Question

Quizplus · Accepted Answer

Double-blind studies control for the effects of both participants' and experimenters' expectations. In a double-blind study, neither the participants nor the experimenters know which group is receiving the treatment or placebo, which helps to prevent bias and the placebo effect. Double-blind studies do not control for carryover effects, regression to the mean, or participants' and experimenters' ability to see each other.
