Ode to Straight Noses - Part 4

Yes, more straight noses.... If your FFS doctor tries to convince you that in order to pass or be beautiful, your nose needs to have a scooped bridge and be turned up like a pig snout (ok, my words, not theirs), remember these lovely women and their straight noses.

Rita Hayworth

Rita Hayworth

It's also worth mentioning that this hairline on Rita Hayworth is not natural. It was created through electrolysis. Her original hairline was lower in the corners. So in order to make her more attractive they gave her a hairline that FFS doctors would consider more masculine, but it worked.

High prenatal androgens cause boys to tilt their heads up when having their photos taken... or, Are square jaws a masculine trait? - Part 2

I was just looking at the abstract for the article "Second-to-fourth digit ratio and facial shape in boys: the lower the digit ratio, the more robust the face" by Meindl, Windhager, et al., and also looking at the accompanying photos which can be seen in an earlier post or here. And although I don't have access to the article, so cannot be sure, based on what I can see I'd say that the methods were faulty and the results should just be thrown out. The photographs were not taken consistently, which means they have no baseline to work from. No baseline means crap data.

In the first image below, the boy's head is tilted down and his ears line up at his eyebrows. In the middle photo, his ears line up below the eyebrows, and in the last photo his ears line up with his eyes. The difference can be seen by looking at his nose, too.

Here's a clue. It's not prenatal androgens.

What does this mean? It means I should start moonlighting writing scholarly articles for Proceedings of the Royal Society :) The image below shows the photographic evidence from the 2012 article, but with Angelina Jolie's face where the little boy face should go.

Photo showing that when Angelina's head is tilted down (look at the ears in the 1st photo), she suddenly has a more feminine, V-shaped face. And when her head is tilted up, a masculine, squarer jaw. But this is NOT due to prenatal androgens. It's just how things work, which is why taking photographs consistently is important. For more info, look up foreshortening.

Also, I returned to check the 2005 article and it doesn't include ears in the images so I cannot guess the accuracy of its findings. Under the 'Methods' section it says it just asked the men to look straight ahead. But its drawings don't have the telltale signs of inconsistency shown in the 2012 article. For example:

1. In the first image (shown above), the boys nose is pointy, in the last it isn't.
2. In the first image, the eyebrows are straignter (much like Angelina's) and the last image they are more arched (like Angelina's). 
3. In the first image the mouth is curved up, in the middle straight across, and in the last one curved down (again, like Angelina's)..

These are effects caused by tilting the head, and none of them appear to the degree they do in the image from the 2005 study shown below.

So, in a nutshell, the 2012 article's results cannot be trusted (just my opinion, of course). The 2005 article appears legit though, which would mean that higher levels of prenatal androgens result in a squarer, broader face whereas lower prenatal androgens result in a pointier chin and a face that is less square overall (longer than it is wide).

To be continued....

Are square jaws a masculine trait?

Recently I was asked my opinion on square jaws by a reader of this blog. I really didn't know where to start though. I thought I knew what the reader was getting at, but didn't think there was a good enough definition for the term, really. Sometimes "square" seems to refer to a square shaped face and at other times a defined jaw line.

What "square" means in the fields of medicine and anthropology...

But John Hawks, a paleoanthropologist and professor of anthropology, has a web site that gets to the point nicely. The angle of a person's jaw, shown below, differs somewhat between men and women. "In males, the angle [sic] is closer to 90 degrees. In females, this angle is greater, up to 110 -120 degrees." Hence the term "square jawed", I would assume.

mandibular or gonial angle

Other articles say this isn't a reliable determinant of gender though. Ethnicity and other factors play a role in determining the gonial angle. But since these articles are written by forensic anthropologists, their interest lies in being able to determine sex from skeletal remains. Our interests are different. We are looking at people face to face so have visual clues regarding age and ethnicity.

Jaw angle does affect face shape...

Another thing I learned from reading books on anthropology and forensic facial reconstruction is that the gonial angle definitely does affect that shape of one's face from the front. The squarer the jaw, the more likely the person will have a round or square face, as opposed to an oval or triangle-shaped face.

Androgens affect face shape...

We know this. We can SEE this. But here are some articles that show the difference prenatal testosterone makes. When a person's ring finger is longer than his or her index finger, this results in a lower 2D:4D ratio (2nd digit to 4th digit ratio) which signifies higher androgen exposure in the womb.

'Manly' Fingers Make For Strong Jawline in Young Boys (Note that this 2012 study had a very small sample size of 17. See the abstract here.)

Less prenatal androgens resulted in a more feminine, triangular, face shape, as seen on the left. This differs greatly from the masculine face, which is square-shaped.

Second to fourth digit ratio and face shape (2005 study of 106 volunteers)

Again, the more prenatal exposure to androgens, as seen on the far left, the squarer the face shape.

For your viewing pleasure, more non-scooped noses...

Rudolf Valentino (feel free to ignore his nose) and Natacha Rambova (who has a lovely jawline, that is both defined and feminine, to go with her great profile)

Carole Lombard's perfectly straight nose (although I can't say much for her jaw line)

Joan Crawford close-up by George Hurrell (the man's nose has a little bump, but hers is great)

More Joan Crawford

Ursula Andress

Keira Knightley (Her nose is turned up, but straight. Also, I know she's had rhinoplasty but don't know what her original profile was or if it was changed at all.)

Until later...
