Introduction to the Practice of Statistic
9. What advantage is there to having "blind" subjects in an experiment? O The subjects know what groups they are in, so they can behave the way the experimenter predicts. There is no subject bias because they do not know which group they belong to. There is no experimenter bias because they do not know which groups the subjects belong to. The experimenter will not know the role of each of the members of the experiment.
