I'm always interested in how our personalities affect what we do, think, and say. Now, there's a tool that uses the Myers-Briggs type indicator personality framework to analyze your writing.
Keirsey.com labels ESTP profiles "Promoters" and says "Clever and full of fun, Promoters live with a theatrical flourish which makes even the most routine events seem exciting." I guess that makes sense given that not all gadget reviews are inherently exciting and many need a bit of hyperbole to make them interesting.
But that ESTP seemed somewhat different than the profile M-B tests have generated for me in the past, so I self-administered the 72-question instrument here and came up with the more familiar INTJ. INTJs are described as follows (courtesy of Keirsey.com):
Rational Portrait of the Mastermind (INTJ)
All Rationals are good at planning operations, but Masterminds are head and shoulders above all the rest in contingency planning. Complex operations involve many steps or stages, one following another in a necessary progression, and Masterminds are naturally able to grasp how each one leads to the next, and to prepare alternatives for difficulties that are likely to arise any step of the way. Trying to anticipate every contingency, Masterminds never set off on their current project without a Plan A firmly in mind, but they are always prepared to switch to Plan B or C or D if need be.
Masterminds are rare, comprising no more than, say, one percent of the population, and they are rarely encountered outside their office, factory, school, or laboratory. Although they are highly capable leaders, Masterminds are not at all eager to take command, preferring to stay in the background until others demonstrate their inability to lead. Once they take charge, however, they are thoroughgoing pragmatists. Masterminds are certain that efficiency is indispensable in a well-run organization, and if they encounter inefficiency-any waste of human and material resources-they are quick to realign operations and reassign personnel. Masterminds do not feel bound by established rules and procedures, and traditional authority does not impress them, nor do slogans or catchwords. Only ideas that make sense to them are adopted; those that don't, aren't, no matter who thought of them. Remember, their aim is always maximum efficiency.
In their careers, Masterminds usually rise to positions of responsibility, for they work long and hard and are dedicated in their pursuit of goals, sparing neither their own time and effort nor that of their colleagues and employees. Problem-solving is highly stimulating to Masterminds, who love responding to tangled systems that require careful sorting out. Ordinarily, they verbalize the positive and avoid comments of a negative nature; they are more interested in moving an organization forward than dwelling on mistakes of the past.
Masterminds tend to be much more definite and self-confident than other Rationals, having usually developed a very strong will. Decisions come easily to them; in fact, they can hardly rest until they have things settled and decided. But before they decide anything, they must do the research. Masterminds are highly theoretical, but they insist on looking at all available data before they embrace an idea, and they are suspicious of any statement that is based on shoddy research, or that is not checked against reality.
Alan Greenspan, Ben Bernanke, Dwight D. Eisenhower, General Ulysses S. Grant, Frideriche Nietsche, Niels Bohr, Peter the Great, Stephen Hawking, John Maynard Keynes, Lise Meitner", Ayn Rand and Sir Isaac Newton are examples of Rational Masterminds.
Given the work I do and my albeit limited degree of self-awareness, it seems to fit quite well (if you know me IRL and have a different opinion, let me know).
But why the difference between my writing's ESTP profile and my "normal" INTJ? That will take some looking into, but my guess is that I don't feel a need to juice things up in day-to-day life, but can be very enthusiastic when writing about something because I know I won't be there to convey my thoughts in person. That's just a guess, but it's an interesting difference nonetheless.
If you try this, let me know if you come up with different profiles as well.
