Not all media influence is necessarily bad. Take the kids who took part in a study at Cornell University’s Food and Brand Lab recently. One day during the study, researchers asked participating children whether they’d like to eat French fries or apple slices. The kids, without exception, chose the fries. The following day, researchers gave their subjects the very same choice—but they posed the question differently: What choice Batman would make? Nearly half the kids—about 45 percent—opted for the apple slices. (Cornell University)
