Attitudes and behavior

So far, our discussion of attitudes has assumed that there is a close relationship between attitudes and behavior. Attitudes should predict behavior. Otherwise, why would anyone care? If attitudes didn't predict behavior, for example, would advertisers care to spend millions of dollars to change them? Probably not, given that they are ultimately concerned with whether someone actually purchases their products. But how close is the relationship between attitudes and behavior?

In 1934, Richard LaPiere <REF>traveled the western part of the United States with a Chinese couple. At the time, prejudice against Chinese minorities was quite common and you might expect that they encountered much discrimination. In fact, they didn't. Although they visited more than 250 hotels, restaurants, and campgrounds, they were refused service only once. After the trip was over, LaPiere wrote to all of the places they had visited and asked them if they would accept "members of the Chinese race as guests." Half of the establishments responded and 90% of them said they would not allow Chinese guests. In other words, their actions bore little correspondence to their attitudes.

Of course, there are several possible explanations for LaPiere's results. It's not clear, for example, whether the people who filled out the opinion surveys were the same people who made decisions at the front desks. Similarly, the surveys were completed six months after the visits were made. It is always possible that attitudes changed during that period of time. But the evidence for attitude behavior inconsistency is not limited to LaPiere's study. In a sweeping review of the attitude literature, Alan Wicker<REF> (1971) found numerous examples where attitudes failed to predict behavior. From church attendance to discrimination, he found little evidence that attitudes predict behaviors. Why?
