TIPI-10
The TIPI-10 is the shortest validated Big Five personality test ever published, 10 items, 1 minute, all five OCEAN traits. Developed by Gosling, Rentfrow & Swann at UT-Austin in 2003, it is used in thousands of peer-reviewed studies. Free, no signup, instant OCEAN profile.

TIPI (Gosling 2003)
- Your full Big Five (OCEAN) profile in about a minute, 10 items, no signup
- Scores on all five dimensions: Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism
- Your dominant trait and the trait you score lowest on, with plain-English readouts
- A peer-reviewed instrument used in thousands of academic studies, not an internet quiz
Yes. The TIPI is in the academic public domain, its authors (Gosling, Rentfrow & Swann, 2003) explicitly state on the UT-Austin lab page that anyone can use it for any purpose without permission, including commercial products. JobCannon runs the test free with no signup, no email gate, and no paywall on the basic result. The premium upsell shown after the result is optional.
Less precise than a 50-item version, but more accurate than most people assume. The TIPI's 6-week test-retest reliability sits around r 0.72, and it correlates with the longer BFI-44 at r 0.65-0.87 across the five traits. Gosling et al. (2003) explicitly designed it for situations where brevity matters more than precision, survey studies, screening, and quick self-assessment. For percentile-grade accuracy, take the 50-item Big Five instead.
Five of the ten items (Critical/quarrelsome, Reserved/quiet, Disorganized/careless, Calm-emotionally stable, Conventional/uncreative) are reverse-keyed: agreeing with them lowers your score on the corresponding trait. This is a standard psychometric technique that helps catch yea-saying response bias and forces you to actually read each item. The scoring engine flips the reverse-keyed responses before averaging.
Same five dimensions (OCEAN), same theoretical framework, different item count. The TIPI uses 2 items per trait for a 1-minute snapshot; the Big Five-50 (IPIP-50) uses 10 items per trait for percentile-grade precision and a richer result page with archetypes, career fit, and trait-by-trait coaching. Think of TIPI as the entry tier, Big Five as the standard, and IPIP-NEO-120 (planned) as the deep dive.
