Culture War Roundup for the week of May 19, 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.

Aristotle thought men had more teeth than women

I wonder if part of that was from the old idea that "you lose a tooth for every child". Lack of proper nutrition means the developing foetus leeches nutrients from the mother's body, and if you're an ancient empiricist and you go about counting the teeth of women of child-bearing age versus men in the same age range, it's entirely possible you might end up with "men have more teeth than women".

Childbearing has an impact on the health of women, and the impact grows with the number of times a woman has been pregnant for longer than 24 weeks. Pregnancy and breastfeeding put energy demands on a woman and can cause permanent changes to a mother’s health.

What’s less well known is the relationship between parity and oral health. That’s despite a widespread customary belief that having an increasing number of children results in tooth loss. “Gain a child, lose a tooth”, or “for every child, a tooth is lost” are common proverbs in many societies. The biological basis of these beliefs is still questioned.

There are few studies on parity and tooth loss. In addition, the available results are inconsistent. Nevertheless, increasing number of children in women has been associated with tooth loss in some populations, as seen in studies in Uganda and the US.

Yeah, there's several theories like that. It's also possible he counted including wisdom teeth - because women are statistically more likely to never have (some of) their wisdom teeth break through.

The point is, he (and his followers across the centuries) evidently never just counted the teeth (or the tooth gaps) of people.

There is also some variance in wisdom teeth: most people have 4, but other numbers happen from time to time. I know some family members of mine had only 2 or 3. More than 4 is possible too.
