The sixteen types

Full profiles: how each type works, loves, stalls, and grows, with the cognitive function stack the big test sites leave out.

INTJ

The Planner

You think in systems and prefer to work out the whole model before you say a word about it.

Full profile

INTP

The Theorist

Your mind runs on questions, not answers, and you'll follow one down three unrelated tangents before you notice you've left the original topic behind.

Full profile

ENTJ

The Chief

You walk into a stalled meeting and, within five minutes, have assigned the open questions to specific people with dates attached.

Full profile

ENTP

The Brainstormer

You can generate ten angles on a problem before anyone else has picked one, and you enjoy arguing a position you don't even hold just to see if it survives contact.

Full profile

INFJ

The Compass

You read the mood shift in a room before anyone says a word about it, and you can usually tell when someone's answer doesn't match what they're actually feeling.

Full profile

INFP

The Conscience

You measure a decision against a private sense of right and wrong before you measure it against anything else, and a choice that's efficient but feels wrong will sit badly with you for days.

Full profile

ENFJ

The Mentor

You clock how everyone in a room is doing within the first five minutes, and you'll adjust what you say based on who needs encouragement and who needs a push.

Full profile

ENFP

The Catalyst

A stalled, awkward conversation snaps back to life the moment you jump in, usually within the first two minutes.

Full profile

ISTJ

The Auditor

You do what you said you'd do, on the date you said you'd do it, and you assume other people will too until they prove otherwise repeatedly.

Full profile

ISFJ

The Safekeeper

You remember that a coworker's mom had surgery last spring and ask about her recovery without being prompted.

Full profile

ESTJ

The Organizer

A disorganized situation gets roles and a plan assigned within minutes of you showing up, because an unclear plan bothers you more than most people can understand.

Full profile

ESFJ

The Host

You notice who wasn't invited and fix it before the event happens, because keeping a group connected feels like your job even when nobody assigned it to you.

Full profile

ISTP

The Troubleshooter

You stay quiet in a crisis while everyone else is talking, then you're the one who actually fixes it, hands-on, without narrating what you're doing.

Full profile

ISFP

The Quiet Original

You have a strong, specific sense of what looks and feels right, and you'll quietly redo something three times until it matches what's in your head, without explaining why to anyone watching.

Full profile

ESTP

The Doer

You read a room physically, the posture and the energy shift, before most people have consciously registered anything's changed.

Full profile

ESFP

The Live Wire

You bring energy into a room just by walking into it, and a flat, quiet gathering will not stay flat for long once you're there.
