What is Big Five?
The Big Five (also called OCEAN) is the most scientifically validated personality model, measuring Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Multiple versions exist online, from academic to commercial.
You rate how much you agree with statements about your behavior and preferences. Your responses are scored on five continuous scales from low to high for each trait.
The five Big Five traits in Opinion DNA
Opinion DNA scores all five Big Five traits on the same 0 to 100 scale it uses for everything else: openness, conscientiousness, extraversion, agreeableness, and neuroticism. Each one has its own page explaining what high and low scores look like.
The other 43 dimensions sit next to them. The Dark Triad, such as Machiavellianism, extends the personality layer, while the values and meta-thinking layers cover what you care about and how you reason, which is where Big Five scores tend to leave people with follow-up questions.
