poor decision making. They approach college students at a bar, explain the study to them, and offer to pay

non-alcoholic beverages. The researcher then asks them to complete a short study of their decision making
ability. Many of the students given alcohol don't complete the study, or write in joke answers, so they throw
those results out. Afterwards, they find that there is no difference between the decision making capability of
the students who drank and those who did not.
