I like reading Gladwell, he makes some interesting points at times, and he makes the NYC running community more interesting if that is possible.
Since Gladwell, and experienced runner who actually still pushes himself in the street mile, certainly knows the scarcity of HS sub 4 miles, it is an odd assertion. What is also odd is that the New Yorker, which prides itself on teams of meticulous fact-checkers, publishes stuff that a fairly observant sports fan, not even a runner, would question. The second assertion is nuts.
During the last winter Olympics Gladwell was pitching his book about underdogs (David and Goliath), and I attended an event, where Gladwell appeared with several Olympians who according to Gladwell fit his theory about underdogs being successful not despite their handicaps (too small, not as naturally gifted, etc) but because of it: they worked harder than everyone else to overcome their handicaps. I did not read the book, but this was certainly the theme of the panel. Mike Eruzione of the "Miracle on Ice" 1980 Gold Medal Hockey Team was on the panel that evening. We are both from the Boston area , so before the panel we had a couple beers and traded stories about growing up, MA pond hockey, why he never went pro after the Olympics, etc., he seemed like a genuinely terrific guy.
When the panel began Gladwell laid down his theory about why underdogs win, so compelling to underdogs like me, but so obviously untrue statistically. Eruzione listens quietly to Gladwell explaining how outmatched the US Team was by the Soviets due to their famous Red Army system, years of training together, international experience, and NHL skill level vs. a bunch of rag tag college kids thrown together at the last minute. Eruzione starts with "that could not be more untrue"..."we we won because we were a great team." He carefully unpacked each one of Gladwell's arguments; the team had actually been carefully chosen by a top coach, most were from U. Minn or Boston U. and trained together for 6 months, played like 60 international exhibition games prior Lake Placid, with the specific goal of ending the string of embarrassing losses to the Soviets. Gladwell did not seem to care or know that Mike was doing a live fact-check, the geek vs. jock, I was sort of embarrassed for Gladwell and the other Olympians on the panel who had sucked up to his theory about being these loser underdogs who made it to the Olympics. Eruzione was convincing, I did not bother fact checking him, but I give him the gold.
