Keeping the experimenters blind to the purpose of the study is a strategy used to reduce the impacts of investigator and experimenter expectancies. This helps ensure that experimenters do not form biases or expectations that could influence the results of the study. Reiterating basic experimental procedures, carefully describing and making explicit the experimental procedures, and analyzing the data for differences across experimenters can all be helpful in reducing the potential for bias and improving the overall validity of the study, but they are not specifically targeted at reducing investigator and experimenter expectancies.
