Question

Quizplus · Accepted Answer

Using a placebo control group can counteract the effect of demand characteristics, as participants may experience similar expectations and beliefs about the effectiveness of the drug, regardless of whether they receive the actual drug or a placebo. This can help ensure that any observed effects are actually due to the drug itself and not due to participant expectations or biases. The other strategies may have other benefits, but do not directly address the issue of demand characteristics.
