Question

A survey of physicians found that some doctors give a placebo to a patient who complains of pain for which the physician can find no cause. If the patient's pain improves, these doctors conclude that it had no physical basis.

The medical school researchers who conducted the survey claimed that these doctors do not understand the placebo effect. Why?

Because it is possible that there is a physical basis to the claims of the patient, but the placebo helped him. Because placebo can be used reliably only in properly designed experiments. Because placebo effect has impact only on groups. None of the above.
