Problem: Daisy is asked to self-report the number of cappuccinos she consumes in a day. Since she knows that cappuccinos aren't good for your health, she reports only drinking one per day, even though she normally drinks two or three a day. Why would Daisy under report how many cappuccinos she drinks? a. Researchers failed to account for participants with poor memory recall b. Daisy is worried about the researcher thinking negatively about the number of cappuccinos she drinks a day (i.e., her social desirability) c. Self-report is not a reliable method d. Daisy is influenced by subject bias
