[List of side effects for a fake prescription drug in a parody of a TV ad.] Medications come with long lists of potential side effects. Now a study finds that the litany of unpleasant consequences does not deter prospective purchasers. In fact, those warnings might actually increase drug sales.
For the study, subjects were shown two different versions of ads for three different products: cigarettes, artificial sweeteners and medications.
One version of the ads clearly warned of potential perils—for example, hair loss, weight gain or stroke. The other set of ads were warning-free.
Subjects who saw ads with warnings were initially less likely to buy the products. But when surveyed again some time later, they were actually more likely to make the purchase than were those who saw ads without the warnings. The study is in the journal Psychological Science.
