In your textbook highlights various techniques used in persuasive messaging, including foot-in-the door, low-ball, door-in-the face, reciprocity, etc. After examining all the techniques, choose three to address in your discussion. For each of the three, describe the processes involved, and explain why such techniques are successful in persuading certain audiences, but are likely to fail with others. In addition, examine the overall resistance to persuasion. Although they may be undesirable, are we more vulnerable to these messages than we think?
