We are often happy to do favors for other people when they have a particular need. For example, we are more willing to let someone use a photocopier when they ask, “Can I go in front of you, because I am in a rush?” than when they give no reason: “Can I go in front of you?” Some researchers believe that simply giving a reason—using the word “because”— may be enough to trigger this giving behavior, even when the reason is not a very good one. An experiment was done in which 60 people who were about to use a Xerox photocopy machine were approached (Langer et al. 1978). In 30 cases (randomly assigned; call these the “request-only” group), an investigator asked, “May I use the Xerox machine?” Eighteen of these people allowed the investigator to go first. In the other group of 30 people (the “bad-reason” group), an investigator said, “May I use the Xerox machine, because I have to make copies?” Of the 30, 28 allowed the  investigator to go first. Test whether the bad-reason approach is better or worse than the request-only approach.
