Culture War Roundup for the week of April 14, 2025

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.

A blow to the CICO theory of obesity: Pre-fertilization-origin preservation of brown fat-mediated energy expenditure in humans

In mice, cold environments before pregnancy can "pre-program" fat-burning traits in offspring. Could the same be true for humans?

People conceived in colder months consistently had more active brown fat in adulthood

Cohort 4 explored energy use after eating (DIT). Again, those from the cold-fertilization group burned more calories post-meal. In Cohort 5, the DLW method showed these individuals had higher Total Energy Expenditure in daily life, even after adjusting for physical activity and body composition.

Cohort 2, which included adults of all ages, showed that cold-conceived individuals had lower body mass index, less visceral fat, and smaller waistlines. These benefits were linked to increased brown fat activity, as confirmed by structural equation modeling. Interestingly, in younger participants (Cohort 1: males aged 18–25), BMI differences were minimal, likely because they had not yet experienced age-related fat gain.

A deep dive into weather data found that lower outdoor temperatures and wider day-night temperature swings during the months before conception were the strongest predictors of adult brown fat activity.

I find this noteworthy for three reasons —

  • There’s possibly an easy and natural intervention for obesity. The Japanese neurotically dress for the weather, so how great will the effect be for those who accept the cold? “College woman walking to a party in winter wearing a short dress” was a joke when I went to school, but it was apparently pro-natal. Is it the fluctuation which is most significant? Does it need to be tied with the day-night cycle?

  • This is more evidence that humans are shockingly attuned to specific conditions they evolved in, which should be reverse-engineered to find more potentatial interventions for human flourishing. We are much more animal than we like to admit.

  • How many other “willpower problems” have less to do with willpower and more to do with 2nd and 3rd order effects which are hidden from us, or which compound invisibly? There are probably many more for obesity alone.

A) CICO necessarily follows from the Second Law of Thermodynamics, which is perhaps the most confirmed scientific theory of all time. The day you disprove it is the day physics gets really, really weird and reality as we know it ceases to make sense. So CICO is a theory in the sense that conservation of energy is a theory, which is to say it is as cold and hard of an absolute as we know to exist in the universe, no amount of obesity cheerleading will change that.

B) The effects noted in the study are frankly not that big. Like a 3% increased likelihood of active brown adipose tissue, which might increase total energy expenditure of the bodies resting metabolism of up to 5%. So conceiving in the winter gives your baby a slightly higher chance of being slightly better at burning energy, which is only a benefit if you live in a post-scarsity world.

"You eat too much and you dont exercise enough" remains the core of any and all successful diet criticism.

It is disproved on the grounds that humans are not machines, they are in fact living animals, and hunger no more obeys our will than thirst or sleep. If I ask you to voluntarily keep yourself at starvation level for an extended period of time, and offer a moderate monetary reward, you will break after a few weeks when you smell a slice of pizza or remember cookies exist. If hunger were subordinate to our will, we wouldn’t have instances of cannibalism caused by intense hunger despite the preferences of the hungry party or the threat of eternal damnation. And when you remember that modern life already requires willpower and cognitive expenditure, it’s no more surprising that the obese cave to hunger than that a thirsty person drinks sewage.

So CICO is a theory in the sense that conservation of energy is a theory

That’s not how the expression is used. The expression is used with the implication that the feasible locus of control in obesity is our willpower in regards to caloric intake.

conceiving in the winter gives your baby a slightly higher chance of being slightly better at burning energy

The significance is in the extrapolation. The takeaway is to not have babies in winter in Japan (that would be silly), but that we may be able to modify obesity significantly through pre-conception cold exposure, the limit cases of which are explored in the study. Japan is probably not even a top 100 place in the world where residents experience genuine cold for prolonged periods, due to their urban living and wealth to buy clothes.

Only if you ignore the hundreds of millions of times it has practically failed. (I have a photo of a plane with a lot of red dots to show you.)

The principal works. The problem I see with CICO is that it’s kinda like telling a drug addict that they just need to not do drugs. It’s true, the best thing a drug addict can do is not do drugs, but the advice if that is as far as it goes is precisely useless because it does tell people how to actually stop using the drugs. Better advice would include changing your routines and habits to avoid triggers and easy access to drugs, and finding things to do that fill your days with happiness without the drugs.

Food wise, the advice, in my view is to eat Whole Foods, unprocessed foods, favoring plants and protein, and limiting carbs especially simple carbs. Then you add in some exercise especially muscle building exercises though even walking has benefits.

Providing optimal advice to drug addicts is something I have neither the education nor inclination to do, but I'm still going to snort when a bunch of crackheads on Facebook or whatever start badmouthing the "drugs in drugs out theory" and telling me they get high no matter how little they smoke.
