Flashback Friday.

Back when I was in high school and college, I learned that one of the major things that separated humans from other species was culture. The ability to develop distinct ways of living that include an understanding of symbols, language, and customs unique to the group was a specifically human trait.

And, ok, so it turned out that other species had more complex communication systems than we thought they did, but still, other animals were assumed to behave according to instinct, not community-specific cultures.

But as with so many things humans have been convinced we alone possess, it’s turning out that other species have cultures, too. One of the clearest examples is the division of orcas into two groups with distinct customs and eating habits; one eats mammals while the other is pescetarian, eating only fish. Though the two groups regularly come in contact with each other in the wild, they do not choose to intermingle or mate with one another. Here’s a video:

Aside from the obvious implications for our understanding of culture, this brings up an issue in terms of conservation. Take the case of orcas. Some are suggesting that they should be on the endangered species list because the population has declined. What do we do if it turns out at some point that, while the overall orca population is not fully endangered, one of the distinct orca cultural groups is? Is it enough that killer whales still exist, or do we need to think of the cultures separately and try to preserve sufficient numbers of each? In addition to being culturally different, they are functionally non-interchangeable: each group has a different effect on food chains and ecosystems.

Should conservation efforts address not just keeping the overall population alive and functioning, but ensure that the range of cultural diversity within a species is protected? If this situation occurred, should we declare one orca culture as endangered but not the other? Are both ecological niches important?

I love these questions. If we recognize that creatures can have cultures, it challenges our sense of self, but also brings significantly more complexity to the idea of wildlife preservation.

A new study finds that people with high “justice sensitivity” are using logic, not emotions.  Subjects were put in a fMRI machine, one that measures ongoing brain activity and shown videos of people acting kindly or cruelly toward a homeless person.

Some respondents reacted more strongly than others — hence the high versus low justice sensitivity — and an analysis of the high sensitivity individuals’ brain activity showed that they were processing the images in the parts of the brain where logic and rationality live.   “Individuals who are sensitive to justice and fairness do not seem to be emotionally driven,” explained one of the scientists, “Rather, they are cognitively driven.”

Activists aren’t angry, they reasonably object to unjust circumstances that they understand all too well.

According to an article by Megan Garber at The Atlantic, they did it for the drugs.

Starting in the 1300s, Europeans developed a taste for hallucinogenic drugs. Unfortunately, ingesting them often caused nausea and vomiting. Absorbing them through the skin came with fewer side effects and delivering them through the mucous membranes of the female genitals was ideal.

A physician quoted at The Guardian says the claim is medically sound:

Ointment would have been very effective as a delivery method… Mucous membranes are particularly good at transporting drugs – that’s why cocaine is snorted… Vaginal application would be pretty efficient, and the effects of the drugs would be noticeable quite rapidly.

According to legend, then, witches would coat the handle of a broom — a convenient household item — lift their skirts and get high.

The women who trafficked in hallucinogenic substances were often accused of being witches.  Or, conversely, women accused of being witches were also accused of making magic ointments (from the fat of murdered children, no less). And witch experts in the 15th century claimed that they used these ointments not just to get high, but to get high; that is, that they literally flew using ointments.

Hence, witches on brooms.

Forgive me, because this is probably better left to Cyborgology, but something amazing is happening here. In the video below, nesting swallows become trapped in a building when they add doors. The birds soon learn, though, that they can get the doors to automatically open by triggering the motion sensors. This is a story, obviously, of how smart birds are, but here’s what struck me: we often think about human technology as for humans. In this case, however, birds adapted the technology for their own very similar needs (to get in and out).

If the workers had installed an older human technology — plain old doors — the birds would have been out of luck because they don’t have thumbs and the strength to manipulate an environment built for humans. But motion activated doors make both thumbs and strength irrelevant, so now birds are our functional equals.

This is fascinating, yeah? Our technology has advanced to the point where we’re potentially undermining our own evolutionary advantages. I’m not putting a moral judgment on it. I think morality is firmly on the side of non-fitness based decisions (eh em, social Darwinism). If one wants to theorize the relationship between animals, technology, and what it means to be human, however, this looks like gold to me.

Okay Cyborgology, your turn.

Flashback Friday.

This remarkable newspaper article illustrates how skin color (which is real) gets translated into categorical racial categories (which are not).  The children in the images below — Kian and Remee Hodgson — are fraternal twins born to two bi-racial parents:

The story attempts to explain the biology:

Skin colour is believed to be determined by up to seven different genes working together. If a woman is of mixed race, her eggs will usually contain a mixture of genes coding for both black and white skin. Similarly, a man of mixed race will have a variety of different genes in his sperm. When these eggs and sperm come together, they will create a baby of mixed race.  But, very occasionally, the egg or sperm might contain genes coding for one skin colour. If both the egg and sperm contain all white genes, the baby will be white. And if both contain just the versions necessary for black skin, the baby will be black.

Fair enough.

But then the journalist makes a logical leap from biological determinants of skin color to racial categories. Referring now to genes for skin color as “black” and “white” genes, she writes: “Baby Kian must have inherited the black genes from both sides of the family, whilst Remee inherited the white ones.”  And, of course, while both children are, technically, mixed race*, the headline to the story, “Black and White Twins,” presents them as separate races.

We’re so committed to racial differences that the mother actually speaks about their similarities as if it is surprising that twins of different “races” could possibly have anything in common.  She says:

There are some similarities between them. They both love apples and grapes, and their favourite television programme is Teletubbies.”

This is also a nice example of a U.S.-specific racial logic. This might not have been a story in Brazil at all, where racial categories are determined more by color alone and less by who your parents are.  It is not uncommon there to have siblings of various racial designations.

The twins, by the way, are seven now.

* Of course, identifying them as mixed race also re-inscribes racial categories in that you must believe in two or more racial categories to believe that it is possible to mix them.

Last year I was tickled to write about a cool study showing that, if a person grows up with a language that writes from left to right, then numerical estimates of things like weight or height will, on average, be smaller when a person is imperceptibly and unknowingly leaning to the left.  Seriously, it’s awesomely fun research and you can read about it here.

Today I have the equally fun pleasure of sharing a research study on weight and importance.  It turns out that, when people are holding something heavy, they will report an issue to be more serious, compared to when they are holding something lighter.

Some examples come from a set of studies by psychologist Nils Jostmann and colleagues.

• In the first study, European participants were asked to guess the value of various foreign currency in euros.  Some were given a heavy clipboard on which to mark their estimates, and others a light clipboard.  Those who held the light clipboard estimated, on average, lesser values.

• In a second study, subjects were asked to estimate the importance of college students having a voice in a decision-making process involving grants to study abroad.  Participants with the heavy clipboard felt that it was more important for students to have a voice.

• In a third, subjects were asked to report whether they liked their city after reading a biography of the mayor and indicating how the felt about him.  If they carried the heavy clipboard, there was a relationship between their estimation of the mayor and that of the city, but not if they carried a light clipboard.  In this case, the importance of their feelings about the mayor weighed heavier on their evaluation of the city if the clipboard was heavy.

What is driving these findings?

In English, and several other languages as well, weight is used as metaphor to signify importance.  The authors hypothesized that this abstraction can be triggered by concrete experiences of weight, like holding something heavy.  They call this “embodied cognition.”  Our thinking is affected by the connection between our bodies, their relationship with objects, and metaphors in our minds.

Another nail in the Descartian mind-body dualism coffin.

“Carrie is largely about how women find their own channels of power, but also what men fear about women and women’s sexuality. Writing the book in 1973 and only three years out of college, I was fully aware of what Women’s Liberation implied for me and others of my sex. Carrie is woman feeling her powers for the first time and, like Samson, pulling down the temple on everyone in sight at the end of the book.”

– Stephen King, Danse Macabre

Most feminist criticism of Stephen King’s Carrie has focused on the male fear of powerful women that the author said inspired the film, with the anti-Carrie camp finding her death at the end to signify the defeat of the “monstrous feminine” and therefore a triumph of sexism. But Stephen King’s honesty about what inspired his 1973 book notwithstanding, Carrie is as much an articulation of a feminist nightmare as it is of a patriarchal one, with neither party coming out on top.

The rise of Second Wave feminism in the ’70s posed serious threats to the patriarchal order — as well it should have. But even for those who think change is not only necessary but good, change can be pretty scary. This, with a hat tip to the universality of being bullied, is one of the reasons Carrie scares everyone.

While men in the ’70s felt threatened by the unprecedented numbers of women standing up for themselves and attempting such radical social changes as being recognized as equal under the law, women themselves must have felt some anxiety that the obstacles to fully realizing themselves might be too big to conquer. The story therefore resonates with men in terms of the fear of (metaphorical) castration prompted by changing gender roles, and with women in terms of the fear that no matter how powerful we become, social forces are still so aligned against us that fighting back might destroy not just the patriarchy but ourselves.

Feminism was not the only thing on the rise in the ’70s: so was Christian fundamentalism. In 1976, the year that the original movie debuted, 34 percent of Protestant Americans told the Gallup Poll that they had had born-again experiences, leading George Gallup himself to declare 1976 the Year of the Evangelical. In fact evangelism, then as now — when 41 percent of Americans report being born again — was one of feminism’s more formidable foes, one of those very social forces that would rather destroy women than see them powerful.

The triggering event of Carrie–the infamous shower scene–is a product of the meeting of these two forces. Because of a fundamentalist Christian worldview in which menstruation is not simply a biological process but rather evidence of Eve’s original sin being visited upon her daughters,Carrie‘s mother does nothing to prepare her for getting her period. When she starts bleeding at school, Carrie naturally panics, and as a result faces the scorn of her peers — who laugh at her for not knowing what’s happening — and the scorn of her mother, who believes that “After the blood the boys come. Like sniffing dogs, grinning and slobbering, trying to find out where that smell is.”

I can’t believe I’m about to go all Freudian here, but for the male viewer the shock of seeing unexpected blood between one’s legs clearly represents a fear of castration–a literal embodiment of King’s anxieties about feminism. From the woman’s perspective, the menstrual blood obviously signifies Carrie’s maturation — coming into her power — which has been marred by fundamentalism.

Without making the new remake of the movie any more violent, director Kimberly Peirce emphasizes the imagery of this inciting event by adding waaaaay more blood to her Carrie. When Carrie gets her period in the shower, there’s more blood than in Brian De Palma’s film. When Carrie gets some of that blood on her gym teacher, which happens in both films, Peirce adds more of it, and the camera lingers on it longer and returns to it more often.

When Carrie’s mother locks her in the closet, Peirce has the crucifix bleed–something that doesn’t happen in the first movie. The blood of the crucifix connects Carrie’s first period to the suffering of Christ, deepening the relationship between debased femininity and religion.

Then, when Carrie gets pig blood dumped on her head at the prom, there’s not just more of it in the second film: Pierce shows the blood landing on her in slow motion three times. This final deluge of blood echoes a scene that Pierce added to the beginning of the movie, in which Carrie’s mother endures the bloody birth of her daughter. Carrie, then, is essentially born again at the prom, and the devastation she wreaks can be read as a result not of her feminine power but of the corruption of it by religion.

Peirce told Women and Hollywood that her goal was to make Carrie as sympathetic as possible. She removes the male gaze aspect of the original shower scene, in which many of the girls are naked and the long, slow shots of Carrie’s body are rather pornified. She makes sympathy for Carrie’s primary nemesis at school pretty much impossible by changing her from an angry girl in an abusive relationship to a sociopath without a conscience. In the new film, Carrie even has the strength to challenge her mother’s theology. Her prom date is more likeable and Peirce uses his death–something De Palma doesn’t reveal until the end — as further motivation for Carrie’s rampage.

None of this changes the fact that Carrie dies at the end, but it does foreground the idea that the message doesn’t have to be that powerful women are indeed dangerous. It can be that fundamentalism is dangerous to women.

If you’re a feminist, I say go see Carrie. Watching her be destroyed — but not without taking out a lot of the patriarchy with her — and then, as a viewer, emerging again into the sunlight unscathed, allows feminists to process some of our deepest fears about what we’re up against. Then we can get on with making the world a place where religious beliefs don’t corrupt our sexuality, where women don’t have to destroy themselves to be powerful and where women’s equality doesn’t trigger men’s fear of their own doom.

If I have one thing to say about Holly Grigg-Spall’s new book, Sweetening the Pill: How We Got Hooked On Hormonal Birth Control, it’s that it brings together ideas in creative ways and comes out with conclusions that are new to me.

The book is an interrogation of the popularity of hormonal birth control in the U.S.  In one argument, Grigg-Spall begins with the fact that women’s bodies are a fraught topic. For hundreds of years, the female body has been offered as proof of women’s inferiority to men.  Feminists have had two options: (1) embrace biological difference and claim equality based on essential femaleness or (2) reject difference and claim equality based on sameness.

Largely, Grigg-Spall argues, the latter has won out as the dominant feminist strategy. Accordingly, all things uniquely female become suspect; they are possible traitors to the cause.  This includes ovulation, menstruation, and the mild mood swings that tend to accompany them (men have equivalent mood swings, by the way, they’re just daily and seasonal instead of monthly-ish).

Hormonal birth control, then, can be seen as a way to eliminate some of the things about us that make us distinctly “female.”  “Science is making us better,” the message goes.  By getting rid of our supposedly feminine frailties, “we are [supposedly] becoming better humans…”  A quick look at birth control pill advertising reveals that this goes far beyond preventing pregnancy.  Commercials frequently claim other benefits that conform to socio-cultural expectations for women: reduced PMS, clearer skin, and bigger breasts.  This Yaz commercial, for example, claims that the pill also cures acne, irritability, moodiness, anxiety, appetite, headaches, fatigue, and bloating.
