Concept of IQ is outdated

Yes. In Frames of Mind , Gardner argued that the concept of IQ was completely outdated and that it represented largely (Western) cultural values for language and math skill. He made the point that different cultures may well value different skills, and thus consider someone "intelligent" in their cultural setting who might not be considered so in another setting. Somehow, his notion of the cultural influence on our definition of intelligence became misappropriated into the identification of intelligence by ethnicity. I can only imagine how outraged he must have been!
