Upvoted, but... it looks like the kind of shiny clever idea nerds love and that blows up in their faces big time. "Purely factual questions discussed separately from ethics" sounds like something Paul Graham would pat you on the back for. Specific instances thereof, such as "Do people have more sex if they ignore body language expressing discomfort?" are significantly less tasteful.

The problem is that this is a public forum. In our ivory towers - inside our own heads, and with other people who like to toy with weird ideas - we can totally argue that genocide is legitimate if there's a genetic disorder spreading whose carriers only have male children with the disorder. But we don't expect it to be harmless to discuss that in front of the neonazis (or even ourselves, really). There are people I don't want looking at a factual discussion of how to get away with rape.

My cursor was literally hovering over the upvote button from the first paragraph on... and then I got to the last sentence, which completely reversed my view of it. Then I went back and parsed it more carefully, and now it looks to me like there's some pretty sketchy rhetoric in there.

Specifically: there's mindkilling ideas and then there's ideas which represent a physical propagation risk, and while PUA is undoubtedly the former, framing it with rape and genocide implies the latter. Now, I suppose it might look like that to some of its more extreme opponents, those who see it as not just squicky or disrespectful but actively dangerous. But that's not the consensus, and there are substantial differences in the way we should be approaching it if it was.

On the other hand, if you'd cast your objection in terms of signaling or associational problems, I'd be right there with you. I'm pretty much neutral on PUA as such, but it's an incredibly polarizing topic, and this isn't a big enough site that we can discuss stuff that volatile in public and expect it not to reflect substantially on the site as a whole.

For onlookers wondering about the genetic disorder thing, it was discussed in Evolving to Extinction. The relevant part:

Segregation-distorters subvert the mechanisms that usually guarantee fairness of sexual reproduction. For example, there is a segregation-distorter on the male sex chromosome of some mice which causes only male children to be born, all carrying the segregation-distorter. Then these males impregnate females, who give birth to only male children, and so on. You might cry "This is cheating!" but that's a human perspective; the reproductive fitness of this allele is extremely high, since it produces twice as many copies of itself in the succeeding generation as its nonmutant alternative. Even as females become rarer and rarer, males carrying this gene are no less likely to mate than any other male, and so the segregation-distorter remains twice as fit as its alternative allele.

It just occurred to me that such a situation can rectify itself without the need for genocide :-) If females can detect males carrying the segregation-distorter, they will avoid mating with such males, because having female children is a reproductive advantage in a population where males outnumber females. Or am I getting confused again?

There would also be strong selective pressure for any genes which can override the segregation-distorter, even if the females can't recognize the males which carry it.

A modest proposal:

If mothers made a habit of snacking on (each other's) litters of all sons, that would counteract the problem. That wouldn't require being able to differentiate among adult males, just between male and female children.

If the species takes a long time to wean children and doesn't reproduce until that process ends, this works better.

Mice, pigs, rabbits etc. (animals with large litters) already eat weak children fairly often, so this is somewhat plausible.

I love lesswrong!

Rather than rely on females recognizing things about males, what about genes that capitalize on the difference between regular males and those with the disorder - sisters!

Females could more greatly than presently value aggression (this would only need a boost, the trait already exists), and a gene could make females intervene to break up their brothers' fights. Young males with the disorder would tear each other to shreds or be too timid to reproduce, and males without the disorder would have sisters preventing them from killing each other.

"Strong" for sure. Unfortunately for the species it would have to emerge fully functional in the time it takes for the species to evolve to extinction. Not so easy.

Nice!

Now I wonder why Eliezer's post calls the original problem unsolved. Surely such elementary solutions couldn't have evaded the experts in the field? I'm guessing that I made a mistake somewhere...

Unfortunately, this will only work in a population with a weak segregation distorter. Remember, mutations that do a specific thing are rare, and detecting the presence of a specific allele that doesn't have large-scale phenotypic effects is tough. By the time the segregation distorting allele is a large fraction of the population it is almost too late for the population.

It seems easier to evolve a preference for incest.

Do people have more sex if they ignore body language expressing discomfort?

Almost certainly not! That's valuable information needed to calibrate optimal seduction technique, even for a PUA of perfect soullessness.
