U.S. Presidential IQ Scores
Using regression to calculate Trump’s IQ.
U.S. News and World Report published
this list of presidential IQs from highest to
lowest.
John Quincy Adams is the highest with
168.75. Ulysses S. Grant is the lowest
with 120.
Average IQ is 100 with a standard
deviation of 15. Average presidential IQ
is 135.
Here's Why Donald Trump Doesn't Want
Anyone To Know His Grades Or SAT Scores
“I’m talking about a man who declares himself brilliant, but directed me to threaten
his high school, his colleges and the College Board to never release his grades or
SAT scores,” Cohen told the House Oversight Committee.”

“Sorry losers and haters, but my I.Q. is one of the highest -and you all know it!
Please don't feel so stupid or insecure, it's not your fault,” Trump tweeted in 2013.

Trump’s IQ
An article appeared in 2017
claiming Trump’s IQ to be 156.
This was based on Wharton’s
freshmen SAT scores matching
that of 156 IQ. However Trump
transferred to Wharton as a junior,
and his SAT scores have been
unavailable. This post also
claimed Obama’s IQ was too low
to post (it’s 155.)

Trump’s speeches have
a 4th grade reading
level. If this data can be
correlated with matching
presidents’ IQ scores,
we can establish a
regression equation to
calculate Trump’s IQ.

Regression Equation from data is:
IQ = 2.69x + 116, x is Grade Level.
Trump = 2.69(4.6) + 116 = ???
Predictions range from 128.7 to 143.7, avg 132.5. However, the higher correlation
coefficients correspond to lower IQ values. (Highest r = 0.327 has 127.5 IQ.)
Are the predicted IQ values accurate?
The y-intercept of the regression equation was 116, meaning a 0 grade level is
spotted an IQ of 116. This is one standard deviation above the mean, but lower
than the lowest presidential IQ. However, a correlation coefficient of 0.327 is not
strong having a variance of 9%.
By GPA we calculated an IQ of 89. By Grade Level, it was 132. Average is 110.
However, the grade level regression doesn’t have high correlation factors. The
report card was proven to be a forgery. Which IQ seems most plausible?
156? 89? 132? 73? 110?
The etymology of name-calling--moron, idiot, imbecile.
Idiot, imbecile, and moron were, not so long ago, used in a psychological
classification system, and each one was assigned to a fairly specific range of
abilities.
Idiots. —Those so defective that the mental development never exceeds that or a
normal child of about two years.
Imbeciles. —Those whose development is higher than that of an idiot, but whose
intelligence does not exceed that of a normal child of about seven years.
Morons. —Those whose mental development is above that of an imbecile, but
does not exceed that of a normal child of about twelve years.
— Edmund Burke Huey, Backward and Feeble-Minded Children, 1912
