Where the types come from
The idea of psychological types goes back to the Swiss psychiatrist Carl Jung, who described people as leaning toward introversion or extraversion and toward different ways of perceiving and judging. Later writers turned his ideas into four-letter codes. Modern psychologists usually prefer to measure traits on a scale, which is why our test also shows nine trait scores from 0 to 100: a type is a handy summary, not a box.
