"I fail to see how asking to choose a specific geometric figure out of four can be culturally biased"
I think a lot of newcomers from very poor countries may not be exposed to some things as often, they might not be thinking about shapes and geometry in the same way - more importantly, the notion of tests and test taking.
Solving little abstract problems in a test format as we understand them ... I think is something that's only normalized in certain countries.
I think there's enough potential variance in those things to make a difference.
It's not like people can't grasp what a 3D cube is ... but some cultures just may have that much more exposure to things, more familiarity. Enough to move the needle.
I went to a French immersion school as a kid, in an English city. I studied mostly in French for most of the day until high school. When they did some kinds of testing, there were 'word tests' which depended on some degree of vocabulary.
Though my peers were basically 'a cut above' in almost everything (French immersion was basically public school's version of private school) ... we did noticeably more poorly on that test, granted the lexical nature of it makes 'cultural bias' more obvious.
I think it's 'a thing' though maybe a small thing.
Word tests are used as part of good, high quality IQ tests (e.g. WAIS and Stanford-Binet, though obviously not Raven’s). They are in fact one of the most useful and predictive parts (I.e. they are most g-loaded). They are biased (i.e. not measurement invariant) if you compare subjects from different countries/cultures, but they are not biased if you compare subjects from the same country/culture. For example, the score on word analogies sections has exact same predictive validity for white Americans as it does for black Americans. See Arthur Jensen’s “Bias in mental testing” for a very comprehensive treatise on the issue.
