1. Think of a real-life example of the principle of scarcity being used in a persuasive message. Were you the one trying to persuade someone, or were you the receiver of the scarcity message? Was the message effective? Discuss your thoughts with a classmate.
2. Do you think the principle of consensus often works-are people often persuaded to buy things because other people own that item, or are going to buy it? Are you susceptible to this kind of persuasion? Think of some examples and discuss them with classmates.
3. Do people always use reason to make decisions? Support your opinion and discuss it with classmates.
4. Make a list of five or six people you choose to associate with-friends, neighbors, and coworkers, for example. Next to each person's name, write the characteristics you have in common with that person. Do you find that the principle of liking holds true in your choice of associates? Why or why not? Discuss your findings with your classmates.
