DiSC Behavioral Styles from a Historical Perspective
The Ancient Greeks came up with the concept of the four temperaments. Hippocrates said, your style is determined by your body fluids: Yellow Bile, Blood, Phlegm, and Black Bile. This theory is remarkably similar to our DiSC Profile used today. The four temperaments or DiSC Behavioral Styles which you occasionally see used today are:
- Choleric – Yellow Bile, corresponds to D
- Sanguine – Blood, corresponds to i
- Phlegmatic – Phlegm, corresponds to S
- Melancholic – Black Bile, corresponds to C
The 20th Century saw the beginnings of the formal study of Psychology. In 1923, a landmark work was published: Psychological Types, by Carl Jung. Jung gave us the terms Introvert and Extrovert, and he identified the four types as Sensing, Intuitive, Feeling and Thinking; which correspond to the four factors in the DiSC Model: D, i, S, C respectively.
Today studies of differences in people are abundant. In all theories, there seems to be one common thread – one factor – that even reinforces the more primitive studies. That is that behavior is observable, and it forms patterns. The four major patterns of behavior were identified by Dr. William Moulton Marston, in his book "The Emotions of Normal People," published in 1923.
Today, the most thoroughly developed, valid and reliable DiSC Behavioral Style instrument for measuring behavioral styles is the DiSC Personal Profile, now known as DiSC Classic by Inscape Publishing.
Always look for the "Original DiSC Profile" – the one with the small "i" – a trademark of Inscape Publishing.
