^^ Wise and well thought-after post, Katsuni.
I agree the most with this line in your writing:
These tests *DO*require intuition to figure out, why some system or "logic" behind some question is better than another. I'm seeing that many people are disappointed with it. It's extremely, utterly clear to me that it is their opinion.As such, the best yeu can do is try to guess whot the most likely situation is, or whot the creator "wants" yeu to think, in which case it becomes less a test of formal logic, and more informal intuition.
I believe it is clear for many others, as well: many different theories, systems, abstractions - or by whatever name you want to call them - would produce any and all the answers provided for in the IQ tests.
Infinite explanations, finite responses.
Hold a pause and think for a while. I've had.
IQ tests require some logic to verify that a given "system", like an arithmetic progression of numbers, rounded down, will produce some answer X that is being sought.
Intuition is needed to sort out what kind of system of logic would be useful for most situation, given the context of IQ test and extrapolated in the real world. There are several factors which influence the kind of system wanted, and it's a part of intelligence as well.
A good logic by which to answer a question has following qualities:
No more complex system should be needed for an answer than seems required. This requires understanding of what differentiates complex and simple. If a complex and simple explanation have an equal power to explain or predict, simple one is preferred for most stuff humans do.
A simple explanation is accessible to more people than a complex one, making it superior, provided that the test taker has the intelligence of wanting to be able to communicate with a larger population.
All of this is intelligence.
A good logic explains flawlessly what it is set out to explain. If we assume a logic of a series of natural numbers, ordered, for one question - it must match the information already in the question, namely, the numbers present.
If we assume a logic that the question, "find items of a same kind or class" describes four-legged mammals, we must see that all the items we would include in an answer are indeed four-legged mammals, and no four-legged mammals are left out, lest we should change our assumption of the background logic.
IQ tests attempt to measure intelligence in relation to aspects of the real world, which is why the logic of choice for a particular question should be usable. The logic should have an application to life.
IQ and IQ distributions in a population are planned, crafted, engineered and designed to indicate those who have the mental capacity to do well in the population in a specific, mental way. This does not include good work habits, being a hard worker or knowing the specifics of some obscure profession. It does include the ability to collect information, verify it, explain it, and the ability to investigate and inspect one's own ideas.
Concept of IQ was born out of the idea to pick apart those who needed more than a standard amount of education to pass through school tests, which prepare one for life. It's expanded to find out those individuals who can do well, too, in the context of academia, schoolwork and society. IQ is an attempt to find out people who can do well. In part, it does find, so it works somewhat. It doesn't work absolutely (what could), but success is an aspect of IQ.
Hence, usable logic, "logic worth of something" is saught in IQ tests. Not logic that wouldn't get one very far.
This is situational, and the world is huge, so this one needs the insight from a person who's much alienated from the world, or from someone who can't see how the people have set out the "correct" answers in any real life task in any of the various fields: they're set out to be rather regular, when possible. Consistent.
IQ tests can't address the fact that a huge flow of irrelevant information comes our way. IQ tests mostly measure only the more "regular" part of our information processing in the world.
IQ test is tied with the world, as there's a specific role designed for IQ testing. It's designed to find those who have specific mental capacity to do well in the world. It doesn't address qualities outside it's scope. The scope is fuzzy, and we can't know exactly what it is.
IQ test caters to regular parts of the information systems formed by real people in the world. We form regular systems of information to handle many tasks that come ahead. As an attempt to control the flow of information, people prefer rather regular and simple systems, as simple as possible. People in general prefer systems that are understandible, too. IQ tests measure the ability to understand this, too.
And yes, faster is better than slow, and it's not efficient use of one's time to spend too much on an answer. If the test's setup is to finish in time, an intelligent person will adjust and answer the questions in time in order to finish with a high score. A timed system suits better for the purposes of competition, as finishing tasks slowly is trivial compared to doing them fast. This is why the ability to produce more correct answers per time is more valuable than the ability to produce them at a slower pace.
