Utility/Disutility in Dark Factor of Personality (D-Factor)

Utility/disutility in dark factor of personality (D-factor) are central to understanding shared core underlying traits of narcissism, psychopathy, and Machiavellianism. The D-factor is defined as a general disposition to maximize one’s own utility while disregarding, accepting, or actively causing disutility to others, often supported by self-justifying beliefs. High-D individuals aren’t defined merely by self-interest, but by a readiness to impose non-consensual disutility on others (lying, exploitation, bullying) and, in some cases, by spitefulness — tolerating small personal costs to cause greater harm to others. In extreme forms, others’ suffering itself can become a source of utility. At the same time, high-D individuals may behave cooperatively when it serves their long-term utility — avoiding punishment or maintaining reputation — highlighting that dark traits are strategic rather than impulsively antisocial. From this perspective, the D-factor involves three interlocking components:

• Maximizing individual utility: prioritizing personal gains such as power, money, pleasure, excitement, or status.
• Imposing or ignoring disutility to others: willingness to cause financial, psychological, or physical harm—or to remain indifferent to it—in pursuit of personal goals.
• Justification: adopting beliefs (entitlement, superiority, cynicism) that make harmful behavior feel acceptable or deserved.
