1. A pharmaceutical company developed a new drug to relieve hallucinations experienced by schizophrenics. A researcher contacted four psychiatrists, asking two of them to administer the drug to their patients who had hallucinations and asking the other two psychiatrists to administer a placebo to their patients who had hallucinations. (Of course, to control experimenter expectancy effects, the psychiatrists did not know whether their patients received the drug or the placebo.) Two weeks later, all patients were evaluated by an independent team of psychiatrists. Analyses of the data showed that patients who received the drug were experiencing fewer hallucinations than patients who received the placebo, and the company moved forward to market the drug.
