A double-blind experiment is an experimental method used to ensure impartiality. When both the researcher and the patient are ignorant to the actual ingredients, therefore the trial is completely unbiased. I believe this method is a better way to carry out a trial because the researcher can subconsciously influence the experimental outcome. ACcidentdently, letting the patient know about what substance they are receiving can skew the results of the experiment. Even though scientists are honest people, some might favor a patient receiving the drug vs the placebo, this can also skew the results. Or if a scientist is part of a huge company or fighting for a grant they might generate positive results to fall ahead; this can all be avoided by a proper double-blind study. Manipulations of results are fatal for a drug trial and the health of future users and a double-blind study does a better job of keeping all aspects unbiased.
