Here's an “introduction to DISC profiling”, and “Understanding DISC”. What DISC tells about anyone is the “four factors of an individual's behaviour: Dominance, Influence, Steadiness and Compliance”.
What it says about me: High Dominance and Compliance. It's interpretations can be found here and here.
Briefly: “This 'U'-shaped profile is not uncommon. It represents a highly formal and structured individual with a forceful and blunt style. This type of person believes in getting things right, and is rarely afraid to state their mind robustly and directly. Of all possible DISC profiles, this style probably represents the least forthcoming in personal or emotional matters; individuals of this type tend to be remote and somewhat isolated, preferring to keep their own counsel.”
With regards to common abilities: “This is a behavioural style motivated by achievement and efficiency, as are all styles containing a high level of Dominance. In this case, however, this is modulated by the presence of a high Compliance factor, which also lends the character an interest in detail and precision. A noticeable element of this particular type, for example, is their tendency to correct other people when they make errors, even to the point of highlighting mistakes that others might regard as trivial or unimportant”.
UPDATE: 5 Jan 2014I've discovered a file - An INTP Profile.htm dated 30 Jul 2002, which meant that I discovered I'm an INTP in 2002.
Today, I did my Jung Topology Tests again, and I was graded the following: YOUR TYPE I N T P Strength
