Quizplus · Accepted Answer

Conducting a double-blind study is the best strategy to reduce experimenter effects. This means that both the participants and the experimenters are unaware of which group received which treatment. This helps to eliminate bias in the study and increase the validity of the results. Using a between-subject design can also be helpful in reducing experimenter effects, but it doesn't completely eliminate the possibility of bias. Using confederates or a cover story may also help reduce experimenter effects, but they are not as effective as a double-blind study.
