Using a double-blind experiment can control both research participant bias and research bias. This is because neither the participants nor the experimenters know which group is the control or experimental group, which minimizes the potential for biased results. Randomly selecting participants or assigning them to groups can help control participant bias but may not fully address potential research bias. Using a single-blind experiment can also help control participant bias but does not address potential biases from the experimenters.
