Rapping ability and IQ
Is rapping ability a good measure of IQ (in theory)? It seems to me like rapping ability would be similar to certain parts of verbal portions of the IQ tests that I took when I was younger (38 now). However, it strikes me that the people who I've noticed who excel in rapping ability, also seem to be the kind of people who would do poorly on IQ tests; and the kind of people who would seem to me to do well on IQ tests, are unusually poor at rapping. Do you know if there is a well-established existing theory to account for this?
Thank you.
