Note. Not all 70 items are depicted. Arrows represent loadings of all items on the general factor as well as the respective themes of D.

Figure 2. Category Response Curve for Item d_64 in D70.

Note. Item d_64 states “Success is based on survival of the fittest; I am not concerned about the losers.” Item d_64 showed the highest α value (1.92) across D70. Probability curves show the most likely item response category (1 to 5) across the continuum of D. The ordered curves show distinct peaks, indicating good discrimination between individuals.

Figure 3. Category Response Curve for Item d_9 in D70.

Note. Item d_9 is reverse coded and states “It is not okay to spread rumors, not even to defend those you care about.” Item d_9 showed the lowest α value (0.32) across D70. Probability curves show the most likely item response category (1 to 5) across the continuum of D. The unordered curves without distinct peaks indicate poor discrimination between individuals.
