Randomly assigning participants to control and treatment groups is the most scientifically sound method of conducting a clinical trial as it helps to eliminate bias and ensures that the differences observed between the two groups are due to the treatment, rather than other factors. Eliminating placebo conditions is not always possible or ethical, as placebos are often necessary to establish the efficacy of a treatment. Allowing subjects to volunteer for the control group can also introduce bias and is not a reliable method of selecting participants. Conducting a case study of an experimental treatment is not as rigorous as a randomized controlled trial and does not provide the same level of scientific evidence.
