HISTORY OF DISC
DISC's history as a personality test goes back to its development by William Marston in the 1920's. There are some core ideas behind the DISC profiler, though, that reach back much further: indeed, certain principles can be traced back as far as ancient Greece. Here we take a brief journey through the history of ideas that led to the modern DISC personality assessment technique.
DISC is a simple, practical, easy to remember and universally applicable model. Based on the research of Dr. William Moulton Marston, DISC is the most widely-used behavior identification tool of its kind, supported by decades of research and continuous validation.
It focuses on individual patterns of external, observable behaviors and measures the intensity of characteristics using scales of directness and openness for each of the four styles:
Dominance, Influence, Steadiness, and Conscientious.
