We were able to confirm our hypothesized effect. Asking people to answer quickly causes them to give more socially desirable responses (M = 5.069, SD = 2.55) than asking them to answer slowly (M = 4.722, SD = 2.358; *F* (1, 1496) = 7.559, *p* = .006, **d** = .142, 95%CI = .04 to .243).
Switching the socially desirable response to the left or right option did not change the results, nor was there an interaction with time pressure and left or right answers (both ps > .48).
Thus, to answer the question: “What does making people respond quickly do?” we can answer that the evidence here suggests speeded judgments causes an increase in socially desirable responding. When people were asked to answer quickly or slowly there was no effect of whether answers were on one side of the screen or another. Speeded judgments affect social desirability.
