Once there was a highly intelligent turkey that had nothing to do but reflect on the world’s regularities. Morning always started out with the sky turning light, followed by the master’s footsteps, which were always followed by the appearance of food. Other things varied, but food always followed footsteps. The sequence of events was so predictable that it eventually became the basis of the turkey’s theory that footsteps bring food. One morning, after more than 100 confirmations of this theory, the turkey listened for the master’s footsteps, heard them, and had its head chopped off. Scientific theories can be revised upon the discovery of inconsistent evidence. Suggest how the turkey’s theory might be modified so the remaining members of the flock would find it more useful for making predictions.
