The Portrait of the Mastermind (INTJ)

Here is an interesting personality assessment test; the Myers-Briggs personality assessment,
very popular in some circles.  I don’t know how useful it really is, but
I do find that it describes my personality fairly well, and it is quick and fun to
take.  Recommended.

I am an INTJ – the Mastermind.  Here is what the site has to say about
me:

The Portrait of the Mastermind (iNTj)

Of the four aspects of strategic analysis and definition it is the contingency planning
or entailment organizing role that reaches the highest development in Masterminds.
Entailing or contingency planning is not an informative activity, rather it is a directive
one in which the planner tells others what to do and in what order to do it. As the
organizing capabilities the Masterminds increase so does their inclination to take
charge of whatever is going on.

It is in their abilities that Masterminds differ from the other Rationals, while in
most of their attitudes they are just like the others. However there is one attitude
that sets them apart from other Rationals: they tend to be much more self-confident
than the rest, having, for obscure reasons, developed a very strong will. They are
rather rare, comprising no more than, say, one percent of the population. Being very
judicious, decisions come naturally to them; indeed, they can hardly rest until they
have things settled, decided, and set. They are the people who are able to formulate
coherent and comprehensive contingency plans, hence contingency organizers or "entailers."

Masterminds will adopt ideas only if they are useful, which is to say if they work
efficiently toward accomplishing the Mastermind's well-defined goals. Natural leaders,
Masterminds are not at all eager to take command of projects or groups, preferring
to stay in the background until others demonstrate their inability to lead. Once in
charge, however, Masterminds are the supreme pragmatists, seeing reality as a crucible
for refining their strategies for goal-directed action. In a sense, Masterminds approach
reality as they would a giant chess board, always seeking strategies that have a high
payoff, and always devising contingency plans in case of error or adversity. To the
Mastermind, organizational structure and operational procedures are never arbitrary,
never set in concrete, but are quite malleable and can be changed, improved, streamlined.
In their drive for efficient action, Masterminds are the most open-minded of all the
types. No idea is too far-fetched to be entertained-if it is useful. Masterminds are
natural brainstormers, always open to new concepts and, in fact, aggressively seeking
them. They are also alert to the consequences of applying new ideas or positions.
Theories which cannot be made to work are quickly discarded by the Masterminds. On
the other hand, Masterminds can be quite ruthless in implementing effective ideas,
seldom counting personal cost in terms of time and energy.
