INTJ's are pragmatic theoreticians who like to develop plans, designs, or theories that work in the real world—in fact they are often more interested in designing a writing project than in writing it. They often incorporate design elements, such as flow charts, diagrams, and schematic drawings in writing. As a result, their writing is the most clearly and consistently organized of all MBTI types. For INTJ's, the idea is the most important part of the message—they don’t need to "entertain" the audience.
Below are some of the advantages and challenges INTJ's face when writing:
Like to complete writing projects quickly—never miss deadlines.
Original thinkers with neat, orderly minds.
Often have good ideas which they present in a clear, organized manner.
May be too locked into the plan.
Concern with speed may lead to skimpy research.
Need more spontaneity.
Need more audience focus—soften harsh statements or qualify assertions.
