Subjects played 12 rounds of the fantasy baseball prediction
game. In this game, all subjects were shown extensive statistics
about two teams and asked to make a prediction about
the score of the game between the two teams. To ensure that
only the available statistical information was used to inform
decisions, the names of the teams were not revealed to subjects.
Additionally, the games subjects were predicting were
games that had already been played. Subjects were told that
even though the games were past games, all statistics and algorithms
in the study treated the games as if they were in the
future.
