OP asked for a specific point. You wrote: "his remarks about easy versus difficult problem solving relied on a preliminary study that failed replication when applied to a larger experimental group, a fact he omitted from his book". Could a layperson work out which specific point you're referring to and then understand it? Perhaps you'd care to elaborate.

Indeed he did -- he said, "I was not able to identify a specific point that Gladwell has made that is false." In my reply, I gave an example where Gladwell published something that had not been replicated, always a risky practice in science journalism, but worse, it was an example in which an ambitious effort at replication has failed.
In short, Gladwell published something that had been proven false, a case in which a cautious reading of the literature would have prevented this error.
Also, the original study came from the field of psychology, a field that's famous for superficial studies that lead to grand but unsupportable claims. Even for psychology studies that have stood unchallenged for years, one must be very careful in taking their conclusions seriously.
The Gladwell example I used represented something that was false, that had been falsified, something that all scientific results, to meet the definition of "scientific", must have as a possible outcome (testable and potentially falsifiable).
