Your first point is what I was trying to get at - basically the culture is the 'test data' and IQ would be the capability of the 'hardware' or genetic make up of an individual brain/person in this case. I think your point about intelligence not existing in an individual is too narrow, but ultimately that comes down to how you decide to define intelligence. Not sure I agree that AGI won't happen - in fact I suspect the computing power we have now is good enough to do it, but we're just missing some insight with how.
