Cultural Jews. I think it happened because different teams of Extra-Terrestrial creators created different groups of people. I have talked about this through many subjects on this forum. You might try what was the very popular Aliens and the Bible thread.
I talked with Gardner face to face and asked him why he didn't include creativity in his intelligences. I was not satisfied with his answer. Yes and so I have also mentioned that there is general IQ and governing IQ. There are many different areas of IQ. The SAT still has many different topics even if it is focused on reading, writing and arithmetic, and it has the least number of areas (unless you mean like the Math SAT).
Hmm...its been a while for me since I've studied this, but from memory Gardner was more focused on 'types' of intelligence. Almost like subject areas. So he would see creativity as being an inherent property of being intelligent in linguistics (for example) but not that it would necessarily carry over to other areas (musicality).
DeBono was more focused on modes of thought, and creativity was certainly one of those. Perhaps combining the two gives a useful matrix?
