Drug ads often warn of serious side effects, from nausea and bleeding to blindness, even death. New research suggests that, rather than scaring consumers away, these warnings can improve consumers’ opinions and increase product sales when there is a delay between seeing the ad and deciding to buy or consume the product.

“Messages that warn consumers about potentially harmful side effects — presumably with the intent to nudge them to act more cautiously — can ironically backfire,” says psychological scientist Ziv Carmon of INSEAD in Singapore.

Predictably, participants who had the opportunity to purchase the cigarettes soon after seeing the ad bought less if the ad they saw included the warning.

In contrast, participants who were given the opportunity to purchase the cigarettes a few days later bought more if the ad included the warning. The same outcome emerged when the researchers ran a similar experiment with ads for artificial sweeteners.

According to Carmon and his colleagues, the warnings backfired because the psychological distance created by the delay between exposure to the ad and the decision to buy made the side effects seem abstract—participants came to see the warning as an indication of the firm’s honesty and trustworthiness.
