yes, we need more.
thanks for bringing notice to this important matter.
what is IQ what does it have to do with intelligence?
You can look at what the tests measure, and how those skills are used in reality.
Usually, IQ scores measure both answers to questions about mental skills, and verbal skills.
The mental skills are about seeing visual patterns or symbols, and inferring the correct next item in the sequence, or determining which of the items is out of place, which is another use of being able to infer the missing item in the sequence, which is another version of identifying the next item, when the set is unordered.
That is incredibly useful for identifying patterns in repeated experiments and evidence. It's not so great for real life, because you don't normally get 10,000 experiments. But it's great for industry, as then you have someone that can spot that special pattern that gives the indicator of what factors are the most important in the phenomena being used, and thus what is the best way to solve the problem, on an industrial level.
The visual skills are mostly about identifying vocab correctly, which is necessary for communicating precise technical details in precise STEM fields, where a slight misunderstanding can ruin the whole technology that you're trying to build.
Put together, someone with high levels of both skills, can provide the creative insight, something that is vital to the development of STEM products by wealthy corporations, to make them wealthy, to make WMDs to protect their country, and to develop STEM tech that can advance humanity and even make humans live longer, but that is rare enough that it simply cannot be bought by just having lots of money. Those people have to be sought out, found, and then supported and encouraged to help the world by helping to develop industry.
IQ tests are statistical models that look at the mental grasp a person has. It looks for the dexterity of the mind. How many segments it can put together. It says nothing about what has been put together or what will be put together.
The objective is to obtain the person with the skills to handle almost any such situation, because in real life, their employers will want them to perform several dozen tasks over their lifetime, each with different things that have been put together, and different things that you want to be put together.
It only looks at the sharpness. metal dexterity. But the model is limited in that people with high mental dexterity are hard to find.
If they were easy to find, the corporations and governments could find people with high mental dexterity very easily, even without the aid of IQ testing.
And it measures perception poorly.
The idea is to be mentally dextrous enough that the person with high IQ can look at things from dozens of hypothetical perceptions, till he comes across a perception that accurately represents reality.
IQ for example, has a way higher correlation for mental illness than it has for long-term life success.
Most Western schools teach hours of maths and science every day, which is dead easy for high-IQ people and consequently very boring to them.
The vast majority of people will hardly ever need to use maths or science beyond basic arithmetic and basic CPR in their jobs or the rest of the things they do in life, both of which they'd get taught.
So high-IQ people spend most of their time being bored, while other people get to be shown how to be more like high-IQ people, when they'll never need to be like high-IQ people, which makes their intelligence seem less impressive and less valuable, and so not deserving of any special help.
But schools don't offer classes on communicating to people who are of a very different approach to you, which is what you get when two people have different IQs. So that makes it incredibly hard for high-IQ people to communicate effectively with average people. That in turn makes it incredibly hard for high-IQ people to know how to communicate their wants and needs to most people, in a way that will result in most people understanding their wants and needs and ensuring that their needs and wants are met.
Basic practical skills are treated in a somewhat similar manner. There was no "woodworking for dummies" classes in school. There was only "woodworking classes for those who already know what they're doing making things" classes, which doesn't really bode well for those who have more natural ability for abstract thinking, than practical tasks like fixing a leaky tap.
At the same time, they are also encouraged by the media to think that social skills are something people develop naturally, which gives high-IQ people the impression that their high IQ is some kind of mental handicap that is the price one pays for having a high QI.
So the result is that they think that there's no point in developing basic social and practical skills, because they think they can't, and so they don't try to develop them, and so they don't develop those skills.
So if their parents didn't raise them in a very supportive & encouraging environment, then many of them can still be stuck in a mode where they think that social skills & practical skills are beyond their mental capacity to learn.
