Quizplus · Accepted Answer

By using a placebo-control group, Dr. Pine is reducing the impact of experimenter bias. This means that since he does not know which patients received the real drug and which received the placebo, there is less chance that his expectations or preconceptions about the drug will influence the results. This is important for ensuring the validity of the study.
