16 personality types vs the Big Five: what is the difference?

By My Inner · Updated 12 November 2026

In short: The 16 personality types model sorts people into one of 16 categories based on four either/or preferences. The Big Five describes personality as five continuous traits: openness, conscientiousness, extraversion, agreeableness and neuroticism (often shortened to OCEAN). Researchers generally favour the Big Five, while the 16-type approach is popular for its simple, memorable categories.

The 16 personality types approach

The 16-type approach grew out of Carl Jung’s theory of psychological types and was developed into a questionnaire by Katharine Briggs and Isabel Briggs Myers. It describes four dimensions: extraversion or introversion, sensing or intuition, thinking or feeling, and judging or perceiving. Your combination of preferences gives a four-letter type.

Its strength is accessibility: types are easy to remember, discuss and apply to communication and teamwork.

The Big Five (OCEAN) approach

The Big Five, also called the five-factor model, comes from decades of research that grouped descriptions of personality into five broad traits.

Openness: curiosity and interest in new ideas and experiences
Conscientiousness: organisation, reliability and self-discipline
Extraversion: sociability and energy in social settings
Agreeableness: cooperation, trust and consideration of others
Neuroticism: tendency to experience stress and negative emotion

Key differences

Type versus trait is the main difference. The 16-type model puts you in a category; the Big Five gives you a position on each of five scales. Most people sit somewhere in the middle of many scales, which a category can hide.

The Big Five is also more widely used in academic research, while the 16-type model is more common in popular self-development and workshops.

Which should you use?

If you want an easy-to-discuss framework for self-reflection, the 16-type model can be a useful starting point. If you want a model with more research behind it, look at the Big Five. Either way, treat results as descriptions of preferences and tendencies, not as fixed labels or predictions.

Common questions

Is the Big Five more scientific than 16 personality types?

The Big Five is generally preferred in academic personality research because it treats traits as continuous and has been studied extensively. The 16-type model is popular but is more often criticised by researchers.

Can I use both?

Yes. Many people find the 16 types easier to talk about and the Big Five more nuanced. They describe personality in different ways, so results will not map perfectly onto each other.
