Question

Quizplus · Accepted Answer

The researchers use a placebo, which is a type of inert substance or treatment that is indistinguishable from the actual treatment in order to control for the placebo effect. The control group receiving sugar pills provides a comparison for the experimental group that is receiving the new anti-anxiety drug. This allows the researchers to determine whether any observed differences between the two groups are due to the drug or to other factors, such as the placebo effect.
