Hey want to provide some quick clarification on your point. First, you are dramatically, 110% right that pop psychology books plunder really valuable research such as this for ultimately banal insights that they manage to hide in a 300 page book that could be 10 pages. K. Anders Ericsson, the absolute giant in the field of expertise research, is quite dismissive of Malcolm Gladwell and upset at his mis-interpretations of his work. Go look at his book, "Peak", which goes into depth on this (and funny enough looks like every other stupid pop psychology book, although it is not). Finally, if you want to explore the best research we have from the present through the last 40 years, highly recommend you check out "The Cambridge Handbook of Expertise". It's 40 chapters written by nothing but PhDs. They compare what expertise means across History, Firefighting, Surgery, Ballet, even Truck Driving and Software Design.
