The Big Five Personality Traits

The Big Five (OCEAN) is the most widely used personality model in psychology research. It describes personality on five broad traits, each a spectrum rather than a type.

Where the Big Five comes from

The model grew out of the lexical approach: researchers analyzed the words people use to describe each other and found they cluster into five broad factors. Lewis Goldberg's work on these factors produced the public-domain IPIP markers our test uses, and McCrae and Costa found the same five-factor structure across many cultures.

Frequently asked questions

What are the Big Five personality traits?

Openness to experience, conscientiousness, extraversion, agreeableness and neuroticism, often remembered as OCEAN.

Why do psychologists prefer the Big Five to Myers-Briggs?

The Big Five scores each trait on a continuous scale instead of sorting people into types, and its scores are more stable on retest and better at predicting outcomes in research.

Do Big Five traits change over time?

They are fairly stable in adulthood but shift gradually: on average, people become more conscientious and agreeable and less neurotic as they age.
