Small-Scale Question Sunday for June 23, 2024

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

People really, really like the idea of group selection but from an evolutionary perspective, it just doesn't seem to work out. People have tried it to model it, but it always ends up collapsing. The problem is precisely the "weeding out free-riders and the hidden sociopathic". Kin-selection does so automatically, since if you're cooperative, your relatives tend to be as well and if not vice versa. Furthermore, clan structures can and do weed out free-riders directly as well.

Btw, this does not mean that free association and broad cooperation is impossible long-term; It just means that you need to structure it in a reciprocal way so that everyone benefits.

I assume group selection works on bees and such? Are there any other society structures where it works? I was wondering if genocides could be such a selection mechanism, but it would have to be one's that do not involve taking all the women.

No, worker bees are sterile and afaik share half the genome of the queen, so serving the queen is in their direct "genetic interest". This is classic kin selection.

Is sterile the right word for something that can't reproduce sexually, but can still give birth? They start laying unfertilized drone eggs all over the place if there's no queen scent.

As you say, supporting the queen maximizes a worker's individual reproductive fitness, until there is no queen. Then it's every bee for herself.

Huh, you're clearly more knowledgeable about bees than I am. The queen suppressing the workers' reproduction with scent reminds of an argument I've heard; That, while the gay uncle hypothesis doesn't make evolutionary sense for the gay uncle himself, it does make sense for his siblings. Meaning, effectively castrating your brother so that he has to invest into your offspring is a viable strategy. It wasn't a very popular argument, however.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
