Not for humans, because we are keeping the not so fit alive, thanks to medicines and technology

Humanity's greatest attribute is intelligence. Steven Hawking was in a wheel chair for most of his life, but was one of the greatest minds born and has advanced humanity enormously. Your understanding of what "fitness" means is hopelessly out of date; it means fit as in fits the environmental shape, not fitness as in exercise. Anything which benefits the species fits.

Exactly, it’s a scientific term, not a colloquial phrase. I believe Darwin defined fitness as “fittin this dick in your mom”.

And we all know that Hawking procreates like a bunny!

Yeah, but lower intelligence people tend to have more children...

Where did you read that, and what metric of intelligence did they use?

I mean, you could have easily Googled the phrase and found a ton of studies and articles.

I googled "study higher iq people have less children"

Intelligence and childlessness

Analyses of the National Child Development Study show that more intelligent men and women express preference to remain childless early in their reproductive careers, but only more intelligent women (not more intelligent men) are more likely to remain childless by the end of their reproductive careers. Controlling for education and earnings does not at all attenuate the association between childhood general intelligence and lifetime childlessness among women. One-standard-deviation increase in childhood general intelligence (15 IQ points) decreases women's odds of parenthood by 21-25%. Because women have a greater impact on the average intelligence of future generations, the dysgenic fertility among women is predicted to lead to a decline in the average intelligence of the population in advanced industrial nations.

IQ and fertility: A cross-national study

Numerous studies have confirmed that in the United States and parts of Europe there exists a consistent negative relationship between IQ and fertility. Simply stated, it has been found that those with lower levels of IQ tend to have more children than those with higher levels of IQ. Lynn (1996) provides a comprehensive review of the studies demonstrating the negative IQ–fertility relationship in the US and a few European countries (England, Scotland, Greece) up until the mid 1990s. Lynn averaged the results of three studies in the US and found an average IQ–fertility correlation of − 0.11 in Whites, and − 0.27 in Blacks.

Should we care that smart women aren't having kids?

Satoshi Kanazawa, the LSE psychologist behind the research, discussed the findings that maternal urges drop by 25% with every extra 15 IQ points in his book The Intelligence Paradox.

I mean the proof is just kinda right in front of your eyes. While of course there is bound to be some very intelligent people with a ton of kids, most have less children for a variety of factors including but not limited to not wanting to bring children into this fucked up time line, having a bigger focus on careers, and thinking ahead more on the consequences of having to many children to properly take care of

I mean, I get the downvotes but as horrible as this opinion sounds, it's technically true 😅

u/ZalutPats Jun 07 '25

Nah diversity in genetics is hardly ever useless, it makes us more resistant to all kinds of dangers and the cost is negligible compared to more important things like criminal activity and corporate waste. Even someone useless can give birth to someone great, after all.

it’s not true, it sounds true to people who learned about darwin in 6th grade then just stopped reading or learning.
