One question we get regularly is: “Why does DiSC have a small “i”?
Before we reveal the reason for the small ‘i’, it’s important to note that no company or publisher owns DISC Theory. DISC, the theory, was created by William Moulton Marston in the 1920s. While Marston developed a theory that helps us better understand human behavior, he never created a ‘DISC assessment.’
For this reason, there is a multitude of DISC-based assessments that go by a lot of different names; Everything DiSC, DiSC Classic, Extended DISC, Personal Profile System, Take Flight with DISC, and Tony Robin’s DISC Test, are just a few of the DISC-based products available.
Now, returning to the question, why does our version of DiSC have a small ‘i’? Those that know DiSC know that each letter stands for a particular DiSC Style:
- D-Style – Dominance
- i-Style – Influence
- C-Style – Conscientiousness
- S-Style – Steadiness
So is it that those with the i-Style are less powerful or less significant than the D-Style, S-Style, or the C-Style? Well, the truth of the matter is no, that is not the case. There is no deep dark research based reason for the small i. And no, certification or advanced training is not required to be a keeper of the secret of the small i.
The Story of the Small 'i'
It was once published by a small company called Performax. During this time, a funny thing happened as they were trying to release their premier product, the DISC Personal Profile System (a precursor to the DiSC Classic Paper Profile). Performax was a very small organization, and they didn’t have much room for errors.
They placed an order for the original printing of the DISC Personal Profile System, but when they got their assessment booklets back from the printer, there was a typo. A small, tiny, little typo. A typo the size of an “i.”
Yes, that is right. The printer did not capitalize the I in DISC. Performax decided to use this mistake and copyright DiSC to use it to market their DISC Instrument. So that is how DISC got its small i. When you see the ‘small i’ version of the DISC profile, you know it was published by Wiley Publishing, or it is in violation US copyright laws.
