One player first sends a message indicating an intended play, which is either favorable or unfavorable to the other player in the game. After the message, the sender and the receiver play a simultaneous 2×2 game, in which the sender may or may not...

The Peter Principle: An Experiment The Peter Principle states that, after a promotion, the observed output of promoted employees tends to fall. Lazear (2004) models this principle as resulting from a regression to the mean of the transitory component of ability. Our experiment reproduces this model in the laboratory by means of various treatments in which we alter the variance of the transitory...

As a whole the group did worse than would be expected by guessing at random on each tasting trial. Some psychological biases, one possibly as a result of the design, are indicated by the results and a possible remedy suggested. The dan...
