Using a double-blind design is the most effective way to eliminate experimenter bias as both the researchers and participants do not know which group is receiving the treatment or placebo. This ensures that neither the researchers nor participants can unconsciously influence the results. Incorporating random variables and using placebos are important steps in controlling for other variables, but they do not directly address experimenter bias. Hiring ethical research assistants is also important, but does not account for the possibility of bias from the main experimenter.
