Table 2. Sample Story, Experiment 1.

Brian had a physical exam scheduled with his doctor. When the day arrived, he had been having a sore throat for a couple of days. The doctor looked at it and took a throat swab. She told him, “I'm pretty sure it's just a minor throat infection. I've been seeing a lot of them recently, and yours looks like most of them. But given the amount of pain you're describing, there's also a small possibility that you have [a cold/throat cancer]. But let's see how the throat culture turns out. If it's positive, then I'll prescribe some antibiotics for you.” The rest of the physical went fairly well, except that Brian had put on 7 pounds, and the doctor told him to try to cut some fat out of his diet.
Questions
1. What is the probability that Brian will actually cut some fat out of his diet?
2. What is the probability that Brian will need to undergo surgery in the near future?
3. Why did Brian see his doctor?
4. What is the probability that Brian will have a fever in the near future?
5. What do you think Brian's throat pain is most likely caused by? (Please give only one answer.)
