The leader of the Socialists in the Dutch Parliament and his Liberal opponent participated in this realistic experiment. Identical TV interviews with the two politicians were recorded and shown to subjects of both parties. The intensity of delivery was also varied: emotional versus rational. Our findgins indicated that the experimental interveiw changed the attitude of the subjects. In addition, support was found for a second hypothesis: Attitude change was greater for the attractive source from the same party than for the less attractive source from the opposite party. Furthermore, our expectations were confirmed that attitude change would be greater with high than with low discrepancy. Although the intensity of delivery did have an effect on the credibility of the source–the emotional delivery scored lower–no effect on attitude change was found.
