What Everyone Needs to Know About IQ (Defines IQ, describes the different
measurement scales that are subsumed under the rubric "IQ", and
discusses what this means for any IQ scores you may have gotten over the
past 30-50 years.)
Deviation IQ's vs. Ratio IQs (Explains the difference between the "old"
ratio IQs, designed to measure children's intellects, and the
"new" deviation IQs designed for adults.)
Log-normal
distribution Discusses the fitting of high-range IQ data with
a log-normal distribution (modified bell curve) rather than a
purely-Gaussian bell curve.

Boosters" by Ray Sahelian, M. D. (Amazon)
This well-researched $11.96 book reviews over-the-counter nutrients
that seem to be able to, possibly, temporarily boost IQ, and
to temporarily modify biochemical regulators within the
brain. Dr. Sahelian has tested everything he describes. (He urges
moderation.)

III. Adult Intelligence
Is IQ irrelevant once it reaches 120?
(Discusses the surprising fact that worldly
success, including academic success, is largely independent of
IQ once the IQ exceeds about 120. Note: This claim
is strongly disputed by insiders insofar as it applies
to leading U. S. mathematicians and physicists. Deviation IQs
of no less than 150 and probably primarily 160+ are claimed to
be necessary for cutting-edge work in these esoteric and competitive
domains.)
The Empty Promise (Grady Towers' discussion of the fact
that even academic success seems to be independent of IQ above
IQ 120 - see above.)

Who Are They? - The
Megans are the
~25 people who have qualified at the one-in-a-million level of
IQ. Others whose SAT scores betoken the highest levels of intelligence
are Bill Gates*, Paul Allen*, and perhaps,
Steve Ballmer, with Microsoft Corporation. Warren Buffett, the
Sage of Omaha, and George Soros of hedge fund fame are among
other multibillionaires said to be included in this stratospheric
league.
*- Bill Gates is said to have scored 1590
on the pre-1995 SAT, while Paul Allen is alleged to have gotten
a perfect 1600.
