The question of hereditary and acquired nature of intelligence

The first bit of research I looked into in an attempt to get a clear answer to this question was a study involving identical twins and if they share the same amount of intelligence. Identical twins have percent shared DNA, so their intelligence levels are very similar. A study shows that even when raised in separate households, the identical twins still have extremely similar IQ levels, which means we can gather that genetics holds more weight on the intelligence scale than where one was raised, but environment is still a key factor. Fraternal twins are different.

The question of hereditary and acquired nature of intelligence

It goes a bit back in your discussion, but what I should like to know, Mr. In that case, you could perhaps connect this with the ideas of Mr. Well, I think that as a matter of biological and anthropological fact, the nature of human intelligence certainly has not changed in any substantial way, at least since the seventeenth century, or probably since Cro-Magnon man.

And as those conditions change, a given human intelligence will progress to new forms of creation. In fact this relates very closely to the last question that Mr.

Elders put, if I can perhaps say a word about that. Take behavioural science, and think of it in these contexts. It seems to me that the fundamental property of behaviourism, which is in a way suggested by the odd term behavioural science, is that it is a negation of the possibility of developing a scientific theory.

That is, what defines behaviourism is the very curious and self-destructive assumption that you are not permitted to create an interesting theory.

If physics, for example, had made the assumption that you have to keep to phenomena and their arrangement and such things, we would be doing Babylonian astronomy today.

Fortunately physicists never made this ridiculous, extraneous assumption, which has its own historical reasons and had to do with all sorts of curious facts about the historical context in which behaviourism evolved. But looking at it purely intellectually, behaviourism is the arbitrary insistence that one must not create a scientific theory of human behaviour; rather one must deal directly with phenomena and their interrelation, and no more something which is totally impossible in any other domain, and I assume impossible in the domain of human intelligence or human behaviour as well.

Here is a case in point of just the kind of thing that you mentioned and that Mr. Well, it has long since run its course, I think.

"Heritability" is defined as the proportion of variance in a trait which is attributable to genetic variation within a defined population in a specific environment. Heritability takes a value ranging from 0 to 1; a heritability of 1 indicates that all variation in the trait in question is genetic in origin and a heritability of 0 indicates that none of the variation is .

It's a difficult question to answer but at least slightly easier than "how much of character and personality is genetic ".Intelligence is mostly genetic but needs a conducive environment to grow in the right of course you have to define intelligence first. INTRODUCTION. The special subject of the greater part of the letters and essays of Schiller contained in this volume is Aesthetics; and before passing to any remarks on his treatment of the subject it will be useful to offer a few observations on the nature of this topic, and on its treatment by the philosophical spirit of different ages.

Whatever value it may have had init has no function today except constraining and limiting scientific inquiry and should therefore simply be dispensed with, in the same way one would dispense with a physicist who said: One forgets about that and puts it aside.

Similarly one should put aside the very curious restrictions that define behaviourism; restrictions which are, as I said before, very much suggested by the term behavioural science itself.

We can agree, perhaps, that behaviour in some broad sense constitutes the data for the science of man. But to define a science by its data would be to define physics as the theory of meter-readings. And if a physicist were to say: And so the term itself is symptomatic of the disease in this case.

We should understand the historical context in which these curious limitations developed, and having understood them, I believe, discard them and proceed in the science of man as we would in any other domain, that is by discarding entirely behaviourism and in fact, in my view, the entire empiricist tradition from which it evolved.

So you are not willing to link your theory about innate limitations, with Mr. There might be a certain connection. Well, if you had a changing system of limitations, this might be connected.


Well, the reason for what he describes, I think, is different. We have more possible sciences available intellectually. When we try out those intellectual constructions in a changing world of fact, we will not find cumulative growth.

What we will find are strange leaps: First of all I would like to ask Mr. Foucault why he is so interested in politics, because he told me that in fact he likes politics much more than philosophy.

But that is not a problem.Preface. Now that my Systematic Theology is again being reprinted, the Preface can be very brief.

It is not necessary to say much about the nature of the work, since it has been before the public for more than fifteen years and has been used extensively.

There is a place with four suns in the sky — red, white, blue, and yellow; two of them are so close together that they touch, and star-stuff flows between them. I know of a world with a million moons.

I know of a sun the size of the Earth — and made of diamond. There are atomic nuclei a few. Scientists have investigated this question for more than a century, and the answer is clear: the differences between people on intelligence .

We know that intelligence is a complex trait, so it is “influenced by many different genetic and environmental factors.” And we also know that we do get a certain amount of .

Is intelligence determined by genetics? Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. Intelligence is challenging to study, in part because it can be defined and measured in different ways.
