Social norms approach

The social norms approach, or social norms marketing, is an environmental strategy gaining ground in health campaigns. While conducting research in the mid-1980s, two researchers, H.W. Perkins and A.D. Berkowitz, reported that students at a small U.S. college held exaggerated beliefs about the normal frequency and consumption habits of other students with regard to alcohol. These inflated perceptions have been found in many educational institutions, with varying populations and locations. Despite the fact that college drinking is at elevated levels, the perceived amount almost always exceeds actual behavior. The social norms approach has shown signs of countering misperceptions, however research on changes in behavior resulting from changed perceptions varies between mixed to conclusively nonexistent. The social norms approach is founded upon a set of assumptions that individuals incorrectly perceive that the attitudes or behaviors of others are different from their own, when in reality they are similar. This phenomenon is known as pluralistic ignorance. It is largely because individuals assume the most memorable and salient, often extreme, behavior is representative of the behavior of the majority. This may lead individuals to adjust their behavior to that of the presumed majority by adhering to the pseudo-norms created by observing such memorable behavior. These exaggerated perceptions, or rather misperceptions, of peer behavior will continue to influence the habits of the majority, if they are unchallenged. This means that individuals may be more likely to enact problem behaviors and suppress healthier practices, making support for healthy behaviors much less visible at an aggregate level. This effect has been documented for alcohol, illegal drug use, smoking, other health behaviors, and attitudes, such as prejudice. A phenomenon known as false consensus is closely related to the idea of pluralistic ignorance, and refers to the incorrect belief that others are similar, when in reality they are not.
