What type are you?

This is a 16 Personality Types assessment based on Carl Jung's theory of cognitive functions. It measures where you fall on four fundamental dichotomies that shape how you perceive the world and make decisions:

The Quick version uses 12 questions (3 per dichotomy) for approximately 60% accuracy — enough to identify your likely type. The Deep version uses 24 questions (6 per dichotomy) for approximately 75% accuracy, adding nuance and reducing error from a single ambiguous answer. For the highest precision, Know Your Human analyzes behavioral patterns across 11 personality frameworks — no self-reporting needed, which eliminates the biases inherent in any questionnaire.

Most AI agents treat every person the same way — generic tone, generic pacing, generic advice. But people process information in fundamentally different ways. An INTJ wants efficiency, systems thinking, and direct answers. An ENFP wants possibilities, creative exploration, and room to riff on ideas. Giving the wrong style to the wrong person creates friction — even when the information itself is correct.

Knowing your cognitive type lets AI adapt its tone, pacing, decision support, and information density to match how you actually think. Instead of one-size-fits-all interactions, your AI becomes a tool that works with your natural wiring rather than against it. This is especially powerful for coaching, productivity, and communication tools where mismatched style kills engagement.
