Are Big Breasted Women More Intelligent?

The stereotype has been perpetuated that big breasted women are less intelligent than their small breasted counterparts. It may be time to rethink this idea.

Are big breasted people less intelligent than their small breasted counterparts? Does breast size correlate with intelligence? Sometimes old stereotypes die hard. The idea perpetuated down through the ages is that big breasted women are less intelligent. This image has been reinforced in literature, in comic strips, and on television where the air headed woman is portrayed with overly processed blond hair and large breasts prominently displayed in an eye catching push up bra.

In contrast, the smart woman is generally depicted as being dark haired and small breasted, with thick rimmed glasses and a rather nondescript look. It may be time to rethink this outdated notion..

According to a study carried out by a Chicago sociologist in 2003, women with big breasts had ten point higher I.Q’s. on average than their less well endowed counterparts. This sociologist conducting the study, who admitted to being a 32A in breast size, looked at 1200 women of various breast sizes. She divided the women into five categories based on their breast measurements. These included extra-large, large, medium, small, and extra-small breast sizes.

The women were then given an I.Q. test to objectively measure their intelligence levels To the researcher’s surprise, women in the extra-large and large categories scored an average of ten points higher than women in the groups with the smallest breast sizes. Even women with medium sized breasts beat out the small breasted women by several I.Q. points.

While no one is sure why this correlation between breast size and intelligence may exist, it may have something to do with sex hormone levels which play a role in determining a woman’s breast size. There’s also the possibility there may be some natural selection taking place here.

If it’s true that men actually prefer women with larger breast sizes, the intelligent men may be selectively choosing larger breasted women as their reproductive partners. The resulting offspring would have a high likelihood of inheriting the genes for larger breast size from the woman along with the male’s genes for higher intelligence.

It’s interesting to note that women in the United States have the largest breast size in the world with an average bra cup size of C. Does this mean we have the smartest women in the world? There’s also the issue of breast enhancement. Unfortunately, it doesn’t seem likely that a woman can increase her intelligence by getting large breast implants, though no study has been done to confirm or refute this.

So, the next time you’re tempted to call that gal with the big breasts jutting out of her Victoria Secret’s push bra a bimbo, think again. She may actually be a rocket scientist.

    As someone in the image field who has read other sociological articles about breasts, thanks. The evolutionary explanation is quite original and makes sense. It would be nice to see the actual study, which for example would answer the question of whether the researcher took into account body weight and the intelligence-linked trait that is height. The one comment worth making here is that intelligent women probably tend to be more modest in public dress than less intelligent women, leading observers to think that they’re smaller on top than they are.

    that is why women wear a bra

  3. kg Says:

    No surprise that American women are the world’s most well-endowed–they’re also the world’s fattest. But then, intellectual activity is fairly sedentary…

  4. ictguy Says:

    Who cares how intelligent big busted women are. They have big breasts.

    i love the feel of a good sized breast..its a good thing i dont have themmm..or else i never would have gotten married…

  6. subzero Says:

    wow.. my girlfriend hav large breast… and she is smart … hmm.. i this thing must hav been true O.o

  7. Tommy Says:

    My wife is incredibly smart. She also is very well endowed. Her mind is what attracted me to her, Seriously. It’s a biological imperative that some men have, that make large breasted women attractive. I want my children to be as smart if not smarter than I am.

  8. Dropyourguns Says:

    My Wife is as smart as a whip she is also a 38E. I was attracted to her wit and warmth………. the fact that she is a 38E is a Bonus for me.

  9. lovelyhoney Says:

    beauty is in ones mind and sex only brain does through inherited genes define beauty and brains do not go together however if beauty and brains were one do find we will all call them

  10. Flabbergasted Says:

    Interesting! Until now I had my very own theory that “well-breasted” teenager girls were more at risk to be diverted from the academic path, as soon as they had bloomed, because of all the male attention (at school by wannabe 12-year old fathers, on the street by wannabe pedophiles..) which could end up perverting their innocent (and until then, school-focussed) mind!

  11. womanwithanIQ Says:

    What utter rubbish!
    What do you mean ‘admitted to being 32A’ ? Your use of admitted makes it sound like a confession. How fortunate to have pert, young looking breasts rather than the saggy bags of fat that you seem to admire. As for USA breast sizes, C cup is average in most of the western world so nothing to boast about there. Are American woman more intelligent? If this article is an example, ofviously not.
    Oh, I am 36B and a member of Mensa … I was 36A when I was tested though.

  12. lane Says:

    I have blonde hair, am thin, and wear a 32DD sized bra, and i’m all natural. People think i’m dumb but my IQ is 140. I’m glad this study was published because people assume i’m just a bimbo!

  13. A. E. Says:

    So, Iane, … how you doin? is there a boyfriend in the picture?


    I think the part about U. S. American women having larger breast on average might be true; keep in mind they are also have more weight problems in average, so it’s only natural. I’m actually under the impression that fit women from Eastern Europe have bigger cups than those from the rest of the world, while Japanese are about the opposite.
    Another thing, the article quotes a “sociology study from Chicago, done in 2002″. Can we know the name of the institution and author?

    Smart girls get implant! Solved!

    Oh my god you guys so smat it almost hurts! You guys must be phd in quantum mechanics… But who know me. My girlfriend have boobs. HAHAHAHAHAHA

  16. Some woman. Says:

    Does that mean that men with bigger penises are more intelligent than their not-so-well-endowed-counterparts?

    I\\\’d like to see an experiment done on that, if you please.

  17. brneyez Says:

    Hey I’m a 34a is this suppose to be a bad thing?

  18. seanlam Says:

    I beg to differ to those view that most of the guys likes lady with bigger size of breast.

    Personally, I don’t mind either my future partner are endowed with big or small or medium…or whatever it is, as long as its naturally one. Yes, I’m a dude.

    So, to me I don’t really care about it.

    Well ,this is mine 2cents opinion…lol No offense.

  19. nonanon Says:

    where is the button for “do no like” should it not be right next to the “i like this” button?

  20. Susan Says:

    Does no one realize the “Study” was fake? Try finding it. the study is attributed it to Yvonne Rossdale.. and she’s not a real person.

  21. Guest Says:

    COOL now we are going to measure intelligence by the breast size…My intelligence is 30 GG :-D

  22. big man Says:

    what about male(penis)?

  23. Eric Says:

    Intelligent men can see past those things.

  24. JM Says:

    IQ isn\’t a real marker of genuine intelligence anyway …. and, incidentally, black women don\’t have the largest breasts by any stretch of the imagination. So that argument falls down on both counts.

  25. Katey Lavacca Says:

    If you want large breasts get pregnant. If you don’t want to get pregnant do an implant. Its that simple! If you want a high IQ knock your brains out. The two don’t have anything in common. The study is hogwash!!! Rubbish. Simply rubbish!!!

  26. Alberta Franza-Gioberti Says:

    Who performed the study? A big nosed Beagle? The study is nonsense!

  27. Erwin Brady Says:

    I have a Master’s Degree. I saw women of different kinds of builds attending school there for four years. Their bodies were irrelevant to their studies.

    Plus, the Principal of the Elementary School just two doors down from my home has a va-va-va-voom figure. I hear you have to have a Doctor’s Degree to be a School Principal. Her looks are irrelevant to her career.

    I might be able to keep recalling similar women, but I think you get my point.

    Poor flat chested women. No boobs or brains!

  31. Tits McGee Says:

    wow some people took this way too seriously and are so sensitive.
    To the self declared intelligent black woman, it may be offensive that your race is technically dumber, but that doesn’t make it less true.
    “The Worldwide Pattern of IQ Scores. East Asians average higher on IQ tests than Whites, both in the U. S. and in Asia, even though IQ tests were developed for use in the Euro-American culture. Around the world, the average IQ for East Asians centers around 106; for Whites, about 100; and for Blacks about 85 in the U.S. and 70 in sub-Saharan Africa. ”

    I have no idea if my chest size(40H) and my IQ (137) have anything in common.. I know I came from German heritage and my great grandmother was extremely large chested and also extremely smart and outspoken… especially for a woman born in her era. I think THOSE genetics have more to do with my intelligence then the boobs I obviously inherited from her.

  32. crazybrettdarjit Says:

    I feel that the larger a woman’s breasts, the more likely she is able to give a very intelligent blowjob to an unsuspecting counterpart. To measure the intelligence of a blowjob, one must be able to quiz the blowjob giver’s lips sporadically throughout the entire blowjob process. With such questions as, “What is Thomas Alva Edison’s middle name?” and “What is that?”, one can learn a great deal of the intelligence of a large breasted woman who is favorable to giving blowjobs on 34th and Keeler.

  33. Franz deLewis Says:

    “The women were then given an I.Q. test to objectively measure their intelligence levels”

    “I.Q. test to objectively measure their intelligence”

    “…I.Q. … objectively”

  35. Fred Says:

    I would not have expected any correlation. IMO, I think the ‘women with large breasts are dumber’ stereotype was invented to defend women’s egos, just like the saying “it’s what you do with ‘it’ that matters” was invented to defend the male ego. They might both be outright, sugar-coated lies, but that doesn’t stop them from being perpetuated since it’s what everyone wants to hear.

  36. Daniel Says:

    The assumption presented in this article is FAKE. Check out this page were they explain this HOAX about more intelligent big breasted women

  37. HandsomeLustyOlderBlackLad Says:

    VERY INTERESTING,this new assertion that big breasted women are actually MORE INTELLIGENT than their smaller-spudded sisters,but frankly,I’m one lad who sees a chesty lass and doesn’t think of her IQ,just her bra size and cup.(34C-42D,girls!!!)

  38. September Sue Says:

    I have an IQ of 165 and my bra size is a 38H. So, think about that guys!!

  39. ricky Says:

    honestly arguing about breast? Next why don\’t we all just argue about balls and mattresses!

  40. LustyBlackLaddieBrett1953 Says:

    September Sue,if you”re into life-size Brett dolls-in my case,a
    boyishly handsome,57-year-old-58 July 6-black Canadian laddie…HERE I AM!!!

  41. LustyBlackLaddieBrett1953 Says:

    And September Sue,your IQ is 5-18 points HIGHER THAN MINE!!!

  42. violet Says:

    Um, first, it is very doubtful that the chick who posted she has 140 score on her IQ is telling the truth, just sayin’. I am astounded that someone would take the time to conduct this study. I think the author of the article is a fucking douche bag and agree with the above comment that “admitting” to having a 32 A is bogus. Here am admitting to you all that I am a 32 A. I would love it if I were a teense bigger, as I think it is important to be proportionate, as I think this looks nice. But I think women with big boobs and no ass are way less attractive than the opposite, pear-shaped woman. I like being small breasted. I think if I had double DDs or even if I were a C, I would have gotten more attention from creepier men, particularly during high school. No thanks.

    As for intelligence, it is important to note that IQ is not the only way to test intelligence. Many people do not particularly believe in this mode of noting how smart someone is. Furthermore, anxiety and low self esteem play a big part of scoring well on an IQ test. And if one understands that their small boob size has everything to do with why they are taking the test, and if the tone of the experiment is obviously not flat-chester friendly, well, man, I know I would not feel my most secure.

    I do believe the sterotype that flat chested, small boob-ed chicks are classier remains. I do not know that it has much to do with IQ, but I think it has everything to do with social Darwinism. Which women are rich men choosing? Who is just more sensual, and not just “hot.” I do not like that small breasted and large breasted women need to be pitted against each other; it is sad and denotes the state of feminism or lack thereof in both our country as well as in myself. However, I do not think progress is going to happen any time soon. And for this reason, man, I am sticking with the flat chested chicks. BIg boobed girls, I think now it is high time for you to “admit to” making farting sounds with your boobs while you “do it.”

  43. someone Says:

    That study is attributed to the non-existent Dr Yvonne Rossdale from the Weekly World News seen here (copy and paste the URL):

    It is just a few pages after the story about how a “cat virus turns women into sex kittens.”

    End of discussion.

  44. Mickie Says:

    Russia has the largest average breast size. Sorry USA!

  45. Aquablue72 Says:

    This study dose not prove anything, look at asians they have small breasts but theyre smarter than americans with bigger breasts.

  46. Erra Says:

    That article is from a fake magazine…
    I remember my dad buying those for laughs.

  47. Maria Says:

    I want to know when they’re doing the study that shows men with ten inch penises are smarter than their wee willie counterparts. Oh wait, most scientists are men…no wonder we get BS studies like this.

  48. Emmett Says:

    There was no such study. It’s too bad that today’s “journalists” no longer do fact-checking before broadcasting fake studies from the Weekly World News.
