ADMS 2511 Lecture 19 Notes – Can intuition really help you win a chess game?
Introduction
• Affectively charged, meaning that it engages the emotions.
• While intuition is not rational, it’s not necessarily wrong.
• Nor does it always contradict rational analysis
• Rather, the two can complement each other.
• Intuition can be a powerful force in decision making.
• Nor is it superstition, or the product of some magical or paranormal sixth sense.
• Intuition is complex and based on years of experience and learning.
• OB in the Street shows how intuition applies to grand master chess players.
• Apparently so.
• Novice chess players and grand masters were shown an actual, but unfamiliar, chess
game with about 25 pieces on the board.
• After 5 or 10 seconds, the pieces were removed, and each subject was asked to
reconstruct the pieces by position.
• On average, the grand master could put 23 or 24 pieces in their correct squares, while
the novice was able to replace only 6. Then the exercise was changed.
• This time, the pieces were placed randomly on the board.
• Again, the novice got only about 6 correct, but so did the grand master!
• The second exercise demonstrated that the grand master did not have a better memory
than the novice.
• What the grand master did have was the ability, based on the experience of having
played thousands of chess games, to recognize patterns and clusters of pieces that
occur on chessboards in the course of games.
• Studies also show that chess professionals can play 50 or more games simultaneously,
making decisions in seconds, and exhibit only a moderately lower level of skill than
when playing one game under tournament conditions, where decisions take half an
hour or longer.
