The shape of your face may predict your sex drive
The findings have implications for both men and women.
Phrenology is dead and for good reason. This was a Victorian pseudoscience which claimed that one could tell personality traits and intellectual capacity from the size and shape of one's skull. It was used alongside eugenics to justify colonialism and slavery, to separate humans into superior and inferior races, and it's been wholly discredited. However, today through dynamic research in the fields of genetics, biology, and psychology, we're learning that certain aspects of the body do in fact tell us something about ourselves, mostly tendencies and behavioral traits.
For instance, last October researchers in the UK found that those who had a longer ring finger than pointer finger tended to be more promiscuous, while those with a longer pointer than ring finger tended to be more monogamous. A longer ring finger indicated receiving more testosterone at a critical point of development inside the womb. The results of this study are in dispute, however. Critics argue that researchers looked at finger length in one study sample and sexual behavior in another, and falsely compared the two.
One particularly interesting area of study is facial morphology, or how the size and shape of the face may related to certain behaviors, attitudes, and personality traits. A recent Canadian study has astonishing results. It finds that those with a wide face are more likely to have a strong sex drive and may even be more likely to cheat on their partner. The results were published in the journal Archives of Sexual Behavior.

Most of these kinds of studies have looked at male subjects. What researchers primarily focus on is facial width-to-height ratio (FWHR). This is the width of the face divided by the height of the upper face. The upper face is considered the distance between the brow and the upper lip.
Previous studies found that men with a squarer face tend to be more aggressive, more likely to engage in unethical behavior, tend to have more short-term sex partners, and are even more likely to have psychopathic traits, than those who had longer, thinner faces.
One study found pro hockey players with higher testosterone levels received more penalties. In this most recent one, testosterone may have played a role once again. But instead of in the womb, researcher believe this is the result of jolts of the sex hormone during puberty and other, pivotal developmental periods. It's also thought that testosterone helps us to formulate what desires and sexual attitudes we hold as adults.
Researchers at Nipissing University, Simon Fraser University, the University of Ottawa, and the Northern Ontario School of Medicine, all in Canada, conducted the study. It was led by Steven Arnocky. He's associate professor of psychology at Nipissing. So how is this sex hormone associated with our face? “It is suspected that testosterone helps shape cranio-facial structure," Arnocky said. And testosterone in turn is where the sex drive emanates from.
Arnocky and his team conducted two different studies on the subject. In the first, 148 heterosexual undergraduates, both male and female, participated. The gender breakdown was 48% male, 52% female. They were all Caucasian and each was in a romantic relationship at the time of the study.
A look at the diversity of face shapes. Categorizing celebrities' faces is a popular internet pastime, apparently: Gwyneth Paltrow (square face), Angelina Jolie (oval face), Cameron Diaz (round face), Reese Witherspoon (heart face).
Researchers measured their faces from photographs. They also had independent assessors evaluate participants' facial dimensions. In addition, each student filled out a questionnaire about their sex life and sex drive. What they found was a high width-to-height ratio equated with a high sex drive in both sexes.
The second study was modeled after the first. It took part in a different Canadian city, however. This time, 314 undergraduates took part. They answered a questionnaire which included questions about sexual orientation, how likely they might consider taking part in infidelity, and sociosexual questions. Authors defined sociosexual as, "a trait-based orientation toward sexuality that ranges between restricted and unrestricted."
Those who are restricted sociosexually may view intercourse outside the confines of a monogamous relationship as wrong or unseemly. The unrestricted however don't have a problem with casual sex or sex outside of monogamy. Men with a high FWHR tended to be more unrestricted sociosexually. They were also more willing to answer positively to questions which "anticipated infidelity." This wasn't the case with women.
So it seems women with wide, square faces are more likely to have a stronger sex drive. Men too, but they're also more likely to take part in casual sex and infidelity. In fact, another previous study also found a correlation in men between a higher FWHR and a likeliness to cheat. So could face shape become a predictor to one's outlook on sexuality? Yes, according to Arnocky. And that goes for both sexes. "Together, these findings suggest that facial characteristics might convey important information about human sexual motivations" he said.
Men with a square face shape may be more apt toward infidelity. But there are a lot of other factors at play. Getty Images.
This is the first study to link facial shape with sexual attitudes and behaviors, according to researchers. Still, it had its limitations. It only looked at college-age, straight, Caucasians for one. Do the same results carry over into other races, age brackets, and sexual orientations? Further studies will likely find out. Though they believe an injection of testosterone at proper times may cause a high FWHR, there's no biological evidence to confirm this, as this study was wholly observational.
And of course, there are many mitigating factors, like culture, religious belief, and so on, which come into play in how people view sex. How these modifiers further influence a person's behavior and sexual attitudes will be the subject of future research. We may even be able to tease out what evolutionary pressures were placed on our ancestors and how that influenced mating patterns within our species.

Richard Feynman once asked a silly question. Two MIT students just answered it.
Here's a fun experiment to try. Go to your pantry and see if you have a box of spaghetti. If you do, take out a noodle. Grab both ends of it and bend it until it breaks in half. How many pieces did it break into? If you got two large pieces and at least one small piece you're not alone.
But science loves a good challenge<p>The mystery remained unsolved until 2005, when French scientists <a href="http://www.lmm.jussieu.fr/~audoly/" target="_blank">Basile Audoly</a> and <a href="http://www.lmm.jussieu.fr/~neukirch/" target="_blank">Sebastien Neukirch </a>won an <a href="https://www.improbable.com/ig/" target="_blank">Ig Nobel Prize</a>, an award given to scientists for real work which is of a less serious nature than the discoveries that win Nobel prizes, for finally determining why this happens. <a href="http://www.lmm.jussieu.fr/spaghetti/audoly_neukirch_fragmentation.pdf" target="_blank">Their paper describing the effect is wonderfully funny to read</a>, as it takes such a banal issue so seriously. </p><p>They demonstrated that when a rod is bent past a certain point, such as when spaghetti is snapped in half by bending it at the ends, a "snapback effect" is created. This causes energy to reverberate from the initial break to other parts of the rod, often leading to a second break elsewhere.</p><p>While this settled the issue of <em>why </em>spaghetti noodles break into three or more pieces, it didn't establish if they always had to break this way. The question of if the snapback could be regulated remained unsettled.</p>
Physicists, being themselves, immediately wanted to try and break pasta into two pieces using this info<p><a href="https://roheiss.wordpress.com/fun/" target="_blank">Ronald Heisser</a> and <a href="https://math.mit.edu/directory/profile.php?pid=1787" target="_blank">Vishal Patil</a>, two graduate students currently at Cornell and MIT respectively, read about Feynman's night of noodle snapping in class and were inspired to try and find what could be done to make sure the pasta always broke in two.</p><p><a href="http://news.mit.edu/2018/mit-mathematicians-solve-age-old-spaghetti-mystery-0813" target="_blank">By placing the noodles in a special machine</a> built for the task and recording the bending with a high-powered camera, the young scientists were able to observe in extreme detail exactly what each change in their snapping method did to the pasta. After breaking more than 500 noodles, they found the solution.</p>

What possible application could this have?<p>The snapback effect is not limited to uncooked pasta noodles and can be applied to rods of all sorts. The discovery of how to cleanly break them in two could be applied to future engineering projects.</p><p>Likewise, knowing how things fragment and fail is always handy to know when you're trying to build things. Carbon Nanotubes, <a href="https://bigthink.com/ideafeed/carbon-nanotube-space-elevator" target="_self">super strong cylinders often hailed as the building material of the future</a>, are also rods which can be better understood thanks to this odd experiment.</p><p>Sometimes big discoveries can be inspired by silly questions. If it hadn't been for Richard Feynman bending noodles seventy years ago, we wouldn't know what we know now about how energy is dispersed through rods and how to control their fracturing. While not all silly questions will lead to such a significant discovery, they can all help us learn.</p>
Reaching beyond the stereotypes of meditation and embracing the science of mindfulness.
- There are a lot of misconceptions when it comes to what mindfulness is and what meditation can do for those who practice it. In this video, professors, neuroscientists, psychologists, composers, authors, and a former Buddhist monk share their experiences, explain the science behind meditation, and discuss the benefits of learning to be in the moment.
- "Mindfulness allows us to shift our relationship to our experience," explains psychologist Daniel Goleman. The science shows that long-term meditators have higher levels of gamma waves in their brains even when they are not meditating. The effect of this altered response is yet unknown, though it shows that there are lasting cognitive effects.
- "I think we're looking at meditation as the next big public health revolution," says ABC News anchor Dan Harris. "Meditation is going to join the pantheon of no-brainers like exercise, brushing your teeth and taking the meds that your doctor prescribes to you." Closing out the video is a guided meditation experience led by author Damien Echols that can be practiced anywhere and repeated as many times as you'd like.
Just what every arachnophobe needed to hear.
- A new study suggests some spiders might lace their webs with neruotoxins similar to the ones in their venom.
- The toxins were shown to be effective at paralyzing insects injected with them.
- Previous studies showed that other spiders lace their webs with chemicals that repel large insects.
