted into a Swedish family, he magically ceases to be of whatever race were his parents and becomes white. That's... not how the concept of human race works.

Re:AI Recognises Race in Medical Images by zepto on Tuesday September 14, 2021 @08:44PM (#28533603)
According to many proponents of CRT or wokeness, absolutely he becomes white. People from typically non-white ethnicities are routinely accused of being white if they adopt cultural traits associated with white people.

And it’s entirely possible that if he was adopted at a young enough age, whatever this AI is detecting would read him as white too, assuming his habits and diet affected his development, as they might.

Indeed that would be consistent with your claim that there is nothing genetic about race.

Do you think that racism is real?
Re:AI Recognises Race in Medical Images by tpm on Wednesday September 15, 2021 @02:19PM (#28542477)
Yes, racism is sadly very real, it is based on perceived ingroup/outgroup differences and as such is only one of such ideologies (I come from a territory where people used to kill each other if they belonged to different branches of christianity, or later if they belonged to different nationality). They are all based on false beliefs and propagated by people who are trying to profit from hate and conflict.
