They often have unique opinions that they arrive at through long thought.
Approach to Problem Solving—With Legos!
The TJ part of INTJ adds decisiveness and leadership abilities to this type's repertoire of behaviors.
Kroeger & Thuesen (1988) did a fascinating experiment on the problem solving techniques of each
type. They took a group of engineers and divided them into four groups of interest: SPs, SJs, TJs,
and NTPs. The teams were tasked with problem of assembling a copy of a Lego Man model that
been provided for reference. To challenge was to assemble the copy in the shortest amount of time,
with a one hour deadline.
Now, the interesting thing about this contest is that though the goal was to assemble the Lego Man
as fast as possible, there was no limit on planning time save of course for the one hour deadline. So
a team could spend 45 minutes planning and 15 minutes assembling, and still beat a team that spent
20 minutes planning and 16 minutes assembling.
The experiment turned up some very interesting results:
SP 4 minutes planning 30 minutes assembling 1 error 34 minutes total
SJ 17 minutes planning 15 minutes assembling 0 errors 32 minutes total
NTP 31 minutes planning 9 minutes assembling 1 error 40 minutes total
TJ 26 minutes planning 4 minutes assembling 0 errors 30 minutes total
The TJs won the contest hands down; from planning to execution, they were the most efficient of all
groups. (They also managed to alienate one of their members, something that none of the other
groups did.) Like all the TJs, the INTJs are a single minded bunch focused on results.
Compare this approach with that taken by the SPs, who essentially "brute forced" the solution
through rapid experimentation; the NTPs, who explored the problem at length before trying to solve
it; and the SJs, who spent equal planning and assembling.
Now here's an interesting question—given that the TJ approach was the most efficient in every way,
why haven't the forces of evolution converged to create a version of humanity that is purely TJ?
The answer is that each of the different problem solving strategies used by the groups is useful in a
particular circumstance. For instance, the SP strategy of not planning works well under
unpredictable situations where plans would be rendered obsolete before they could be finished. Or,
the NTP preference works well when there is time to explore a problem at length, potentially
producing a more considered result than a faster but less considered method would. But perhaps the
fact that TJs are most often placed in leadership positions reflects the fact that this preference is
most efficient overall at completing plannable tasks that have clear objectives and a deadline. 1
INTJ Politics
Did you know that type and politics are related? Sensing is correlated with a more conservative
political stance, while Intuition is correlated with a more liberal political stance. 2 In addition,
Intuitives reported having higher political interest than Sensors. 3
1 As we'll see in the section of intelligence tests, it is very important to set the parameters of a test in such a way that
it proves your own type is the most intelligent.
