“This is the DISC wheel. It is based on the behav-
ioral model developed by William Moulton Marston.
Marston was an interesting guy. He was a Harvard-
educated psychologist and PhD. In 1928, he wrote The
Emotions of Normal People, which describes the DISC
language that we will be discussing today. He also
developed the rst lie detector test and, best of all, he
was the creator of the Wonder Woman comic book
character. Who can remember her magic power?”
“Oh, I know! Her magic lasso and her bracelets!”
came the response from one of the participants.
“Not just a magic lasso, a lasso of truth!” shared
Carlos, Dave’s close friend and second in command. “I
had no idea it was related to DISC or to a lie detector,
but come to think of it, it actually makes sense.”
“He was a pretty fascinating guy,” continued Charles.
“William Moulton Marston developed the DISC lan-
guage, which is based on people’s observable behav-
iors—what can be seen by others. DISC doesn’t explore
why people do what they do, or whether they’re good
at what they do, or their intelligence. It only assesses
how they are observed. So if I’m sitting down on a
park bench, I can observe the people around me and
make some guess as to their DISC behavioral style. And
again, the purpose of doing this is to be able to better
coordinate action and collaborate with others.
“Marston’s model looks at people’s behaviors as they
relate to four factors: how they solve problems, how
skilled they are at relating to people, the pace at which
they work, and their need for processes or procedures.
