*Hypothesis* We predict that being asked to answer psychological questions causes an increase in socially desirable responding compared to being asked to answer the questions slowly. To test this, we will administer the short form of the Marlowe-Crowne Social Desirability Scale and instructed participants to answer the questions either quickly or slowly. This would be important for many experiments that have used speeded judgments as a manipulation of cognitive load. We will collect 1500 participants drawn in a stratified way with unequal probabilities of selection, so that the people who complete each survey will resemble the nation's adult population (according to the most recently available Current Population Survey, conducted by the U.S. Census Bureau) in terms of gender, age, education, ethnicity (Hispanic vs. not), race (allowing each respondent to select more than one race), region, and income. Participants who took the pilot test or the confirmation of this study will not be invited to take this self-replication.
