There is abduction in games. Players deliberating aboutpossible future histories take those positions, which according to the standardcommon knowledge and belief of rationality will never actually be reached, asthe surprising facts that need accommodation. The need for such accommodationsets their minds in motion and trigger reasoning from effect to causes. Playersare prompted to reason to an antedating action under which such positions wouldbe rendered comprehensible, less surprising, or facile and natural. In games,reasoning abductively means to imaginatively look for where perturbations, suchas trembles or quantal responses, could take place. Its conclusion is aconjecture about such perturbations.
