IQ matters

[beew]

If intelligence (whatever that means) is inheritable, why have humans not evolved into a race of super-geniuses? Does intelligence not benefit survival and reproduction? What is the evolutionary niche for low intelligence?

I don't think it's a good analogy.

But firstly, I would argue that Mainstream theory is much less reductionistic and 'racist' (for lack of a better word) than you imply.

When Mainstream theorists claim that intelligence is partially inheritable, they don't mean it in an absolute way, since there are many other 'biological' factors at play.
Most importantly, they argue that one's intelligence is also shaped by environment: rates of stimulation, myelination and stuff, and they use twin studies (twins raised in different adoptive environments) to illustrate it.
Lastly, mainstream theorists argue that while IQ tests mostly reflect one's level of intelligence (and even so, they don't test all aspects), they also reflect the acquisition of skills required to succeed in today's society.

I would go even further than that and claim that Evolution theory is more biological-reductionistic and elitist than Mainstream theory. But that's for another time.

"self-defense"? Geezus.

I think self-defense is an apt umbrella term to cover "in the case of rape and mothers life".

Notice I didn't mention incest, that was intentional, because I'm checking my beliefs on that one. I can see the rationalization for dealing with the consequence of the unjustness in that scenario. At this point it is my belief that abortion in the case of incest falls under the umbrella of convenience, not self-defense.

4 questions for you:

1. When is a new human life created?

2. What % of abortions are because of rape?

3. What % of abortions are performed to less endanger the mother's life?

4. What % of abortions are performed for any reason other than those two?

1. Conception. Although, I would like to mind game that one out just o make sure. It seems true so I have a problem getting started with that line of questioning.
2. Probably a small amount, that even when you allow for corrections its total is still a small amount.
3. See #2 answer.
4. See #2, but large instead of small.

Are you next going to try to say that such a small amount is insignificant, so it is justified to... avoid those problems? If so, then I think you need to check your abortion beliefs against your self-defense (not umbrella usage here) beliefs.

I believe that abortion should be legal for rape. An unjust was done to them, and whatever choice the victim made would be justified.

I believe abortion should be legal for a mother who's life is endangered by the pregnancy. Whatever choice she made would be justified.

These last two beliefs cohere with my self-defense (not umbrella usage here) beliefs and they correspond with reality. They are justified.

Oh shit, check this rabbit hole!

The womb is like Plato's Cave.

A human can't develop their innate knowledge until they have senses. But you do have some senses in the cave. So my question is, when does a human develop its first singular sense? Is abstract thought a sense and what organ does it come from?

I don't think it's a good analogy.

It is the precisely correct model. Evolution is the survival of change over time. We know of heritable characteristics that survive over generations. You claim a quality or substance you label 'intelligence' is heritable. Why then don't we see its survival over time? Why hasn't 'intelligence' driven 'un-intelligence' from the genepool? Simply: How can idiot parents produce smart kids? Don't kids inherit idiocy?

I might have not have communicated well what I meant.
I was referring to probabilities, %s, as opposed to absolutes or 100%. It's possible that you were referring to the same thing.


I was having in mind (I know, not the best source) this passage from Wikipedia:

"Although the heritability of IQ for adults is between 58% and 77%,[5] (with some more-recent estimates as high as 80%[6] and 86%[7]) genome-wide association studies have so far identified only 20%-50% of the genetic variation that contributes to heritability."
https://en.wikipedia.org/wiki/Heritability_of_IQ

Which for me, in more practical layterms, translates into the following:
If you're a woman who wants IVF and is looking for an egg donor, it would be wise to opt for an egg donor with a higher rather than a lower IQ. Chances are that the offspring from the first donor will have a higher IQ than the second.

Will that guarantee it? Of course not.
As the quoted stats. provided by geneticists suggests, Heritability is only part of the Biological lottery. Evolution is probably part of that lottery too.

What would be the driver for evolving a higher IQ range?

I wanna give the answer a try!


Gaining knowledge through trial and error.
Or put another way.
Learning from our mistakes and discoveries.

This is why it is important not to remove the risk vs reward decisions that humans need to make to evolve.

Knowledge isn't intelligence. Knowledge is passed down from everyone to everyone. Your IQ won't go up just because someone figures something out and now we all do it.
Intelligence is knowing how to apply the knowledge not gaining the knowledge.

I disagree.


in·tel·li·gence
inˈteləjəns
noun
1.
the ability to acquire and apply knowledge and skills.

My mother-in-law was Mensa eligible and one of the most ignorant people I've ever met. No social skills and no ability to use knowledge for anything but her attempts to look down her ugly nose at others.

Brain size is inheritable. Brain size has a bearing on intelligence, although it is not a precise indicator.

Brain size has been limited in humans by the size of the female pelvis. The limit might have been reached now, and larger-brained children may never be in our future. There are also many hurdles to cross in brain development from fetus to adult, and intelligence gets suppressed by environmental conditions.

So maybe we are already as intelligent as it's possible for a species to be.

Not so much brain size as brain diameter.

But what drives it higher than the level required to survive?
