How this test is made

MyEnergyType is built and run by FLOWLAB, a one-person studio in Seoul. The research, the questions, the writing, and the code are all one person's responsibility — so no sentence here hides behind anonymity. Questions are always welcome at [email protected].

The test is 40 questions on a five-point scale — ten for each of the four temperaments (Expressive, Driven, Reflective, Steady). Instead of abstract personality statements, the questions ask about concrete behavior in four scenes of life: among people, when things get moving, time alone, and in your relationships.

Your highest-scoring temperament (primary) combines with your second (secondary) to give one of twelve types. Two people who share a primary can carry very different energy depending on what comes second — that's why the pairing matters.

This is not a clinical diagnostic tool, and it does not measure the whole of who you are. It measures one thing: the pattern of where your energy fills up and where it leaks.

A type is not a box to put you in; it's a lens to start observing yourself with. If your result feels wrong somewhere, trust that feeling — you are always bigger than your type.

This test's roots go back 2,500 years to Hippocrates' observation of four temperaments. By today's science, the four-humors theory doesn't hold. But the observation at its heart — that people are born with different response patterns — was exactly right. We chose not to sell the theory as authority, and instead to retell that observation in modern language.
