Why did these become inversely correlated? Shouldn't smart people be having more kids?

>> No.10525672

At least in modern society, having children has no advantage and generally makes your life worse. Smart people are more likely to plan ahead and stupid people are more likely to do things impulsively and make mistakes. Particularly a stupid person is more likely to fail to use contraceptives correctly.

This isn't the case in animals. Magpies, for instance, have a positive association between task performance and reproductive success.

A Magpie isn't going to weigh the pros and cons and make a decision about making a family or not. The smartest and the dumbest are just following instinct. It's not really similar to the situation with humans where, at least these days, having children is a conscious choice. In most animals the strong instinct that results in children is to have sex. The instinct isn't to have children in and of itself. Humans have developed methods to fulfill their desire to have sex without the result that evolution "wants" (reproduction). I doubt the smart magpies would think up the idea of a condom or even be able to think of why it would be beneficial to not have children.

First you need to define intelligence but I will word it in a different and a quite simpler way. People who think more are more stressed than people who don't since thinking is an activity, just like physically exercising your body also increases your stress levels. Though there is obviously a difference in how the body handles the stress and how the body reacts to it since both activities have different goals. High stress levels correlate with thinking, its why stressed have thoughts when they try to fall asleep. Their brain is trying to solve the problems that makes them stressed, at least make them think they should not be. So yes, being stressed through thinking makes your body harder to adapt to physical activities as your brain can control your body and push it over its limits meanwhile if you exhaust your brain you have nothing to replace it with.

Earlier puberty/more pronounces sexual organs/more promiscuous sexual habits/more children/earlier time for sex/shorter lifespan/more aggression correlate with smaller brain strategy for survival.

Literally the only advantage to having children in the modern day is that they're kind of cute and fun to play with sometimes and you can build an emotional bond. They're basically just pets.
Very very expensive pets that you need to care for for 18+ years
In the distant past, people had childrens because they didn't have any way to have normal sex without getting kids or they didn't understand sex caused kids. Then people had kids on purpose because they needed them to work on the farm or care for them when they get old. Now, your kids aren't going to work for you in their childhood and you don't need kids to care for you when you're old. They're just hobbies now, and the amusement just isn't worth the hassle.

Not him but children are expensive. Even working off the assumption that you will send them to a public school and ship them to the military to reduce education/ training costs. And abort any possible pregnancy that could occur. You still have to feed them, clothed them, pay for their hygiene/ healthcare and house them for at least 18 years.

This is based off of the idea that your career allows you to stay in one home for 18 years. That said home can house more than one kid. That you don't get divorced or suffer the death of your spouse. That your kid(s) maintain decent health without getting some chronic/ semi chronic illness or weird health issue halfway through the 18 year span. That your spouse is stay at home person so you don't have to pay for babysitting or cleaning. That your kids interests/ hobby isn't expensive.

There's a lot of stipulations that need to happen to prevent children not to be expensive. More than likely the average person having a children will suffer at least 2 to 3 factors I pointed out and the likelihood of such factors only increase the more kids you have.

Anon at a population of 4 billion the top 5% alone would constitute 200 million (Japan is roughly 130 million right now). Even at 80 IQ at least 14% ( 560 million) would have +100 IQ. Half of that 280 million would have at least 107IQ or more.

Are you referencing the Flynn effect? The questions might have to be redesigned but you'd observe that general intelligence would still be very high. Given back-breaking labour and poverty I would assume a European IQ of 85-90 at that time, with something more like 108 for the landed gentry given superior genetics and living conditions.

I'm not responding to this because you don't understand normal distribution. If I were to try I would have to write an essay explaining how every sentence has 1-3 errors.

There's no reason to assume an average IQ of 80 by 2050 or 2070 (when most of population would be born). As it is I used false generous assumptions for Africans, namely a SD of 15. In actuality it's closer to around 13, so even with an average IQ of 80 we would assume only 1% of the population to have an IQ of 106. Still smaller than 1/3 of Japan's population.

>> No.10531608

>>10529701

Actually it reminds me of a quote by Murray, where he says the problem with common perception of IQ is people believe the mean to be 130 and the SD of 30.

>> No.10531612

What’s your proof that early Europeans (and humans as a whole) were dumber?

>Crabtree based this assertion on genetics. About 2,000 to 5,000 genes control human intelligence, he estimated. At the rate at which genetic mutations accumulate, Crabtree calculated that within the last 3,000 years, all of humanity has sustained at least two mutations harmful to these intellect-determining genes (and will sustain a couple more in another 3,000 years). Not every mutation will cause harm — genes come in pairs, and some weaknesses caused by mutation can be covered for by the healthy half of the pair, Crabtree wrote; but the calculation suggests that intelligence is more fragile than it seems.

>Furthermore, he argued, intelligence isn't as evolutionarily important to humans today as it was when the species was hunter-gatherers. Thousands of years ago, failing to grasp the aerodynamics of throwing a spear when a lion was coming at you meant you were toast — no more passing along your genes to offspring. Modern man rarely faces such life-or-death tests of wits, Crabtree wrote. [10 Things That Make Humans Special]

>Another theory holds that humanity's genetic capacity for intelligence is in decline because of a phenomenon called dysgenic mating. Since the mid-1800s, IQ and reproduction have been negatively correlated, studies have found. To put it bluntly, people who are more intelligent have fewer babies. Because intelligence is part genetic, some researchers argue that, if anything, IQs should be dropping.

>Development and adoption of contraceptives, obviously more likely to be used by responsible intelligent people
>Increased costs of child rearing, which discourages those with foresight
>Changes in inheritance - primogeniture inheritance means the eldest male gets everything, it doesn't matter how many kids you have. If you have shared inheritance then you split the estate and it's beneficial to have fewer children in order to give them a bigger advantage. Doesn't really apply to the poor.

>Female education and entering the workforce, obviously delays first birth. If you only have your first child at 32 you've only got a few more years to have another one. I think this is the biggest factor today.

Their population continues growing even when it hits a TFR of 2.1 because the average age is under 20. Barring famine, plague or war, it will take a long time before it reaches a steady state where the same number of people are dying as are being born. This is taken into consideration in the UN projections. This is why China is still growing despite having sub-replacement level fertility.
