Open Four Temperaments Scales

This is an interactive version of the Open Four Temperaments Scales.


The idea of the four temperaments traces back to the Ancient Greek medical theory of the four senses of humor, which held that there were four fundamental bodily senses of humor (blood, yellow bile, black bile, and phlegm) and that illness was caused by an imbalance in these.

The terms sanguine, choleric, melancholic, and phlegmatic were coined by the Greek physician Aelius Galenus to describe the effect of the humor on personality. The four temperaments have not been a part of medicine or psychology for a hundred years, but remain popular in the writings of several prominent self-help and spirituality authors and the idea remains relatively well known.

The Open Four Temperament Scales were developed in 2014 by Eric Jorgenson using surveys of individuals who knew of the four temperaments and identified as one and selecting items that reliably predicted self-identification.
