Document 8: Alain Ledoux: Alain Ledoux is the inventor of the guess 2/3 of the average-game. In 1981, Ledoux used this game as a tie breaker in his French magazine . He asked about 4,000 readers, who reached the same amount of points in previous puzzles, to state an integer between 1 and 1,000,000,000. The winner was the one who guessed closest to 2/3 of the average guess. In 1995, Rosemarie Nagel revealed the potential of guessing games of that kind: They are able to disclose participants´ "depth of reasoning". Due to the analogy to Keynes´ comparison of newspaper beauty contests and stock market investments the guessing game is also known as the Keynesian beauty contest. Rosemarie Nagel´s experimental beauty contest is a famous game in Experimental economics. The founding father of this game was unearthed in 2009 during an online beauty contest experiment with chess players provided by the University of Kassel (Germany): Alain Ledoux, together with over 6,000 other chess players, participated in that experiment which looked familiar to him.
Document 9: Shannon switching game: The Shannon switching game is an abstract strategy game for two players, invented by American mathematician and electrical engineer Claude Shannon, the "father of information theory" some time before 1951.

The other player aims to prevent this by using their color instead (or, equivalently, by erasing edges). The game is commonly played on a rectangular grid; this special case of the game was independently invented by American mathematician David Gale in the late 1950s and is known as Gale or Bridg-It.

The top value of a painting in the 1970 edition is $1 million, and $10 million in the 1996 edition; however, getting the full value for the painting requires some luck in landing on the right square on the board to sell a painting to the bank.
