(Note: Testosterone differences between the rates are negligible, not high enough to account for differences in prostate cancer mortality. Black males have 2.5 to 4.9 times higher testosterone than white males (see Richard et al, 2014) and my article on the cause for the difference in prostate cancer mortality. The difference in testosterone between the races is not too high, as is commonly believed. Old studies with small ns get cited, when bigger, more robust analyses show the opposite, with a smaller difference. A difference that cannot be attributed to racial differences in prostate cancer.)
(Note 2, 6/23/17: This post is getting a ton of traffic so I need to clarify some things.
Here is a quote from Mazur (2016):
The pattern [high testosterone] is not seen among teenage boys or among females.
There is no indication of inordinately high T among young black women with low education.
I cringed pretty hard reading the comments below; I was just like PumpkinPerson arguing something that is not true. However, I am more then capable of admitting that I am wrong with suffcient evidence. Read the most recent posts on testosterone on this blog for more information. End Edit)
It is known that blacks have the highest levels of testosterone out of the major races of humanity. However, what’s not known is that black women have higher rates than white women. The same evolutionary factors that make it possible for black men to have high testosterone make it possible for women as well.
Most people don’t know this, but vitamin D isn’t really a vitamin; it’s a steroid hormone. Higher levels of testosterone occur due to increased exposure to the sun. Of course, the Middle East gets more sunlight than does Europe, so their levels of testosterone will be higher due to increased vitamin D, which in turn increases testosterone, causing more acts of aggression. Vitamin D supplementation could possibly (we know it does) raise testosterone levels. Of course, this is the case, seeing as vitamin D comes from the sun, and the more sun you get, the more Vitamin D you get, which increases testosterone levels. Those populations closer to the equator get more vitamin D from the sun’s rays, and thusly have higher levels of testosterone, on average.
Black women are more androgynous (personal observation, you can’t tell if they’re a man or woman from further away), and are more prone to get in to shouting matches/fights with other men or women. This is the high testosterone at work. Those with higher levels of test are more aggressive and have a more manly look as a result.
Moreover, the higher natural levels of testosterone found in black women are directly responsible for the reason why black men have higher levels of testosterone. Since circulating hormones matter for a woman’s child invitro, it would stand to reason that since black babes are in a woman with higher natural levels of testosterone, that this would pass on to the babe. This is exactly what is observed. One study showed that black women had 50 percent higher testosterone than white women in early pregnancy!! Ross, the head researcher of the study, speculates that “this increased hormonal exposure in utero might reset the so-called “gonadostat feed-back loop,” which regulates testosterone secretion, to a higher level.” With what we know about hormones and babes in the womb, this is a viable hypothesis.
Finally, Satoshi Kanazawa noted in this study that black women were not seen as attractive as women from other races. He says women, on average, are more attractive than men: EXCEPT BLACK WOMEN. The data shows black women as not being statistically different from the average, and far less attractive than whites, Asians, and Native American women.
The cause is higher testosterone. Kanazawa says that the cause for this is due to the mean BMI of black women being 28.5 among black women and 26.1 among non-black women. Though he says that’s not the reason why black women are less physically attractive. Black women have lower levels of intellect net of BMI. Even the racial differences in intelligence don’t account for these differences. Black women are STILL less physically attractive, net of BMI and intelligence. Kanazawa says: “Net of intelligence, black men are significantly more physically attractive than nonblack men.”
Why is that? To be blunt, black women look more like men than women due to their higher levels of testosterone. The amount of crying all throughout the Internet after Kanazawa published his paper says it all: Racist!! Sexist!! Except, they couldn’t respond to the data so of course, as is usually the case with racial/sex differences, bury it, forget about it and proclaim the one who said these uncomfortable truths is a “racist”. Kanazawa ends up concluding that testosterone differences are the only cause for these differences. With blacks having the highest testosterone out of all the races, black women obviously have higher rates of testosterone than white women. Those women with higher levels of testosterone have more masculine features, therefore making them less attractive.
My personal answer as to why black women are less attractive is due to testosterone obviously. But, we as humans can subconsciously detect things such as this. Since high levels of testosterone are correlated with numerous variables that then become masculinzied in black women, this is one very huge reason in my opinion.
Lewis (2010) says in his study Who is the fairest of them all? Race, attractiveness and skin color sexual dimorphism:
Previous research has suggested that perceived attractiveness and personality are affected by the race such that White faces are more attractive but less masculine than Black faces. Such studies, however, have been based on very small stimulus sets. The current study investigated perceived attractiveness and personality for 600 Black, White and mixed-race faces. Many of the investigated personality traits were correlated with race when rated by White participants. Attractiveness specifically was greater for Black male faces than White male faces and among mixed-race faces. Blackness correlated with increased attractiveness. A reverse pattern was found for female faces with Whiteness being associated with attractiveness. The results are discussed in terms of the sexual dimorphism demonstrated in skin color.
