A step-by-step demonstration of the manipulation procedure.
A. Participants indicate the direction and strength of their voting intention for the upcoming election, and rate to what extent they agree with 12 statements that differentiates between the two political coalitions. Meanwhile, the experimenter monitors the markings of the participants and creates an alternative answering profile favouring the opposite view.
B. The experimenter hides his alternative profile under his notebook.
C. When the participants have completed the questionnaire, they hand it back to the experimenter. The backside of the profile is prepared with an adhesive, and when the experimenter places the notebook over the questionnaire it attaches and conceals the section containing the original ratings.
D. Next, the participants are confronted with the reversed answers, and are asked to justify the manipulated opinions.
E. Then the experimenter adds a color-coded semi-transparent coalition template, and sums up which side the participants favor.
F. Finally, they are asked to justify their aggregate position, and once again indicate the direction and strength of their current voting intention.
