Overview
The Big Five and Dark Triad are complementary frameworks. Big Five captures personality broadly across five major traits; Dark Triad zooms in on three socially aversive ones. They overlap statistically but answer different questions.
When to Use Each
Big Five
Use when you want a broad personality picture — the five traits cover most variance in adult personality. Best for general self-assessment, hiring, and clinical conversation.
Dark Triad
Use when you specifically care about socially-aversive traits. Useful for research, interpersonal conflict analysis, or studying patterns the Big Five doesn't directly probe.
Both
They're complementary. Dark Triad fills in detail in the corner of personality space the Big Five (specifically low Agreeableness with high Narcissism) doesn't fully resolve.

Frequently Asked Questions
Are Dark Triad traits part of Big Five?
Mostly low Agreeableness, low Conscientiousness, high Neuroticism. But the specific patterns of manipulation, grandiosity, and callousness are richer than the Big Five resolves.
Can someone be high on Big Five and Dark Triad?
Yes — Dark Triad correlates with high Extraversion (especially the Narcissism component) and sometimes high Openness. The traits aren't all 'bad'.
Which predicts behaviour better?
Big Five for general behavioural prediction; Dark Triad for socially-aversive behaviour specifically. Dark Triad has incremental validity over Big Five for predicting workplace harassment, infidelity, and manipulation.
Are these the same as personality disorders?
No — both measure sub-clinical traits. Personality disorders are clinical entities defined by impairment, not just trait elevation.
Which has more research?
Big Five has decades more. Dark Triad is newer but well-validated since 2002.
Should I take both?
If self-knowledge matters to you, yes. They paint different pictures.
