I haven't read Gladwell's book, but does it compare Korean and USA PDI and disaster rates, or disaster rates from a large number of countries?
If Gladwell has looked at a few more countries (and perhaps even ploted PDI against crashes) then he's done a much better job than Greenspun's comparison of "Foriegn" and "US" pilots.
If not, then the ball would be in Gladwell's court (so to speak).
It's obvious that Greenspun knows US air safety better than Gladwell though.
