Personal Notes On Expertise [Unofficial]

  • Vast organized knowledge
  • Representation of knowledge/problems/situations
    • Low level details are chunked into (networked) systems of bigger pieces
  • High level plans
  • High level pattern recognition
  • Experts are better meta-thinkers. They continuously learn from feedback, learn how to learn, learn how to improve performance, learn how to deal with emotional intelligence issues.
  • “The key is deliberative practice: not just doing it again and again, but challenging yourself with a task that is just beyond your current ability, trying it, analyzing your performance while and after doing it, and correcting any mistakes. Then repeat. And repeat again.” – Peter Norvig [1]
  • “They [Chess Grand Masters] talked about configurations of pieces like “pawn structures” and immediately noticed things that were out of sorts, like exposed rooks. They weren’t seeing the board as thirty-two pieces. They were seeing it as chunks of pieces, and systems of tension. Grand masters literally see a different board.” [2]
  • “The experienced SWAT officer doesn’t just see a man walking up the front steps of the school; he sees a nervous twitch in the man’s arm that calls up associations with dozens of other nervous twitches he’s seen in his years of policing. He sees the suspect in the context of every other suspicious person he’s ever come across. He perceives the current encounter in light of past encounters like it.” [2]
  • “We don’t remember isolated facts; we remember things in context.” [2]
