Aaron Couture:  

y are more comfortable working alone than with other people, and are not usually as sociable as others, although they are prepared to take the lead if nobody else is up to the task, or they see a major weakness in the current leadership. They tend to be very pragmatic and logical individuals, often with an individualistic bent and a low tolerance for spin or rampant emotionalism. They are also commonly not susceptible to catchphrases and commonly do not recognize authority based on tradition, rank or title. Hallmark features of the INTJ personality type include independence of thought, strong individualism and creativity. Persons with this personality type work best given large amounts of autonomy and creative freedom. They harbour an innate desire to express themselves; that is to be creative by conceptualizing their own intellectual designs. Analyzing and formulating complex theories are among their greatest strengths.".
