There are roughly 222 million Americans old enough to have gone to Harvard. Of these, only 279,000 have actually attended Harvard. If we crudely assume that Harvard is the pinnacle of credentials, attending Harvard puts you at the top one in 796 level achievement (normalized Z score = +3).
Meanwhile of America’s 76 million baby boomers (alive or dead), only four grew up to be President of the United States (so far). If we crudely assume being President is the pinnacle of power, the Presidency puts you at the top one in 19 million level. The median U.S. president would therefore be at the one in 38 million level in power (normalized Z = +5.47).
Of the five living U.S. President, two have attended Harvard (Bush & Obama), so an achievement that is +3 Z in the general population, is only +0.27 Z among Presidents. This implies the average U.S. President is +2.73 Z in education (3 – 0.27). Considering the average U.S. president has an IQ of about 130 (+ 2 Z), this implies education is more important for achieving power than IQ (as Lion of the Blogosphere would agree).
This makes sense because education reflects not just IQ but social class and work ethic as well.
We can estimate that IQ correlates 0.37 with power (2/5.47) while education correlates 0.5 (2.73/5.47).
Pumpkin Person 
Someone once attended a Harvard graduation and asked 23 new grads why summers are hot and winters are cold. Only one gave the correct answer.
Any non-brainwashed person with a three-digit IQ is smarter than the entire Harvard faculty put together. Harvard has not selected for intelligence in a very long time.
Sample questions that no Harvard professor could answer correctly: Why does Roxbury have a murder rate several times higher than Cambridge? Is Caitlyn Jenner a woman? If my aboriginal culture says that 2+2=5, does that make it true?
“Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity” -George Orwell in “1984”
“Sample questions that no Harvard professor could answer correctly: Why does Roxbury have a murder rate several times higher than Cambridge?”
I don’t know where Roxbury is so I can’t answer that.
“Is Caitlyn Jenner a woman?”
Yes, she is, hence the need for differentiating between the terms “woman” (which refers to a gender identity, a feature of oneself which is entirely self-proclaimed and cannot be verified externally through objective methods) and “female” (which refers to a person’s sex, which is indeed an objectively observable trait). The difference between gender and sex tends to be conflated in the mind of progressive-leaning people, thanks to the tireless work of a few extreme transgender activists who apparently don’t realize that they couldn’t be transgender if gender and sex were indistinguishable. Also, if you are going to bother with blatant transphobia, then you should have at least taken the effort to use their old name.
“If my aboriginal culture says that 2+2=5, does that make it true?”
That’s ultimately a matter of semiotics. Of course if their culture associated symbols with numerals and operations in such a way that the statement “2 + 2 = 5” is true, then yes it does. However, no culture can make true the statement I understand by “2 + 2 = 5”, and whoever says otherwise is just being ridiculous for the sake of it.
I like this guy. Kinda interesting might be useful.
A Harvard professor would give such answers, plus a tragic-dirt explanation that so many black people in Roxbury kill each other and so few achieve the 1000 SAT score they need to get into Harvard, all because we racist white people make them live in bad places (Roxbury is a half-hour subway ride from Harvard) and go to bad schools.
