Culture War Roundup for the week of October 14, 2024

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Well it looks like embryo selection for IQ is here.

A US startup, using data from the UK Biobank, is offering embryo selection for “IQ and the other naughty traits that everybody wants”, including sex, height, risk of obesity and risk of mental illness.

What surprises me most about this is that they were able to use the Biobank data, and that the head of the Biobank is defending its use. The Biobank is, as I understand, the world's best source of genetic data and I had always hoped that it would be used for this kind of liberal eugenics. However I'd assumed that doing so would be hampered by 'bioethicists' or at least the default political caution of these kind of institutions. However, the head of the Biobank seems to...think this is good?

UK Biobank … has confirmed that its analyses of our data have been used solely for their approved purpose to generate genetic risk scores for particular conditions, and are exploring the use of their findings for preimplantation screening in accordance with relevant regulation in the US where Heliospect is based. This is entirely consistent with our access conditions. By making data available, UK Biobank is allowing discoveries to emerge that would not otherwise have been possible, saving lives and preventing disability and misery.

Well that's a pleasant surprise. I guess I shouldn't be too shocked that the head of a massive genetics project actually understands the implications of his scientific field, but it's great to have my default cynicism proven wrong.

The quotes from the 'bioethicists' are maddening, of course:

Dagan Wells, a professor of reproductive genetics at University of Oxford, asked: “Is this a test too far, do we really want it? It feels to me that this is a debate that the public has not really had an opportunity to fully engage in at this point.”

Not an argument, he's just vaguely gesturing at the implication that it might be bad. It's also unclear why, in a context where IVF is already legal and accepted by almost everyone, this needs to be subject to a public debate. This is just IVF with more informed choices over which embryo to implant.

Katie Hasson, associate director of the Center for Genetics and Society, in California, said: “One of the biggest problems is that it normalises this idea of ‘superior’ and ‘inferior’ genetics.” The rollout of such technologies, she said, “reinforces the belief that inequality comes from biology rather than social causes”.

Translation: This scientific advance is bad because it reminds people of facts which I am politically uncomfortable with.

If being slim, happy, kind, law-abiding, rich or intelligent is better than being fat, depressed, cruel, criminal, poor or stupid, and if these things are affected by genetics (which they are) then there is such a thing as superior or inferior genetics.

Either Ms Hasson believes that genes don't influence anything (in which case she should not be working at a centre for genetics) or she believes that all human characteristics are equally good (in which case she should not use the term 'ethicist' in her title). Or perhaps she is a bioethicist who believes in neither biology nor ethics.

By late 2023, the founders of Heliospect claimed to have already analysed and helped select embryos for five couples, which had subsequently been implanted through IVF. “There are babies on the way,”

This is probably the most important part in my mind. It will be extremely hard to argue against embryo selection when there are happy, healthy, intelligent children running around. In the same way that skepticism around IVF vanished as the first IVF babies grew up, there will one day be embryo-selected adults giving interviews on TV, eloquently defending it.

Tiger mothers of the world, rejoice. You can now give your kids a heads-up that actually works, and doesn't require you driving them to extra-curriculars all the time.

It's a very minor gain, and IVF vs in-vitro probably offsets its already. When they can do at-home sperm selection, then I can expect this to take off. But as far as I understand, the test is a destructive process: you gather several eggs, then conception happens, the embryos grow a bit till the can survive some of their cells being removed, these cells are grown into a culture and tested, then the best embryo is implanted and the rest destroyed. You can't just ejaculate through a magic device that filters out inferior gametes.

If you do this test on a regular embryo, it starts looking too much like an abortion (which it technically is already).

the best embryo is implanted and the rest destroyed

Not true. The rest are frozen and saved for later. And "later" is often pretty soon, because each embryo transfer has a pretty high chance of failure.

Possibly they are destroyed at some point if they are no longer wanted. But in general, the challenge with IVF is having too few embryos, not too many.
