There isn't as much an emphisis on inventing stuff as there is contributing to already established work. Obviously only a subset of a given population will have 130+ IQ points necessary to invent new things. Also there isn't much to invent anymore, the western civilisation is pretty much at its peakThere is a difference between IQ and Creativity. IQ is just spotting different shapes, adding things back together that are missing, spotting patterns. Give them a real world problem and real world solution, you will find 99% of people struggling. That's why CEO-Presidents-Military Leaders-ETC are probably not 'high iq' but 'creative' they can turn a real life problem and convert it to a real life solution!!! you simply can't do that through putting shapes and figures together in IQ tests. That's why you see 99% of the people that come out of universities, not a single one actually 'invents' anything!!!
