Culture War Roundup for the week of March 11, 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.

(like the recent reports of a family in Ireland with a mutation that gives them 20 IQ points extra but causes blindness in their 20s).

thanks, interesting. Is it possible in principle to make a chimera with mutant allele in one brain hemisphere but normal allele in another?

I did some googling on ablinism and intelligence and there's some publications that say that albinism increases intelligence and/or some educational skills (might be explained by that children with albinism spend more time indoors).

In principle? Why not. Or at least I see nothing that categorically rules it out.

I don't imagine this will be easy. You would need to find a way to ensure chiral gene expression, either as an intervention in an embryo (after a certain point you know which cells are going to remain on one side) , or a more complicated deployment method if you chose to try gene therapy in an adult. Maybe you could selectively loosen the blood brain barrier in one hemisphere when you inject the vectors.

If there's a gene that works that way already that could be co-opted, I haven't heard of one, but I'm not a subject matter expert. My knowledge about mosaicism, at least in gene therapy, is when it's an unwanted consequence arising from an inability to spread the target gene to all cells.

If I had to go about this, I'd prefer finding a separate solution to the blindness or figuring out a way to prevent it from setting in in the first place instead of something so complicated.
