Portrait of the Rational Mastermind (INTJ)
Masterminds are rare, comprising no more than one to two 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. ...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. ...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.

Yep, that's me. "Rational Mastermind" makes me chuckle. The Brain from Pinky and the Brain pops into my head immediately. "...the same thing we do every night Pinky, try to take over the world!"
