Myers-Briggs correlation with IQ



I was searching for information on the correlation of MBTI
types/subsypes to IQ. I came accross the following page:

Unfortunately there is no reference or e-mail address - but overall the
blog seems very competent.
----------------------
* Other personality traits being the same, an iNtuitive person
(one who grasps patterns and seeks possibilities) is 27 times more
likely to have a high IQ than a Sensing person (one who focuses on
sensory details and the here-and-now).

* Again, other traits being the same, an Introverted person is
8 times more likely to have a high IQ than one who is Extraverted; a
Thinking (logic-oriented) person is 2.5 times more likely to have a
high IQ than a Feeling (people-oriented) person; and a Judging person
(one who seeks closure) is about twice as likely to have a high IQ than
a Perceiving person (one who likes to keep his options open).

* Moreover, if you encounter an INTJ (Introverted, iNtuitive,
Thinking, Judging), there is a 37% probability that his IQ places him
in the top 2 percent of the population. The probability is 20% for an
INTP, 15% for an INFJ, and 8% for an INFP. These four types account for
66% of the high-IQ population but only 6% of the total population.

Does anybody have references to correlations between IQ and MBTI
types/subtypes?
