According to a paper by J. Philippe Rushton, the average size for erect
penises is:
Group --------Length -------Diameter
Orientals -----4 - 5.5" -------1.25"
Caucasians ---5.5 - 6" -----1.3 - 1.6"
Blacks -------6.25 - 8" --------2"
Okay, it has taken me a couple of days to find the time to go the library and pull this paper to read it thoroughly. Before the results, a couple of notes.
Rushton is a rather controversial publisher who has a strong theory about racial evolution in which he asserts that along a number of parameters the three races he recognizes (Black, Caucasian, Oriental (his terms)) consistly line up in that order.
Here is some of the press notices for his book length elaboration of the above article, which he quotes himself on its jacket:
(An) incendiary thesis....that separate races of human beings evolved different reproductive strategies to cope with different environments and that these strategies led to physical differences in brain size and hence in intelligence. Human beings who evolved in the warm but highly unpredictable environment of Africa adopted a strategy of high
reproduction, while human beings who migrated to the hostile cold of Europe and northern Asia took to producing fewer children but nurturing them more carefully.
---Malcolm W. Browne, New York Times Book Review
Rushton is a serious scholar who has assembled serious data. Consider just one example: brain size. The empirical reality, verified by numerous modern studies, including several based on magnetic resonance imaging, is that a significant and substantial relationship does exist between brain size and measured intelligence after body size is taken into account and that the races do have different distributions of brain size.
---Charles Murray, Afterword to The Bell Curve
Describes hundreds of studies worldwide that show a consistent pattern of human racial differences in such characteristics as intelligence, brain size, genital size, strength of sex drive, reproductive potency, industriousness,
sociability, and rule following. On each of these variables, the groups are aligned in the order: Orientals, Caucasians, Blacks.
---Mark Snyderman, National Review
Rushtons Race, Evolution, and Behavior...is an attempt to understand [race] differences in terms of life-history evolution....Perhaps there ultimately will be some serious contribution from the traditional smoke-and-mirrors social science treatment of IQ, but for now Rushtons framework is essentially the only game in town.
---Henry Harpending, Evolutionary Anthropology
.
This brilliant book is the most impressive theory-based study...of the psychological and behavioral differences between the major racial groups that I have encountered in the world literature on this subject.
---Arthur R. Jensen, University of California, Berkeley
That is a pretty accurate picture of his book, and it is also gives you a good sense of who his supporters are. For those who don't know these quotes come from the who's who of controversial race scholars/academic outsiders.
This article is easily available in abridged form on the internet, but if you google it you will get something like ten times the number of hits for articles which attack it for everything from data manipulation to poor math skills. It is an enduring subject of controversy.
Now the result:
Rushton actually makes only glancing reference to penis size in his article, or for that matter in the book length expansion of it. He absolutely
does postulate that penis size, like everything else, lines up with Blacks as largest, Whites in the middle, Orientals the smallest. (His terminology.) However,
I can find nothing like the chart that superlarge reproduces anywhere in the journal article or in the book. (IF you read superlarge's post he doesn't actually say this chart is from this article, by the way, but since it is sourced I took it for granted.) The only thing in the book that approaches measurements for the races is a prose note that condoms have a width of 49mm (sic) in Asia, 52mm in North America and Europe, and 53mm in Africa, which is not sourced.
In other words, Rushton suggests that the only difference in Blacks and Caucasions is that they sell condoms with one millimeter, though surely he meant centimeter, of difference in their girth. (He notes a larger difference, still less than a half inch, between those and orientals.)
Please note, before anyone writes and accuses me of smearing superlarge, that I am not suggesting he mislead us on purpose. I have my own extensive experience with finding citations in secondary sources, especially on the internet, which don't check out when you go to the original. I suspect that someone just made that chart up, but once that has happened once, it can easily proliferate.
