Double-blind Control Experiment

Double-blind Control Experiment

A double-blind control experiment refers to an experimental technique used to ensure impartiality and clear errors emanating from bias. It is also an empirical study whereby information about the test is concealed from the participant so that it can reduce bias until when the results are known. However, it is an experiment whereby neither the participator nor the experimenters know about who is getting the treatment (Wells et al., 2015). The technique is used to prevent any element of biasness in research outcomes. In a double-blind control experiment, both the participator and the individual conducting the experiment do not know the person receiving the experimental treatment. The experiment aims to provide an unbiased outcome. Biasness in an investigation might be intentional; hence double-blind control experiment solves the challenge.

A double-blind control experiment is used mostly used in forensics, medicine and physics studies. Most scientific experiments employ the idea of a double-blind study to eliminate biasness in the end results (Fridriksson et al., 2011). For instance, a double-blind control experiment is used in the study of drugs by formulating both investigational drugs and established or control drug to show identical color. To attain exact results from the massive data in physics studies, the double-blind experiment is inevitable. A double-blind control experiment is crucial when conducting forensic studies of criminals. The shift to sophisticated criminal activities has desperately called for the use of the double-blind control experiment in police departments. The application of the experimental technique has improved security in our society because of easy identification through forensic studies.

In conclusion, it is evident that results from a double-blind control experiment cannot be manipulated since no influence. The procedure involved in the experiment reduces the possibility of biasness. The double-blind control experiment is best suited for medical researchers and forensic studies.
