Self-deception and discrepancies in self-evaluation

Self-deception is an intricate psychological construct, grounded in relatively little empirical evidence as an in individual difference variable. The present research offers a direct test of one of the central scales of self-deception—the Self-Deception Enhancement (SDE) scale—by comparing explicit and implicit self-evaluations. Using the Affective Misattribution Procedure (AMP), participants (N = 150) reported about their implicit self-evaluation. These ratings were compared to explicit self-reports about self-evaluation. Results showed that higher self-deception was associated with a larger discrepancy between explicit and implicit self-evaluations. Specifically, higher self-deception was associated with a more positive explicit self-evaluation but with a more negative implicit self-evaluation. These findings offer one of the first direct tests of the SDE, supporting its viability.
