Quizplus · Accepted Answer

Keeping experimenters uninformed about group assignment is the best solution to the problem of experimenter expectancy effects as it eliminates the possibility of the experimenter's attitudes or behaviors affecting the results. Random assignment and different experimenters in different conditions are also helpful techniques, but keeping experimenters uninformed is the most effective approach. Allowing participants to choose their own condition may introduce selection bias and undermine the random assignment.
