I t has been found in several laboratory studies (e.g., Dustin & Davis, 1970) that in team competition members tend to evaluate their own team product more favorably than that of the competing team. The purpose of this smdy was to find out whether similar bias existed in a real competition, a campus card contest. Ss were 44 college men and women who had paid $2 a pair to enter a contest in a card game called pitch, for which the first prize was $35. Two student Es, only one of whom took part in planning the study, approached teams as soon as their first match was finished, announcing, Say, I'm doing a little project for a class. Would you tell me what you really think the score would be if you played that team once again? Each of the four Ss at the table was pressed for an answer. Each E approached six tables but missed several players who left too quickly to be questioned. All matches that ended at a time when both Es were busy interviewing were lost to the study. A team was categorized as predicting a win or a loss if both partners predicted accordingly or if the only partner available did. For El, all six of the winning teams predicted they would win another game, while five of the six losing teams predicted that they, themselves, would win. The Fisher exact probability test shows the difference between these two distributions to be significant at the .05 point. For E-, all six of the winning teams predicted they would win again, while three of four losing teams predicted that they, themselves, would win. The two members of a fifth losing team were dropped from the analysis because they split their predictions, and both members of a sixth losing team departed too quickly to be questioned. The Fisher test showed the difference between these two distributions to be significant at the .05 point. It appears that rather extreme bias may occur in group competition outside the laboratory, at least in this particular type of contest. This is not a case where one team predicted they would perform slightly less poorly than cheir opponents predicted they would. Rather, in a majority of cases, both winning and losing opponents predicted that they, themselves, would win if another game were played.
