DISCUSSION
• The 40-item SD3 has an acceptable factor structure with solid internal consistencies for each subscale.
• SD3 scales are highly correlated with the original D3 measures and evenly predict the facets of the those original measures.
• The locations of the SD3 in the Interpersonal Circumplex match those of the original scales
• Among the SD3, overclaiming correlates highest with narcissism , psychopathy to a lesser extent, and Mach not at all , thereby replicating previous findings using original measures (e.g., Paulhus & Williams, 2002).
• Using a behavioral indicator, Machiavellianism was positively associated with delay of gratification whereas psychopathy was negatively.
• In sum, the SD3 inventory provides a short but reliable instrument that demonstrates predictive, criterion, and concurrent validity.

Participants on MTURK are given the option for a bonus. Participants were asked 2 questions:
(A)Would you like to keep your bonus or donate it to American Red Cross?
