in Facts

An intelligence quotient, or IQ, is a score derived from one of several standardized tests designed to assess intelligence. The abbreviation “IQ” comes from the German term Intelligenz-Quotient, originally coined by psychologist William Stern.

IQ scores are used as predictors of educational achievement, special needs, job performance and income.

Good day! The scale usually associated w/IQ scores runs from 0 to 200, and 100 is deemed average. Another way to regard it is as a classic bell-shaped curve, w/half the testees in the 0-99 half and the second in the 100-200 half, w/all shades between.

Do you have an estimate IQ on Henry viii?

3. Stephen — September 3, 2013 at 7:49 am

Hi Carol! Unfortunately I don’t :(

Well, it’s obvious that he wasn’t smart enough to keep his wives…. More seriously, it’s my understanding that J W von Goethe had the highest estimated IQ, at 200. One cannot go past this point on the traditional scale, as it is the end. One could move the goal posts, of course, but that affects the same change at the lower end, to the same equilibrium as before, thus nothing is gained. So the estimate of da Vinci’s at 220 isn’t possible, currently.

It was never meant to measure or indicate one’s prowess in politics or entertainment, so how war-mongers such as Obama, the Clintons, and Bush 43 made it here are murky, at best; ditto for Madonna, Holliday, and Schwarzenegger.

How is it possible to estimate the IQ of people such as Leonardo da Vinci when the IQ test wasn’t around prior to the early 1900′s? What measures are used to compare?

Responding to the question about Henry VIII, I would assume he was pretty intelligent since he composed music, wrote poetry and prose, and was an accomplished athlete. He successfully ran a country, created the foundation of the Anglican Church, and in my opinion, created the society in which the Renaissance could take root in England. Without Henry VIII, we would have no Elizabeth or James (and no King James Version of the Bible). I’d definitely put him at well above average.

Are the IQs listed above for modern individuals based on administered tests or are they estimates?

8. Zombiegirl — December 22, 2013 at 1:23 am

My IQ is 113

9. Christoper — January 23, 2014 at 4:59 pm

Barack Obama’s IQ is more like 116 as Harvard test results were done. His highest possible, would be 119 on a very good day?!

If Madonna’s IQ is 140, my waist is 28, my biceps are 14 inches and other parts of me are close…….She is a damn Moron and the World knows it……

11. Jerry — March 3, 2014 at 8:14 pm

My IQ was 155 at age 9. I believe it has dropped with time.

12. Gregory — March 5, 2014 at 6:40 pm

There is absolutely NO way Bush’s IQ is even close to Obama. And 220 for Da Vinci? I had heard the highest ever was about 201 which was a woman

13. Elizabeth — March 13, 2014 at 10:10 pm

DaVinci..he was far more brilliant and creative that anyone who had existed before, or that came after him.

And i find it silly that people have to put down Bush because they do not like him. Not an intelligent comment, Gregory.

I am assuming that those that were around before the invention of the i.q. tests are estimates.
Intelligence has nothing to do with morality either, so why put down Obama, Bush, or the Clintons. They can be intelligent, but also not ethical.

And why can’t movie stars be intelligent? Why put down Madonna, Arnie, or Holliday?
Sometimes the comments on here do not reflect all that much intellect, but emotional “reasoning”.
