Introduction - History/Validation
The DISC profile system has its roots in
time-tested and proven theories dating back to the Swiss Psychologist Dr. Carl Jung
and William Marston Ph.D. from Harvard University. Both of these renowned
scientists were creating their theories in the 1920's. Their work branched into
different specialties (Jung studied dysfunctional personalities while Marston
focused on the behavior of normal people). DISC has followed Marston's model
supported by his famous book, 'The Emotions of Normal People', a best-selling
classic for many years.
Validated accuracy is 91% - the DISC is as high as
any assessment of this type in the world! For more than twenty years, it has
unlocked the door to productive communication and relationships for over 4
million people, worldwide. Extensive research and international validation
