  1. Yes, intelligence is genetically determined. No, this does not mean that it is impossible to become smarter.

    Let's start from afar…

    It is important to understand what it means to “determine” in the understanding of genetics.

    We have a genotype and a phenotype. Genotype defines the phenotype. However, two or more organisms with the same genotype (clones, identical twins)can differ and actually differ from each other, and this is more pronounced the more extensive the genotype. Genotype is just a threshold condition of the phenotype that determines the spectrum of possible polymorphism. Specific forms are determined by the dilution conditions of the environment (in this case, everything except the genotype belongs to the environment).

    Imagine that you are shooting a machine gun at targets: take the same machine gun, apply the same effort, point the weapon at the same point, take the same targets — all the same, the pattern formed by bullet holes will always be different.

    … because a phenotype is a genotype thrown out to meet environmental conditions.
    The structure meets chaos and generates variations.

    Yes, there are many traits that strictly correspond to the genotype. But there are exceptions… there are known cases of people being born with a female phenotype and a normal male genotype: just the Y-chromosome caught on X and did not cause the release of androgens during the critical period. And on, on, on…

    At the same time, most of the traits still correspond to the genotype only partially. For the most part, what we are is the result of a combination of genetics and environmental conditions. There are even signs that are only genetic predispositions, and�

    Yes, genetics largely determines our lower and upper limits of intellectual abilities, limiting our ignorance from below and intelligence from above. This means that intelligence is genetically determined. But it depends on the environment, and in many ways on our efforts, exactly where our mental abilities will be on this scale.

    We all have hope for intelligence — and for stupidity.

  2. If the design of the car is such that it can not accelerate more than 200 km / h, does this mean that it is impossible to go slower? No, it doesn't. And when you go slowly, you have the opportunity to go faster, to get smarter. No one (except seriously ill people) is born at their “maximum speed”, it still takes a long time to step on the gas. Yes, some of them accelerate faster. But I don't think that any of the healthy people in the world have reached their natural limit, and therefore there is a lot to go.

  3. Apparently, this is true. At least, this is the conclusion that IQ studies come to – the intelligence indicator remains unchanged, no matter how hard they try to train it. The maximum that can be achieved is to learn to pass well certain tests that show the level of IQ. But if you change the principle of testing, the indicators remain unchanged, because the level of intelligence does not change.

  4. Intelligence is not even exactly defined yet, what can we say about what's going on with genetics 🙂

    Intelligence is a combination of cognitive abilities and skills. It can be developed, or it can be degraded.�

    I love the CPU analogy. Look at this. In divinity, the store sold, for example, a four-core pentium, but its turnover is weak. And it will be less productive, all other things being equal, than a dude with two, but sooooo fast cores.

    However, this is only the CPU. How much oprative memory was sold to you?

    If at the divine sale you were lucky and you still got yourself a fast powerful percentage, and a bunch of operatives, and you have a modern chipset and video memory car, in general, if you have your computer turned out to be full of stuffing, then the next question is: what programs did you put on it and what do you do on it?

    So not everything is predefined 🙂 Your intelligence is collected from different cubes and you can fill these cubes with the right content.

  5. If intelligence really was genetically determined, then yes… it would be impossible to become smarter than it is defined in the genes. Fortunately, this is not the case. Intelligence develops over the course of a lifetime. (If there are no organic violations.) Its training takes place by solving practical problems. Especially active in early childhood. Well, then it all depends on the circumstances.

    The main problem is that in the modern world, the task of survival does not require much intelligence. When a person lives in a large city in the care of their parents, they almost do not face complex problems. In such conditions, there is only one way to improve your intelligence. You need to set yourself tasks artificially and try to solve them. In early childhood, special educational toys are used for this purpose, which not only entertain, but also puzzle. Then it's time to go to school, where children are given more complex tasks. For those who can do school tasks easily (i.e., those who can do them easily). those who had better educational toys) need to study somewhere else, where they set even more complex tasks. Etc. Development takes place through overcoming oneself. “No pain, no gain.” Without suffering, there is no progress. This fully applies to intelligence as well. The intellectual muscle is designed differently, but the way it is pumped is the same: the maximum load is within the current capabilities… and diversify as much as possible. Alas, in reality, very few people do this. Most people, instead of solving even the tasks that need to be solved, try to somehow get and use ready-made solutions. Without realizing that they are signing a sentence for themselves. For success in life, nothing is more important than intelligence.

  6. Man is triune in the likeness of the Creator and has a spirit, a soul, in which the person's personality and body are concentrated.

    All these three levels operate according to the same principles and laws, and the mind, as well as the will or emotional balance, can be trained in the same way as the muscles.

    That is, we have a source code of some level and the ability to train it to some extent.

  7. The concept of intelligence, as it seems to me, is not deterministic in itself. The brain can be represented as a neural network that is able to solve certain tasks. And it is clear that for different people it is sharpened better for some tasks and worse for others. But this network is flexible and can be rebuilt. 1) We could measure intelligence as the ability to solve problems, in a sense, give out Y while receiving X as input. Then, first of all, you need to decide on specific tasks for which to measure this value. Because a fixed-size neural network cannot adapt to all possible X -> Y mappings. So we will choose a certain set of tasks for evaluation, for example, logic and generalization ability. I am not an expert in biology or genetics, but I would venture to assume that the number of neurons in healthy people is not very different. Then any such person, after spending a certain amount of time, could train their network on these very tasks-logic and thus increase their intelligence. But this definition is not without flaws, because if plasticity is different for each individual, then someone could train themselves much faster than others. � 2) We can measure intelligence by the degree of brain plasticity. I don't know exactly how everything works, but most likely it is different for all people and changes over time – for children it is large and decreases with growing up. But this definition probably won't suit us very well either, because we have a strong liking for a certain range of skills, such as the ability to solve logical problems, because this is necessary for our survival. Many people tend to think that adults are more intelligent than children, because the latter have not yet managed to master these most common skills well. It turns out that intelligence is some kind of combination of plasticity and current fitness. The latter depends more on you.�

    In general, this class of skills could be chosen by others. Perhaps in a parallel universe they value illogicality or even random signals in synapses.

  8. Even if you have an old computer, you can optimize the processes of its software and it will work faster. With the brain as well. In addition, don't forget that there are different methods for solving different tasks. Even with a low speed of problem solving, but with extensive knowledge and ability to use them you'll actually be smarter than those who think faster.
