In order to increase the response rate to mail questionnaires, researchers sometimes include a dollar bill or other monetary incentive to reward the respondent for his or her cooperation.

Could there be occasions where a relatively large reward-e.g., the inclusion of a $20 bill with a short questionnaire-might end up exerting a biasing influence on the answers the respondent provides? If so, give a real or hypothetical example of such an occasion.
