Sort of; even the non-verbal portions have different means across cultures, AND the neuropsychological abilities that predicted higher scores differed across cultures as well. https://pubmed.ncbi.nlm.nih.gov/24055883/ https://pubmed.ncbi.nlm.nih.gov/24055883/ So what exactly an IQ test is measuring differs between cultures (though it certainly is measuring -something- since there are other correlations), since even the separately identifiable and measurable abilities that lead to someone doing well on an IQ test differ across cultures.
