Question

Quizplus · Accepted Answer

Double-blind control is the most effective way to control for the allegiance effect. This involves neither the experimenter nor the participant knowing who is receiving the intervention or placebo. It eliminates the possibility of experimenter bias by ensuring that neither the experimenters nor the participants know which treatment is being administered, making it an effective way to control for the allegiance effect. Correlation studies and epidemiological studies do not control for experimenter bias, and placebo pills are used to control for the placebo effect, not the allegiance effect.
