IQ Facts and IQ of Famous People

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.

    i have an iq of 146 and im 12 but i wanted to pass albert einstein

  • Philip Seltzer January 12, 2019, 3:34 am

    IQ tested as a child (nearly 60 years ago) at 155. Wish I had some common sense though, and psychological issues have mitigated the benefits of my intelligence. I think it was Thomas Edison who was supposed to have stated that genius is 1% inspiration and 99% perspiration. That may be overly skewed towards perspiration, but the point has validity.

  • Justin Toffoletti January 6, 2019, 9:20 pm

    IQ 129 at 13. I’d say that’s pretty decent

  • Oral Phillips January 4, 2019, 8:00 pm

    My IQ has on average been 178 and although well read, I otherwise am not that intelligent.

  • Jules December 19, 2018, 4:39 pm

    118 at age 59. That makes me only a bit below John F Kennedy but dumber than George Bush? Huh?
    All in good fun LOL!

  • Eduardo March 31, 2016, 3:23 pm

    All these vexatious people in the comments that say that their IQs are high is probably because they googled the answers to an inaccurate IQ test.

  • Tia April 8, 2015, 12:01 am

    OMG!I never knew Muhummad Ali’s IQ was 78! I heard some one say that Barack Obama had an IQ of 159 and he had a MENSA member ship….??? bruh … Anyway , this was super interesting thanks!!

  • Martin March 5, 2015, 9:24 am

    I always score in the 120s, but I’m not well spoken, though pretty good at logic….makes me think these tests are flawed

  • Dave March 2, 2015, 1:15 am

    I am curently 14 years of age and after several tests, I have the average result of 129, I am quite a bit more intellegent than my fellow peers. I just wanted to share my findings.

  • Tampuri Hakim January 19, 2015, 3:55 pm

    I have an I.Q of 130, and it motivates me work harder to maintain my intelligence.

  • Kay Lynn November 28, 2014, 10:49 pm

    I’m 11 and I have an IQ of 130. That is okay, I suppose, but I want to be higher than Sir Issac Newton (190).

  • MOTI November 28, 2014, 3:10 am

    my IQ is 187 at my 19 age!!!!!!!. congratulation!

  • Lukas November 10, 2014, 3:57 pm

    IQ measure favors those in the academics. When we were in school my brother had no interest in anything academic and his IQ score was low. However, he’s naturally clever with his hands; crafts, mechanical assembly, he could easily do it. Many adults with good IQ score cannot even fixed a simple DIY furniture.

  • leke November 8, 2014, 8:37 am

    A.Eintein once said “every body is a genius but if you judge a fish by its ability to climb a tree then it will spent its whole life thinking that it is stupid” so guys those of you whose IQ values are as low as mine shouldnt bother cuz IQ or QI is deffinitely not a true test for Intelligence.I belief that every thing is Relative.or what ever

  • Christina November 3, 2014, 10:07 pm

    Can you tell me how do you know about the IQ of these famous people,such as Da Vinci? I do not think the IQ tests existed at that time.


  • Knq34jr October 16, 2014, 1:58 pm

    Spencer Reid criminal minds 187

  • Carol A. mcGuire October 12, 2014, 4:34 am

    Could we please get back to Henry VIII? I have wanted to know this for years! If anyone knows someone who understands how to calculate this would you please ask them to.I have searched and searched the internet to no avail. I did read, fairly recently, that he had an amazing memory, but was incapable of independent thought; which does make sense to me. Please, I’m asking for help here.

  • Iqra October 11, 2014, 3:25 am

    There is nothing in reality about IQ test ,i am only believe on my ALLAH

  • Finn506 October 7, 2014, 2:31 pm

    I read that Alfred Einstein was asked “How does it feel to be the smartest man alive?” and he replied, “I don’t know, you’ll have to ask Tesla.” Any idea what Tesla’s IQ would have been?

  • Joseph E Fasciani September 27, 2014, 11:33 am

    Friends, please bear in mind that ALL such tests can only accurately reflect the inherent prejudices or biases of their designers.

    They do not, they CANNOT measure ‘intelligence’ as such, but rather how the test-taker is able to relate to what the culture of that particular test believes are favourable, positive outcomes or directions.

    An IQ test test devised by Australian natives would be failed by anyone else, as we were not raised in that culture. Einstein and Goethe would be at as much of a loss as any of us would; so tell me, what was measured and what did we fall short of in that case?

  • woman September 18, 2014, 4:40 am

    For mine is 121 . What I could be with this iq idealistically

  • Kyleia August 8, 2014, 1:14 am
