It is tough to be pregnant. Get it over with! It is not easy to be pregnant. It is physically taxing and draining. Sentient females given the option may choose not to become pregnant at all. There is some thought that some phenotypic human traits (e.g. concealed ovulation) evolved to make it harder for women to predict when they would be fertile, which ...

Religion. Some fraction of Yttri society has been infected by one or more memes that boil down to "every child should live" -- and intentionally delaying birth and allowing the fetuses to eat each other amounts to murder. Not all "first world" Ytrri will think this way, of course -- but it might well be that the reduced reasoning ability of those who were ...

Frequent natural disasters, aggressive neighboring countries, plagues, short lifespan Frequent natural disasters: If there's a lot of people lost to each disaster, maybe because of severity, there's always need for mediocre people to clean up and rebuild. Few smart people to lead but many to do the job. Aggressive neighbouring countries: Training soldiers ...

Caste - only some Yttri are allowed to produce the healthier, more intelligent offspring By long-established tradition, members of the ruling caste are expected to produce only the most superior of children, while other castes are required to produce lesser, or even primitive children. Sure, there's no biological reason compelling the lowest castes to ...

Entrepreneur/industrialist driven race. May work in a part of the universe easily accessible to expansion. Multiple births over time: the leaders first - to be educated the workers in the next ones. Can be tuned in sync with the degree of intelligence required by running the business (the very late ones may even produce better specialized leaders, with ...

Voting: Rather mercenary, but if it's one being one vote, then having more kids and indoctrinating them into "your side" (whatever that might mean) would be a winning strategy. "Vote breeder" could even be a job. (And if this gets to be too unpopular, it could be banned, which means it becomes a black market job that is allowed and encouraged by those who ...

Collectivism. You don't form nuclear families if you spout a thousand young. These folks have an instinct to breed, and a strong solidarity towards society, but they don't specifically have a drive to nurture their own brood. You breed, you spawn, and they're not your kids, they're society's kids, perhaps living together in something a K-style species ...

Breeding up with the Joneses Imagine you could pick the most attractive features for your baby. Or rather, that you can produce babies until one pops out with the right combo of attractive features, then mate that one with another attractive one and make them produce a K-brood for you. This results in a strong, smart, attractive baby that you can easily ...

It depends on how extreme the intelligence difference is, and how socially advanced the country is. However, it seems really unlikely that anyone would choose full brood, in reasonably modern first world country. However, if the Yttri are a bit more pragmatic than humans, then it might make sense to stop before the "one smart one" point. We could assume ...

1: economic incentive. Just because you arent as smart does not mean you are worse off. Lower intelligence jobs might be numerous and too boring for higher intelligence people to perform. And if the high intelligence market is saturated you are better off with hard working low-intelligence. 2: long-term planning. If you get many dumb children now, those ...

Have a look at your own nieces and nephews. The glue eaters and mouthbreathers are easy to entertain. Any screen playing the latest colorful, retarded cartoon on a loop will keep them enthralled for hours so that you can go around doing your own stuff. In 2020 the latest one is Baby Shark. But the intelligent ones - you gotta keep stimulating them mentally ...

Social stratification: We can see this at work in the real world. Even in a first world country like the USA, there are millions of people in dire poverty, both rural and urban. The world the poor live in is not the same as the world of the rich. Given endemic violence, food insecurity, limited opportunities, and menial jobs, poorer Yttri might be quite ...

Your premise is a little vague on two very important sociological details: Do the individual Yttri who opt for r over K know that they are opting for r over K? Is it a conscious choice they make? Or is it more like, say, homosexuality in humans — where it clearly has implications for reproductive strategy, and yet, it's not like anyone's out there looking ...

I would say it depends, so I am going to make certain assumptions for this answer. Those assumptions being: You mean they live a REALLY long time, like 400+ years They still go into menopause at the same as as mortals If this is the case, youth might become an almost insectiod ferver of breeding. It's very sad to be 300, feeling spry, but unable to have ...

For any sentient species that isn't genetically hidebound to its ways, culture will move faster than genetics. That which is desirable and fashionable for one generation will not be for the next generation. Population preferences will shift, clan bloodlines will rise and fall in desirability, and the inheriting generation may try to push things in entirely ...

One of the main reasons Yttri still produce large broods is to further elevate the status of their favored small brood children. After all a child with a 100 siblings that are essentially servants will be able to accomplish much more than a child on his or her own. The large brood children are typically birthed first and raised/trained to care for and obey ...

Just use music. Music is murder. No wait that is not what I meant to say. Ahem. Get the rhythm from a large drum or another percussion instrument and have all the priests doing the sacrifice be at the same distance from the drum. The priest can then use the sound to synchronize. If they are in rhythm with the drum beat and they are all the same distance ...

It will be a "Handmaid's tale" world If I understand aging dynamic of your world correctly, both men and women follow traditional age trajectory with respect to their fertility, but otherwise remain perfectly healthy and strong for an indefinite amount of time. Traditional human hunters-gatherers have a fraction of elders among them. Those elders, while ...

Taxes! Their government might provide a tax break or tax credit for having more children. This alien race might want to produce more children to take advantage of the tax benefit. See https://en.wikipedia.org/wiki/Child_benefit

Eat the young "Pandora's Star" by Peter F Hamilton has a race of amoeboids on a planet with little biodiversity. They spawn in massive numbers, and the young are stupid animals, to be eaten without regard. The elders don't take any notice if the young they are eating are their own brood or others'. The young form the middle tiers of the food chain. "The ...

Gender inequality Following the example of our Terran civilization from not so long ago and still valid in most of the world. Assuming you can determine the gender of the offspring early on and assuming they would generally be of the same gender: Men are the dominant sex (gender, whatever), females are good only for domestic work, sex and reproduction. ...

Cannon fodder Having huge armies that just follows orders and don't think for themselves can be a huge benefit in warfare. Industry Quick worker assets for jobs that requires following orders and are just repetitive tasks, such as conveyor belt supply lines. As a mother that perhaps wants her children to take care of her financially you're looking at 100 ...

There could be some kind of welfare payment that increases with the number of dependent children.
