I'm curious what Richard Haier's view is on the late Anders Ericsson's book(Peak: secrets on the new science of expertise) and his other works on expertise and how its developed.  Especially the claim that deliberate practice is essential in the developement of all talent.  🤔,(reply>), @Peter Lund I see. Are there any good examples of cases or studies where people with high IQs used significantly less than the average practice (deliberate practice)  time required  for expertise in a given field?,(reply>), Ericsson talks down the role of intelligence to an outright fraudulent degree in the papers/books I’ve read. Of course practice matters. Of course <b>deliberate</b> practice matters. Still, intelligent people usually need less practice — often a LOT less.
