He has not released that information. From the information available:
- The average IQ for a college graduate with a bachelor's degree in the U.S. is 115.
Obama graduated Magna Cum Laude from Harvard Law School.
- Obama's IQ has been estimated anywhere from 110-165. He is a graduate of Columbia University and Harvard Law School, where he served as editor, and later as president of the Harvard Law Review; which is an extremely prestigious position. Obama also taught at the University of Chicago for over 10 years, a top-ranked university in the United States. However, these achievement-based estimates fail to account for the possibility that Obama was a beneficiary of affirmative action, which based on collegiate averages would lower his estimated IQ to the 115-120 range.
- Obama attended an elite private school in Honolulu as a scholarship student. Since all of the graduates from that school at that time took collegiate aptitude tests and he was not a National Merit Scholar, Semifinalist, or Outstanding Participant, his maximum possible score on the SAT was 1230, which is the 96.9 percentile. That would translate to a maximum possible IQ of 129. It should be noted, however, that one of the requirements for the National Merit Scholarship is taking the Preliminary SAT test. If Obama did not take the PSAT, he could very well have scored above 1230 on the SAT without being a National Merit Scholar.
- Note: To many professionals in the 'IQ' field , this is all utterly absurd. I have no idea what Barack Obama's IQ is, but nobody with even a rudimentary understanding of what IQ means and how it is determined would suggest that any of the estimations methods (school grades and positions held at college) described in the answer have any validity whatsoever.
- Affirmative Action helps minority students get into a prestigious school, not help them achieve when they get there. It's hard to believe that anyone who graduated second in his class out of the elite students could possibly have an IQ of 129 or less. Though the "Intelligence Quotient," or IQ is not the best determining factor for such an epistomological question one would need a higher IQ to understand the logic that goes along with American law. These answers are all speculation so the answer is undetermined and based on subjectivity. In order to become objective more research is necessary, especially on the basis of Harvard Law graduates. A study taking their mean IQ scores would be necessary. It couldn't even be combined with a study of the relation between SAT scores and IQ. Anyone could subjectively make up a number based on little true research and without warrant claim his IQ be 129.
