Its worse, it measures the specific "autistic" ability to discriminate arbitrary patterns(Ravens typically) which is not even present in all autists. In the process of evolution, how hard would be the selection pressure to distinguish abstract, monochromatic patterns? Thats why sub-saharan Africans score so low, they haven't been exposed to the concept of such patterns at all. IQ tests are so culture bound its not even funny. We think that "simple patterns" should be something universal but in fact the patterns been absent for most part of our history.
It would be better to replace such abstract patterns with more universal/realistic pictures(and make them more unique looking):e.g. photo of a tree, photo of a sun, photo of a pyramid/cat/fish,etc and compose tests from such photographs(replacing the small elements with photos). I bet IQ scores will skyrocket and people would pay more attention to tests.
The other problem with such tests is that they don't provide anything "fun" to solve. Any third-rate puzzle game has better graphics and gameplay. The general public view IQ tests as esoteric "logic/math abstract bullshit" and doesn't have any motivation beyond finishing the test as soon as possible. The same exact public would memorize the patterns and perfect any puzzle flash game they play a for a couple of hours. Even your mom could learn to play such a puzzle perfectly, despite not being an "IQ genius". Forcing oneself to take an IQ test is equivalent to playing a puzzle with no gameplay, no feedback, no graphics and no reward(beyond a score). Who would waste time training to solve IQ tests all day? Who would want to analyze abstract, primitive patterns all day? Obviously not anyone normal. That leaves only those types you could describe as autistic or pathologically dedicated to such tasks(an effort to "improve their IQ" by solving abstract, meaningless puzzles). What this leaves out is creative intelligence and lateral thinking/thinking out of the box, which is replaced by primitive linear, multiple-choice patterns which require only the ability of pattern recognition and basic analogical reasoning. You can't call that "Intelligence".
