Check out this, it is a truly fascinating study and is still ongoing:

It is not the first but it is the longest, started as a long-running cohort study of 1037 people born between 1 April 1972 and 31 March 1973 in Dunedin, New Zealand. Great emphasis is placed on retention of study members. At the most recent (age 38) assessments, 96% of all living eligible study members, or 961 people, participated. This is unprecedented for a longitudinal study, with many others worldwide experiencing 20–40% drop-out rates.
Interesting indeed. But I was famous in my time at the university for finding "problems" in the publications of others. In other words, I am and I always was the negative "advocatus diaboli" or "the heretic" alias "der Ketzer".
I found immediately a link to a publication derived from this study with results I partly doubt right from the first abstract:
Polygenic Score for Higher Educational Attainment is Associated with Larger Brains
Abstract. People who score higher on intelligence tests tend to have larger brains. Twin studies suggest the same genetic factors influence both brain size and
academic.oup.com
Quotation from there: "People who score higher on intelligence tests tend to have larger brains. Twin studies suggest the same genetic factors influence both brain size and intelligence. This has led to the hypothesis that genetics influence intelligence partly by contributing to the development of larger brains."
For most scientists and brain researchers in Europe, these few sentences could already lead to "hellish dangerous conclusions" without immediate further explanations because in a larger brain, there certainly could be more connections and links between so-called "synapses" etc., etc.
So far, so good, but you cannot draw a conclusion by saying that larger brains automatically are a reason for higher scores in intelligence tests.
You also need to explain immediately the relations of these larger brains! You might ask: In relation to what?
For example to the average body size of human beings because men's bodies are usually bigger than women's ones and the brain is always a part of the body in relation to the body size. By saying, a larger brain tends to more intelligence, you could easily exclude women from the assumption of the same intelligence as men or of higher intelligence at all.
Because this really has been done by so-called "scientists" for a long time - and we all know some parts of the world, where this is still done - we should be very careful with such sentences and conclusions.
Therefore and especially in brain research, there has always to be used the expression of "in relation to the body size" or something similar, because there are also a lot of animals with bigger or larger brains than human beings but they are not really more intelligent than we are - although their brains are really obviously bigger than ours, they are usually smaller in relation to their body size than ours (e.g. horses, hippos, elephants!) - with only one exception as far as I know:
Dolphins are even having in relation to their body size a brain which is bigger and larger than the brain of human beings and they probably use the additional brain parts for hunting by sending and receiving ultrasonic waves.
Moreover, in my own feelings which sometimes tend to a kind of "mysticism" which I certainly doubt in myself because I am also a heretic for my own beliefs,
I tend to believe that there are "spheres of intelligence" which are outside of our bodies and possibly a kind of "natural instincts" we human beings might have lost in exchange for our analytical "human" capabilities.
For example and on the one hand, I doubt very much that we ever could talk with a dolphin about arithmetics or quantum physics.
On the other hand, I once read that tiny termites are building in their "skyscrapers" perfect "domes" for the room of their queen. Their workers start at the same time at different ground levels and they are meeting at the same time for perfectioning the cupola of their dome. They are too small to have something you could really call "a brain" and unable to see the opposite side of the dome, not to speak about the perfect curves they are building far beyond their bodies in the height of this dome. So, where do they get their architectural abilities from? When this is "swarm intelligence", how is the information about building a perfect cupola transferred to all the other termite workers?
There is so much about intelligence which we still do not know and we believe we are "the most intelligent" beings on this planet! Are we really?
