How the test works

The test is built on Carl Jung's theory of psychological type and the four-scale model that grew out of it. Sixty-four statements measure the four scales, half worded toward each side so that agreeing with everything does not push a result. Your answers on a seven-point agree–disagree scale add up to a score for each scale, which sets the letter and the percentage in your results. Statements appear in a different order for every test taker.

Answer-quality checks

Eleven more statements, plus the timing and pattern of your answers, check whether the result can be trusted. The test looks at reading pace, attention, consistency between statements that mean opposite things, long runs of identical answers, agreement with everything, and claims of perfection. If the answers fail, no type is reported. Scoring happens on the server, so a result cannot be edited in the browser, and every results link points to a result the server actually scored.

What the percentages mean

A score near 50% means you use both sides of that scale about equally. A score of 80% or more means a clear, consistent preference. The percentage shows how consistently you answered, not how skilled you are.

Is this a clinical assessment?

No. Constant Refinement is a self-reflection tool. It is not a diagnostic, hiring or clinical instrument. Results describe preferences, and people of every type succeed in every field.
