Placebos are used to ensure that the study remains free from bias because neither the participants nor the researchers would know who is receiving the actual medication. The placebo must be a substance that tastes like the actual medicine and appears like it, as well. The placebo is a substance that will not have any therapeutic effect on the participant. The remaining half of the participants are given a placebo. In this method, researchers provide some participants with the actual medication. Both the groups are administered with different experimental/control stimuli, without any of the participants knowing which group they belong in.Ī double-blind experiment is very useful, particularly when one is testing a brand-new medication. a control group and an experimental group. The image shows how participants are divided into two sections, i.e.
It removes all the room for errors and makes the circumstances such that there is no bias in the experiment. These strategies are relied upon, for different kinds of research. Single, double, and triple-blinding are the most commonly used methods, as a blinding strategy. This is done in an effort to remove the possibility of bias in the experiment.Ĭoncealing the information on treatment allocation from an individual is done to maximize the accuracy of research results.
Double-blind experiments are those in which these individual participants on whom the experiment is being performed, as well as the researchers in the experiment, are not aware of experimental treatments that the participants are being given. In certain experiments, it is essential to create scenarios which inhibit a researcher’s or a subject’s bias coming into play and interrupting the process of obtaining unbiased, factual results.
