MINI-IPIP · 20 STATEMENTS · ABOUT 4 MINUTES

Five dials, not one box.

The Big Five is the trait model most personality researchers use. Rate 20 short statements about yourself and see where you sit on each of the five scales. No sign-up, nothing saved.

What the Big Five is, in short

The Big Five describes personality as five independent traits: openness, conscientiousness, extraversion, agreeableness and neuroticism. Everyone has some amount of each, so your result is five positions on five scales, not a type.

The model came from analysing the words people use to describe each other: when thousands of adjectives were grouped statistically, the same five clusters kept appearing across languages. Half the statements here are reverse-scored, so agreeing with "I keep in the background" lowers your extraversion score.

The Mini-IPIP is too short to score facets. Longer questionnaires such as the 120-item IPIP-NEO report all 30.
40–60%of the differences between people are geneticTwin studies put the heritability of each Big Five trait in roughly this range. The rest comes from experiences that aren't shared within a family.3

Personality is how you tend to act. Reasoning is a different scale.

Of the five traits, only openness is linked to IQ, and only modestly. Our full test measures reasoning directly: 60 questions, about 30 minutes.
