I agreed with tocomment that it was a biased sampling not in the sense that planetary systems happen to be this way in the region we are looking at, but in the sense that planetary systems seem to be this way when we look at things from THIS set of instrumentation and methodology.

IOW, I disagree with NPR's claim that "Our Very Normal Solar System Isn't Normal Anymore". Addendum: It may indeed be abnormal. But we don't have data to conclude that yet, or even to suspect it.
