Effects of warning and information labels on consumption of full-fat, reduced-fat, and no-fat products.
通过品尝实验发现，信息标签比警告标签更能减少人们对全脂产品的选择，因为警告标签可能引发逆反心理。
Participants in a taste test study were randomly assigned to 1 of 3 groups: warning label (e.g., "In this product, 90% of the calories come from fat.Warning: The U.S. Surgeon General has determined that eating high fat food increases your risk of heart disease."), information label (e.g., "In this product, 90% of the calories come from fat."), and no label.Participants rated how much they wanted to taste full-, reduced-, and no-fat cream cheeses, and they chose 1 type to eat.People in the warning-and no-label groups wanted to taste the full-fat product more than those in the information-label group.People in the warning-and information-label groups were less likely to eat the full-fat product than those in the no-label group.People reacted to the warning label but avoided the full-fat product.For products with credible and familiar risks, information labels may be more effective than warning labels because they don't arouse reactance.So great is man's hunger for forbidden food!
