The Big Five — and 43 dimensions beyond
Get your Big Five scores plus the Dark Triad, moral foundations, cooperative virtues, personal values, and cognitive biases. All with an AI-generated report that ties everything together.
The Big Five is a great start
The Big Five personality model (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) is the most scientifically validated framework in personality psychology. It's a genuine achievement of psychological science. Opinion DNA includes all five traits — and then keeps going.
What comes after the Big Five
Opinion DNA adds: Dark Triad traits (Machiavellianism, Narcissism, Psychopathy) — the shadow side of personality. Emotional regulation and life satisfaction. 5 moral foundations (Care, Fairness, Loyalty, Authority, Purity). 7 cooperative virtues (Family, Group, Reciprocity, Heroism, Deference, Equity, Property). 10 personal values (Power through Security). 12 meta-thinking elements including cognitive biases and primal world beliefs. That's 48 dimensions total — the Big Five plus 43 more.

Frequently asked questions
If the Big Five is so good, why do I need more?
The Big Five tells you how you tend to behave. It doesn't tell you what you value, what moral foundations you prioritize, or how you process information. Two people with identical Big Five profiles can have radically different values and cognitive patterns. The Big Five is necessary but not sufficient for comprehensive self-understanding.
Are your Big Five scores compatible with other Big Five tests?
Yes. Opinion DNA uses validated Big Five scales, so your scores are comparable to other Big Five implementations. You'll just get 43 additional dimensions on top.
