Hamilton and Gifford (1976) found the “illusory correlation”, which means that the minority group is more special and unique than the majority group and gives the minority group a negative evaluation. According to this phenomenon, the negative evaluation causes the negative behaviors more relative to the minority group membership. Our team guesses this stereotype of the fictitious groups maybe exist in the real groups. For example, the phenomenon maybe occurs in the evaluation of the country. To remove the error by the individual attitude to the country, we chose two countries by the pilot study which asks the subjects to select the degree of preference to some countries from 1 to 7. Another pilot study was to choose the positive and negative sentences which describe the countries. In the experiment, we operated the number of positive and negative sentences to the two groups that are the majority and minority group defined by the number of sum of descriptive sentences, but fixed the percent of two typical sentences, to influence the attitude to the two countries of subjects. As a result, there is no significant between the two groups in the number of recall negative sentences. But in another respect, in the percent of negative recall sentences, minority groups are significantly more than majority groups by studying the percent of discrepancy between the real number and data.
