And growing.
Everyone has habits of mind: what they notice first, how they weigh a decision, what drains them. OnType puts names to those habits so you can understand yourself, and the people you live and work with, a little better.
A short code for how you tend to direct your energy, take in information, make decisions and organize your life.
See all 16 types
Each type is built from cognitive functions: mental processes, like introverted intuition (Ni), that explain why the letters fit.

Relationships
Every type has three key pairings. Pick a type to see its golden, silver and pedagogue partners, compare their functions side by side, then read how each pair communicates, clashes and grows.
Fully compatible functions. Each of you uses the same functions in the opposite direction, so communication flows most easily.
Read this pairing SilverA lot in common, with a different approach. You understand each other easily, but tend to tackle things in different ways.
Read this pairing PedagogueA learning pair. Each of you is strong where the other is still growing, so you can teach each other a lot.

Typing sessions
Plenty of people are at first. A test can only measure how you describe yourself, and it's easy to answer as the person you'd like to be rather than the one who usually shows up.
In a one-on-one session, James works through your cognitive functions with you, looking at how you take in information and how you make decisions. The aim is to land on a type you can explain in your own words.
