The Quizmaster Study (Ross, Amabile, & Steinmetz, 1977) is a classic experiment that illustrates the fundamental attribution error. In the study, participants were randomly assigned to be either 'questioners' or 'contestants.' The questioners created difficult questions to which they already knew the answers, giving them a significant situational advantage. Despite this clear contextual influence, both the contestants and third-party observers attributed the questioners' performance to superior intelligence (an internal factor), thereby underestimating the power of the situation.
