I don't know whether anybody's said this already but it occurs to me that the question isn't so much about how intelligent we are, more about how we are intelligent.Can't remember whether that's Goleman- or Gardner-speak, but for me its about some of us finding it relatively easy to understand how a flower grows but immensely difficult for us to understand and use a musical instrument. For others music might be easy but playing football is difficult. So what are we going to measure?
