Why did it take four years to debunk the black baby study?

'Black newborns aren’t dying at higher rates when they’re treated by white doctors.' Credit: Getty

September 18, 2024 - 8:00pm

A study published this week in a prestigious journal, Proceedings of the National Academy of Sciences, makes a claim that’s almost unheard of on the pages of leading medical journals: systemic racism and implicit bias are not the self-evident explanations for a pervasive racial disparity. To be precise: black newborns aren’t dying at higher rates when they’re treated by white doctors.

The study, conducted by a Harvard economist and a Manhattan Institute researcher, purports to debunk a widely circulated 2020 study, also published in PNAS, which concluded that black newborns attended by a white physician suffer a “mortality penalty” and are twice as likely to die. That study garnered incriminating headlines in USA Today, CNN, Science News, NPR, and The Washington Post. It was also so influential that it was cited by Supreme Court Justice Brown Jackson in the high court’s 2023 affirmative action case, in which the American Medical Association and 44 other parties declared in their amicus brief: “For high-risk Black newborns, having a Black physician is tantamount to a miracle drug.”

How could two teams of researchers look at the same data — 1.8 million childbirths in Florida between 1992 and 2015 — and reach diametrically opposite conclusions?

This time around, the researchers added one key variable that the 2020 researchers had overlooked — low birth weights — and the whole thing collapsed. The research design contained a fatal flaw, overlooking the fact that severely underweight babies, who have very high mortality rates to start with, tend to be treated by white doctors. Physicians who handle the most serious medical cases tend to see higher death rates.

It’s no exaggeration to say that this level of scholarly error raises serious questions about the hundreds of peer-reviewed studies published in the past five years that documented the prevalence of systemic racism in the medical profession and implicit bias among white doctors. Could the research design of those papers, some of which have been cited hundreds of times in subsequent papers, also have been flawed, so as to advance a progressive political agenda cloaked in the authority of objective science?

At the peak of the nation’s racial reckoning, between the years 2019 and 2021, the leading journals of the Anglosphere rushed to put out special issues and contrite reflections on anti-black racism and their journals’ institutional complicity in the brutal oppression of African Americans. Scientific American, Science, Nature, Health Affairs, and others assumed that systemic racism and implicit bias operate as natural laws which give researchers carte blanche to interpret all racial disparities as being governed by those laws.

Medical schools added lessons on critical race theory, intersectionality, identity, oppression, allyship, colonialism, patriarchy, fatphobia, power and privilege to their curricula, taking up time and space previously allotted to cell biology and anatomy. To date, more than 250 governmental bodies and private institutions have declared racism to be a public healthcare crisis, an escalation in urgency that morally justifies the prioritisation of non-whites for medical treatment, from Covid vaccinations to organ transplants, as a means to close the racial disparities gap in healthcare outcomes.

Much of the medical research of this period employs scientific terminology and statistical regression models, making it virtually impenetrable to a layperson, but the conclusions often don’t square with common sense. One study in Health Affairs concluded that neighbourhoods in New Orleans with high rates of police encounters experience significantly higher rates of smoking, poor physical health, low physical activity, violent crime and domestic violence — as if the police was the cause of these problems.

Media outlets owe it to the public to report on the latest study, rather than doubling down on advocacy journalism in the service of a monocausal moralistic metanarrative that may turn out to be flawed or even false.

The medical profession may be in for a reckoning of its own. Hundreds of peer-reviewed journal articles are ripe for an independent review that could result in corrections or possibly retractions.

This all comes back to the fact that observational studies can only show correlation, not causation, but journalists imply causation thus ignoring any confounding factor.
That the death of black babies is highly correlated with the attendance of white physicians is explained by a confounding factor that the white physicians deal with the sickest babies.
Honestly, this is year 1 statistics, but ordinary journalists are either ignorant or deliberately seek to obscure the truth.

From the paper linked in the article –

‘We posit that these differences may be ameliorated by racial concordance between the physician and newborn patient.’

Journalists often are at fault for misinterpreting correlation, but here it appears to come from the authors of the paper.

Though it’s not really a case of the statistics being wrong, just that a variable was not included originally. It is quite easy to miss a potential factor in a complicated set of data such as this.

Lol . . That’s hilarious.

Babies are weighed at birth and regularly through early infancy because their weight (and subsequent weight gain) is one of the most important indicators of their health.

Suggesting it was easy to miss is roughly the equivalent of saying that research on road traffic accidents missed data on how fast the vehicles were travelling.

I agree that intentional exclusion is much more likely than accidental oversight. There would be some consolation if this turned out to be a case of researchers (and their peer reviewers and publishers) conspiring to pervert science, but I fear it is worse.
This is likely yet another instance of the scourge of systemic anti-racism infecting the world of science. The deep faith of the devotees of this cult blinds them to their motivated reasoning and the more intelligent they are the more obdurate.
Systemic anti-racism is an established fact, and it is doing real-world damage. We have seen how the anti-racist George Floyd murder conviction and defund police campaign led to less policing and increased African American gang related violent deaths. In this instance maybe we now have more high-risk babies dying because highly experienced white doctors shied away from dealing them to avoid being accused by anti-racists of racist malpractice.

The researchers are on a mission to right perceived historical wrongs, not advance the body of scientific knowledge. A conclusion this inflammatory virtually guarantees publication, too. Where were peer reviewers in this scenario? Surely someone reviewing this paper’s conclusion should have asked about birth weight, a very basic marker for overall newborn health and vigor. Maybe the reviewers were afraid of the blowback that would result from questioning.
Result: Luxury beliefs kill infants.

It’s not that they’ve missed weight being an important factor (for the very obvious reasons you thought it necessary to point out), it’s because they’ve missed that lower weight babies were more likely to be seen by a white doctor.

Perhaps that is obvious to you, though as you’ve just demonstrated that you hadn’t realised that was what happened, I don’t think so. Even after you’ve just read an article pointing it out.

You are right in everything you say, so I am confused as to why you are being voted down.
The key point the article makes is that a flawed study design leads to flawed study results (not exactly rocket science!). The key question is why do we get so many flawed study designs these days? I believe the teaching of Critical Race Theory, which basically says racism has occurred, it is the job of the theorist to work out how it has occurred that is a big part of the problem. A subconscious bias towards creating flawed study designs? Or is it a confirmation bias thing when you get a result CRT predicts that you and your peer reviewed don’t critically analyse it and ask obvious questions like could there be another explanation? It would appear to be a combination of both.

It seems that the original study set out to prove racism, not investigate whether racism was a factor.
Sort of the opposite of “science”.
The motivations of the authors aren’t nearly as important as their methods. Did these people ever actually study science? Are they still being funded?

Because of inherent bias. Inherent bias prevents proper observation. You could call the failure to include a variable incompetence or you could point out that it was completely accurate interpretation once you start from a biased premise. So why is if biased from the jump? Its an institution injecting politics into science.

If it was so easy to spot the mistake, why did it take these authors 4 years (the article doesn’t answer the question in its own headline)? Why didn’t the reviewers spot the mistake? A more cynical interpretation might be that the authors (employed by a thinktank with a particular set of goals) spent 4 years trawling all the variables they could possibly find until they found a combination that supported their case.

The answer is the same there as it is here – if you are going up against these sick and twisted woke ideologies, then you need extreme courage and extreme diligence to make sure you are on unassailably solid ground. The woke can make all the “mistakes” they like in the name of their “greater good” but those of us who speak out against their evil will be crucified for the slightest error, including past errors that have nothing to do with the situation being exposed.

So, to summarise, White doctors (who also invented most of the medicine and medical technology that improves health outcomes for black people) take on the most difficult and risky cases and do their best to ensure black babies survive while the “diversity ” doctors take thr easy cases…..and a bunch of white liberal “researchers” decide to use bogus stats to malign those White doctors and paint them as racist.

I suppose, as a brown skinned person (and marginally more immune from being shut down by being labelled as racist), I am allowed to point out how utterly vile and disgusting this whole affair is? When and why did the West, or at least it’s academia and media, swap buzzwords and anti racism for common decency?

Only marginally “more immune.” The utterly vile racist cartoon of Priti Patel (as a sacred cow with ring through nose) that appeared in the Guardian, along with relentless media abuse of Braverman, shows that leftist media can de-victimise at will any public figure who refuses to tow their political line – whatever their colour or ethnic origin. Lampooning of Abbott or Lammy, however, is strictly off limits.

But why do “severely underweight babies […] tend to be treated by white doctors”? That is left unexplained. Is it really – as you suggest – that white doctors are keener to take on more difficult cases? Even if it is so, that itself needs explanation.

How fitting that the man often credited with saying “a lie can travel halfway around the world while the truth is still putting on its shoes” most likely did not invent the phrase.

Commonly attributed to Mark Twain, that quotation instead appears to be a descendant of a line published centuries ago by the satirist Jonathan Swift. Variants emerged and mutated over time until a modern version of the saying was popularized by a Victorian-era preacher source: quoteinvestigator.com/2014/07/13/truth

Sadly this is the tip of an iceberg, in the UK at least. A whole structure has been created with the specific purpose of creating “evidence” that BAME people are discriminated against.

Take a look at the “WRES”, which claims, for example, that BAME people are under represented at senior levels in the NHS. In fact, the official stats published by the department of health tell a different story. Amongst doctors there are 3 times more south Asians than in the general population; it’s white people who are under represented. WRES systematically distorts the evidence to reach its preconceived conclusions, and this is then used as a pretext to discriminate against white people in recruitment and promotion.

The GMC and medical royal colleges are no better. Last year the GMC published a review of performance at postgraduate exams broken down by various criteria, and claimed the data demonstrated racial bias (BAME junior doctors do not perform as well). Even a cursory review of the original data shows this conclusion is flawed. BAME students are hugely over represented at medical schools, so that the groups are not directly comparable. It’s clear that the criteria used to select entrants results in the whites who do get in being more highly selected. The largest single disparity is the proportion of students from lower socioeconomic groups ie working class white students are almost absent; the report passes over this in silence. One glaring example of the authors’ prejudices is the statement in the summary that Christian juniors do better than Muslims. In fact it’s atheists who do best and Buddhists who do worst, but that’s not the headline the authors want.

I could give many more examples, but I think this is enough for now!

I’d like to believe that a reckoning is coming, and that these dishonest bodies will be exposed, but I’m not holding my breath.

You are out of date. BAME (a senseless acronym for saying non white) has been replaced by Global Majority – an even more senseless way of saying non white. There is so much variation between all the non white groups (and withing white groups for that matter) it makes no sense to group them together. The colour of someones skin is totally irrelevant, what is relevant is the environment they were brought up in and in particular their culture. Cultures that prize and reward learning and hard work are going to do far better than cultures that don’t.

I was informed by a social justice advocate with an Oxbridge degree, that differentiating people by “culture” is dog whistle racism. Leftist doctrine teaches that cultural differences are the product of power differentials, and so even to argue that they exist is reinforcement of “white supremacy.”

That would entail that the idea that power differentials exist is itself part of “white supremacy”, and so – presumably – is an idea that should be spurned. And if power differentials do not exist, then obviously white supremacy does not exist either. So everyone’s happy.
It is one of the charms of this sort of social constructionist claptrap that it so swiftly and effectively puts cancels itself, like a suicide bomber who blows himself up before he has got within a mile of his intended target.

That’s where the racism/white supremacy bit gets in – the senior doctors are all ‘white guys’, eh? Alternatively, ‘the hospital’ (=admitting staff) is racist and makes the assumption that the white guys are best even if they’re not the senior doctors. You have to account for all this sort of thing as well as the LBW before you can rule out any element of the original claims.

There are more questions than that if we want to rule out racism in medical institutions. Such as access to and availability of services across social, economic and geographic demographics for starters. What is the percentage of babies in need who ended up in intensive care in the first place, and is that affected by race?

The capture of all formerly respected institutions and publications by critical race theory and gender theory means that the public can expect this agenda to be played for many years to come.

As a physicist, my understanding of the scientific method is to come up with a theory and then design an experiment that seeks to disprove it. Observational studies are highly prone to error as they can only deliver answers that were within the range of possible answers conceived of by the researchers. In other words, bias is almost guaranteed.
