Crystallized and Fluid Intelligence
The Kaufman Adolescent and Adult Intelligence Test (KAIT) introduces the concepts of fluid,
crystallized, and composite intelligence. In brief, crystallized intelligence is the knowledge that a
person has accumulated throughout their lifespan. This means that a person who goes to college,
reads lots of books, etc. is probably going to have more crystallized intelligence than a person who
spends all their time staring at a wall. Fluid intelligence, by contrast, is the ability to solve
problems without the help of a preexisting knowledge base. A person who spends all their time
staring at a wall can still have more fluid intelligence than a person with a college degree.
1,297 people of various ages and sexes took the KAIT. INs tended to do the best overall, followed
by ENs, then ISs, then ESs. 196 Intuition, however, was the real determinant of how well one scored
on this test—a finding that has oft been repeated in scientific literature. This likely hearkens back
to the tendency to define intelligence as "abstract reasoning skill."
One additional, intriguing finding was that the participants in the study (who ranged from teenagers
to octogenarians) tended to become more Judging as they aged. It would seem that people tend to
place more value on regular routines as they grow older. The E/I, S/N, and T/F functions were not
affected by aging.
INTJ Geniuses
One of the best ways to differentiate between type and intelligence is to study extremely intelligent
people of a particular type. Oftentimes, people mistakenly point to manifestations of type as being
due to "genius" when they are actually very ordinary characteristics of type. For example, a
researcher may observe an INTJ genius reading the encyclopedia for fun and attribute this behavior
to high intelligence. In reality, INTJs of all intelligence levels have a thirst for knowledge, though
in our modern times the encyclopedia has been replaced by Wikipedia. The genius' intelligence
does allow them to imbibe knowledge more quickly and retain it more easily than for ordinary
INTJs, but the unending desire for information comes from type, not genius. Indeed, geniuses of
other types may have no interest whatsoever in reading or science.
As we shall see, there isn't much difference between the behaviors of geniuses and those of average
members of the type. INTJ geniuses are not so much different as better. Indeed, above-average
INTJs may find that some of the problems which INTJ geniuses struggle with are the same ones
that they themselves struggle with, only magnified into dramatic proportions. By studying these
outliers, we can learn quite a bit about the problems faced by average INTJs.
In this section, we’ll review the traits of two individuals with genius IQs whom I believe to be
INTJs. At the time their cases were reviewed, neither had achieved fame or made a significant
contribution to science. Nevertheless, their stories are interesting because they illustrate the
manifestations of high intelligence as expressed through the INTJ personality.
Note that an IQ of 100 +/- 15, is considered average. An IQ over 180 is found in something like 1-3
people in a million. Both children (C and L) were first described by Leta Hollingworth in 1942.
