So for the next couple of years I made a habit, when giving talks, of posing the question to my audience: Which is more valuable, good ideas or good people? No matter whether I was talking to retired business executives or students, to high school principals or artists, when I asked for a show of hands, the audiences would be split 50-50. (Statisticians will tell you that when you get a perfect split like this, it doesn’t mean that half know the right answer—it means that they are all guessing, picking at random, as if flipping a coin.)
