Is there cultural bias in the measurement? Perhaps, though if there is I don't really care because that doesn't interfere with the fact that there is no cultural bias. [/quote]
Measurement bias is a huge issue. No test or assessment is valid of their is bias in the measurement.
And again, there is a HUGE scientific literature showing tons of measurement bias in IQ tests and other standardized test.
And much of this evidence does show that there is cultural bias, gender bias etc. by showing that demographic groups score just as high as say white males if they're given different versions of the tests that ask about the same concepts but with different question wordings etc.
For instance, you note that abstract thought etc. shouldn't vary culturally. And you're right. But various other things like vocabulary, understanding of concepts used in the questions etc. used to measure abstract thinking can definitely vary culturally. And that biases the tests.
Someone may answer a question wrong simply because they didn't understand a word or example used to ask the question, when they can get it right with a different question using wording they understand. Thus the questions aren't only measuring the concept they are designed to measures, but also the persons vocabulary and other factors unrelated to the abstract thinking ability it's supposed to be measuring.
Sure, simple questions like the choosing the next item in a series example you keep citing aren't so applicable to wording issues. But that's just one item. Other items are more complex and involve more explanation in the question etc. that can throw people off.
But anyway, you're ranting on this topic is why this subforum gets so

ing frustrating to try to participate. There's HUGE volume of scientific research showing cultural bias in IQ and other standardized tests, but just keep spouting off you're uniformed opinions over and over again like it's fact. If you want to have a leg to stand on, go read some of the research on the topic and see if you find studies that support your assertion of no cultural bias in IQ/standardized tests. Otherwise shut the

up.
And this kind of crap is why this whole country pretty much sucks donkey balls. It's full of opinionated dimwits who only care about their own opinions and beliefs and put no effort into becoming educated and informed and using scientific evidence where possible to form their beliefs, opinions and stances they take.
Being intelligent and educated and relying on science is becoming the 21st century's version of witchcraft, and the country is being ran by whichever group of uninformed morons can shout their rhetoric the loudest and shout their opinions often enough that they start to be taken as fact.
There's that old quote of "Everyone is not entitled to their own opinion. They're entitled to their own
informed opinion." or something along those lines. People really need to heed that and knock off the trend of being super opinionated about things they know little about.
