<human>:  I have a question about the Stanford prison experiment. Who was the prisoner who was released after the experiment?
<bot>: That would be the prisoner who was released after the experiment. The experiment was conducted by Philip Zimbardo in 1971. The experiment was designed to study the effects of power and authority on human behavior. The experiment was conducted in a mock prison, and the participants were randomly assigned to be either guards or prisoners. The guards were given the power to punish the prisoners, and the prisoners were given the power to punish the guards.
