I was just using it ("+3 sigma") to mean "high-level" creativity and could have just as easily said "99.9th percentile" or some other number. No, I don't know of a good way to test for it. My point is that there's a strong negative correlation, especially at the competitive upper reaches, between creativity and the sort os superficial reliability that (a) tends to determine a person's ability to advance in organizations, and (b) you'd probably want in someone you put in front of difficult clients on a regular basis.
