A researcher strongly believes that physicians tend to show female nurses less attention and respect than they show male nurses. She sets up an experimental study involving observations of health clinics in different conditions. In explaining the study to the physicians and nurses who will participate, what steps should the researcher take to eliminate experimental bias based on both experimenter expectations and participant expectations?
