Sociologists Martin Weinberg and Colin Williams wanted to know. They and their team interviewed 172 college students about their habits and concerns about farting and pooping. They published their results in an article called Fecal Matters. They discovered that everybody farts and everybody cares, but not everyone cares all the time or equally.

They separated their results by gender and sexual orientation. When they asked people if they were worried that the hearer would “feel disgust,” heterosexual women were most likely to agree and heterosexual men the least, with non-heterosexual men and women in the middle, but flipped such that men were more worried than women.

Heterosexual men were the most likely to think it was funny and the most likely to engage in “intentional flatulence.” Almost a quarter said that they “often” did so, whereas only 7 percent of heterosexual women said the same. “Guys would say it’s raunchy and then say ‘Nice one,’” explained one heterosexual guy, “because if it’s strong it’s more manly. You know, because women would not try to clear a room with a fart.” Heterosexual women felt like they were violating gender norms if their farts were stinky: “The worse it stinks,” said one, “the nastier they think I am.”

Heterosexual women were the most concerned that it would affect their relationship with the hearer. They were also the most likely to do things to reduce the likelihood that others would detect their bathroom activities, like go into another room to pass gas or let their stool out slowly to avoid a kerplunk. Two thirds said they would wait until they were alone to poop and only women reported flushing repeatedly to ensure that the sights and smells of their defecation had disappeared.

As a counter example, one of the heterosexual men interviewed said that the only thing he was willing to do to protect others from his bathroom activities was close the door.

Non-heterosexual men were an interesting conundrum. They were as likely as heterosexual men to think that the hearer would think it was funny, but the least likely to engage in intentional flatulence and the most likely to make sure that when they poop, they do so alone.

Non-heterosexual women were also a conundrum. They were the least likely to think the hearer would laugh at a fart, but second only to heterosexual men in the practice of farting on purpose to get a reaction.

This study is a great example of what social scientists call doing gender, modifying our behavior to conform to gendered expectations. Generally, women are expected to have better control of their body, to be more polite, and to avoid offending others. All of these things are consistent with being more discreet with farts and poops.

The interesting data from non-heterosexual men and women may be explained by the conflation of sexual object choice and the performance of gender. It’s not universally this way, but in the U.S. today gay men are feminized and lesbians masculinized. This is a stereotype, but also gives non-heterosexual men and women some permission to deviate from gender rules. As one non-heterosexual man explained:

Only around people that I’m regularly naked with would I be comfortable with them knowing what I was doing in the bathroom. I’m on the self-prescribed “pretty pill”—where you don’t fart, sweat, burp, or use the bathroom… I learned it from my diva friends.

Similarly, some non-heterosexual women may feel a little less pressure to be as girly or girly all the time.

Flashback Friday.

Joan Jacob Brumberg’s fantastic book, Fasting Girls: The History of Anorexia Nervosa, is an excellent example of the benefits of sociologically-inspired history.  Brumberg begins by explaining that girls who starved themselves have been recorded in many historical epochs, but the way in which societies have made sense of that starvation has varied.

Today we medicalize self-starvation; we call it a mental illness and we name it “anorexia nervosa.”

In Medieval Europe, fasting girls were labeled with the term “anorexia mirabilis”; these girls were seen as miracles, able to survive on spiritual devotion alone. During the Victorian Era, people would pilgrimage to these fasting girls and leave offerings.  A famous fasting girl could be a financial boon to a struggling family.

Fasting Girl Mollie Fancher in 1887:

During the nineteenth century, medical doctors and psychiatrists (who generally saw religion as a threat to their nascent authority) argued that the fasting girls were impossibilities, that no one could survive without food. The competition between medicine and religion became so intense that doctors became intent on proving that these fasting girls were not surviving on holiness, but were sneaking food. In several cases, doctors staked out fasting girls, watching her to make sure that she did not eat, and these girls, relentless in the illusion, sometimes died.

In any case, I thought of Brumberg’s book when I came across a story about Prahlad Jani, an Indian man who claims that he has not had any food or drink for 70 years, surviving on “spiritual life force” instead.

In 2003 and 2010, Jani’s claims were tested by physicians. In the latest round, Indian military scientists held him in a hospital, watching him to ensure he did not eat or drink.  Unlike the doctors in the Victorian era, however, who wanted the girls to fail, these doctors think Jani might hold a secret that will be useful for the military and they’re hoping that, by watching, they will be able to discover it.

They released him after 15 days. As they did in 2003, they said that his tests came back normal despite complete abstinence from food and water.

Social and biological scientists agree that race and ethnicity are social constructions, not biological categories.  The US government, nonetheless, has an official position on what categories are “real.”  You can find them on the Census:

These categories, however real they may seem, are actually the product of a long process. Over time, the official US racial categories have changed in response to politics, economics, conflict, and more. Here’s some highlights.

In the year of the first Census, 1790, the race question looked very different than it does today:

Free white males
Free white females
All other free persons (included Native Americans who paid taxes and free blacks)
And slaves

By 1870 slavery is illegal and the government was newly concerned with keeping track of two new kinds of people: “mulattos” (or people with both black and white ancestors) and Indians:

White
Black
Mulatto
Indian (Native Americans)

Between 1850 and 1870 6.5 million Europeans had immigrated and 60,000 Chinese.  Chinese and Japanese were added for the 1880 Census.

By 1890, the U.S. government with obsessed with race-mixing.  The race question looked like this:

White
Black (3/4^th or more “black blood”)
Mulatto (3/8^th to 5/8^th “black blood”)
Quadroons (1/4^th “black blood”)
Octoroons (1/8^th or any trace of “black blood”)
Indian
Chinese
Japanese

This year was the only year to include such fine-tuned mixed-race categories, however, because it turned out it wasn’t easy to figure out how to categorize people.

In the next 50 years, the government added and deleted racial categories. There were 10 in 1930 (including “Mexican” and “Hindu”) and 11 in 1940 (introducing “Hawaiian” and “Part Hawaiian”).  In 1970, they added the “origin of descent” question that we still see today.  So people are first asked whether they are “Hispanic, Latino, or Spanish” and then asked to choose a race.

You might immediately think, “But what do these words even mean?”  And you’d be right to ask.  “Spanish” refers to Spain; “Latino” refers to Latin America; and “Hispanic” is a totally made up word that was originally designed to mean “people who speak Spanish.”

Part of the reason we have the “Hispanic” ethnicity question is because Mexican Americans fought for it.  They thought it would be advantageous to be categorized as “white” and, so, they fought for an ethnicity category instead of a racial one.

Funny story:  The US once included “South American” as a category in the “origin of descent” question.  That year, over a million residents southern U.S. states, like Alabama and Mississippi checked that box.

2000 was the first year that respondents were allowed to choose more than one race. They considered a couple other changes for that year, but decided against them. Native Hawaiians had been agitating to be considered Native Americans in order to get access to the rights and resources that the US government has promised Native Americans on the mainland. The government considered it for 2000, but decided “no.” And whether or not Arab American should be considered a unique race or an ethnicity was also discussed for that year. They decided to continue to instruct such individuals to choose “white.”

The changing categories in the Census show us that racial and ethnic categories are political categories. They are chosen by government officials who are responding not to biological realities, but to immigration, war, prejudice, and social movements.

Flashback Friday.

The AP has an interesting website about wildfires from 2002 to 2006. Each year, most wildfires occurred west of the Continental Divide. Many of these areas are forested. Others are desert or shortgrass prairie.

There are a lot of reasons for wildfires–climate and ecology, periodic droughts, humans. The U.S. Fish and Wildlife Service reports that in the Havasu National Wildlife Refuge, the “vast majority” of wildfires are due to human activity. Many scientists expect climate change to increase wildfires.

Many wildfires affect land managed by the Bureau of Land Management. For most of the 1900s, the BLM had a policy of total fire suppression to protect valuable timber and private property.

Occasional burns were part of forest ecology. Fires came through, burning forest litter relatively quickly, then moving on or dying out. Healthy taller trees were generally unaffected; their branches were often out of the reach of flames and bark provided protection. Usually the fire moved on before trees had ignited. And some types of seeds required exposure to a fire to sprout.

Complete fire suppression allowed leaves, pine needles, brush, fallen branches, etc., to build up. Wildfires then became more intense and destructive: they were hotter, flames reached higher, and thicker layers of forest litter meant the fire lingered longer.

As a result, an uncontrolled wildfire was often more destructive. Trees were more likely to burn or to smolder and reignite a fire several days later. Hotter fires with higher flames are more dangerous to fight, and can also more easily jump naturally-occurring or artificial firebreaks. They may burn a larger area than they would otherwise, and thus do more of the damage that total fire suppression policies were supposed to prevent.

In the last few decades the BLM has recognized the importance of occasional fires in forest ecology. Fires are no longer seen as inherently bad. In some areas “controlled burns” are set to burn up some of the dry underbrush and mimic the effects of naturally-occurring fires.

But it’s not easy to undo decades of fire suppression. A controlled burn sometimes turns out to be hard to control, especially with such a buildup of forest litter. Property owners often oppose controlled burns because they fear the possibility of one getting out of hand. So the policy of fire suppression has in many ways backed forest managers into a corner: it led to changes in forests that make it difficult to change course now, even though doing so might reduce the destructive effects of wildfires when they do occur.

Given this, I’m always interested when wildfires are described as “natural disasters.” What makes something a natural disaster? The term implies a destructive situation that is not human-caused but rather emerges from “the environment.” As the case of wildfires shows, the situation is often more complex than this, because what appear to be “natural” processes are often affected by humans… and because we are, of course, part of the environment, despite the tendency to think of human societies and “nature” as separate entities.

Lots of time and care consideration goes into the production of new superheroes and the revision of time-honored heroes. Subtle features of outfits aren’t changed by accident and don’t go unnoticed. Skin color also merits careful consideration to ensure that the racial depiction of characters is consistent with their back stories alongside other considerations. A colleague of mine recently shared an interesting analysis of racial depictions by a comic artist, Ronald Wimberly—“Lighten Up.”

“Lighten Up” is a cartoon essay that addresses some of the issues Wimberly struggled with in drawing for a major comic book publisher. NPR ran a story on the essay as well. In short, Wimberly was asked by his editor to “lighten” a characters’ skin tone — a character who is supposed to have a Mexican father and an African American mother.  The essay is about Wimberly’s struggle with the request and his attempt to make sense of how the potentially innocuous-seeming request might be connected with racial inequality.

In one panel of the cartoon, you can see Wimberly’s original color swatch for the character alongside the swatch he was instructed to use for the character.

Digitally, colors are handled by what computer programmers refer to as hexadecimal IDs. Every color has a hexademical “color code.” It’s an alphanumeric string of 6 letters and/or numbers preceded by the pound symbol (#).  For example, computers are able to understand the color white with the color code #FFFFFF and the color black with #000000. Hexadecimal IDs are based on binary digits—they’re basically a way of turning colors into code so that computers can understand them. Artists might tell you that there are an infinite number of possibilities for different colors. But on a computer, color combinations are not infinite: there are exactly 16,777,216 possible color combinations. Hexadecimal IDs are an interesting bit of data and I’m not familiar with many social scientists making use of them (but see).

There’s probably more than one way of using color codes as data. But one thought I had was that they could be an interesting way of identifying racialized depictions of comic book characters in a reproducible manner—borrowing from Wimberly’s idea in “Lighten Up.” Some questions might be:

• Are white characters depicted with the same hexadecimal variation as non-white characters?
• Or, are women depicted with more or less hexadecimal variation than men?
• Perhaps white characters are more likely to be depicted in more dramatic and dynamic lighting, causing their skin to be depicted with more variation than non-white characters.

If any of this is true, it might also make an interesting data-based argument to suggest that white characters are featured in more dynamic ways in comic books than are non-white characters. The same could be true of men compared with women.

Just to give this a try, I downloaded a free eye-dropper plug-in that identifies hexadecimal IDs. I used the top 16 images in a Google Image search for Batman (white man), Amazing-man (black man), and Wonder Woman (white woman). Because many images alter skin tone with shadows and light, I tried to use the eye-dropper to select the pixel that appeared most representative of the skin tone of the face of each character depicted.

Here are the images for Batman with a clean swatch of the hexadecimal IDs for the skin tone associated with each image below:

Below are the images for Amazing-man with swatches of the skin tone color codes beneath:

Finally, here are the images for Wonder Woman with pure samples of the color codes associated with her skin tone for each image below:

Now, perhaps it was unfair to use Batman as a comparison as his character is more often depicted at night than is Wonder Woman—a fact which might mean he is more often depicted in dynamic lighting than she is. But it’s an interesting thought experiment.  Based on this sample, two things that seem immediately apparent:

• Amazing-man is depicted much darker when his character is drawn angry.
• And Wonder Woman exhibits the least color variation of the three.

Whether this is representative is beyond the scope of the post.  But, it’s an interesting question.  While we know that there are dramatically fewer women in comic books than men, inequality is not only a matter of numbers.  Portrayal matters a great deal as well, and color codes might be one way of considering getting at this issue in a new and systematic way.

While the hexadecimal ID of an individual pixel of an image is an objective measure of color, it’s also true that color is in the eye of the beholder and we perceive colors differently when they are situated alongside different colors. So, obviously, color alone tells us little about individual perception, and even less about the social and cultural meaning systems tied to different hexadecimal hues. Yet, as Wimberly writes,

In art, this is very important. Art is where associations are made. Art is where we form the narratives of our identity.

Beyond this, art is a powerful cultural arena in which we form narratives about the identities of others.

At any rate, it’s an interesting idea. And I hope someone smarter than me does something with it (or tells me that it’s already been done and I simply wasn’t aware).

Strawberry shortcake, chocolate covered strawberries, strawberry daiquiris, strawberry ice cream, and strawberries in your cereal. Just delicious combinations of strawberries and things? Of course not.

According to an investigative report at The Guardian, in the first half of the 1900s, Americans didn’t eat nearly as many strawberries as they do now. There weren’t actually as many strawberries to eat. They’re a fragile crop, more prone than others to insects and unpredictable weather.

In the mid-1950s, though, scientists at the University of California began experimenting with a poison called chloropicrin. Originally used as a toxic gas in World War I, scientists had learned that it was quite toxic to fungus, weeds, parasites, bacteria, and insects. By the 1960s, they were soaking the soil underneath strawberries with the stuff. Nearly every strawberry field in California — a state that produces 80% of our strawberries — was being treated with chloropicrin or a related chemical, methyl bromide.

In the meantime, a major grower had collaborated with the University, creating heartier varieties of strawberries and ones that could be grown throughout the year. These developments doubled the strawberry crop. This was more strawberries than California — and the country — had ever seen. The supply now outpaced the demand.

Enter: Strawberry Shortcake.

Strawberry Shortcake was invented by American Greetings, the greeting card company. She was created in cahoots with the strawberry growers association. They made a deal, just one part of a massive marketing campaign to raise the profile of the strawberry.

The head of the association at the time, Dave Riggs, aggressively marketed tie-ins with other products, too: Bisquick, Jello, Corn Flakes, and Cheerios. Cool Whip still has a strawberry on its container and its website is absolutely dotted with the fruit.

Riggs went to the most popular women’s magazines, too — Ladies’ Home Journal, Redbook, and Good Housekeeping — and provided them with recipe ideas. It was an all out strawberry assault on America.

It worked. “Today,” according to The Guardian, “Americans eat four times as many fresh strawberries as they did in the 1970s.” We think it’s because we like them, but is it?

Most Americans, when asked if they are affected by advertising, will say “not really.” They think other people are influenced by cultural messages, but that they are somehow immune.

Whether people are shaped by the media they consume seems to be a perpetual question. The fact that billions of dollars are spent every year attempting to influence us is probably a sign that advertisers know it works. Scientists get in on the action, asking pressing questions like: Do violent video games increase violence in real life? Do sexy, thin models hurt girls’ self-esteem? We do the studies and the answers are often inconclusive, probably because of how complicated the relationships are.

Psychologist Stefano Ghirlanda and his colleagues asked a slightly simpler question: Do celebrity dogs influence the popularity of dog breeds? They looked at 100 movies with prominent dog characters from 1939 to 2003 and compared the release date to breed registrations. The answer seems to be: with the exception of box office flops, yes.

Given that many dog movies are made for kids, I’d be interested in the mediating role of parenthood. Companies that make children’s products like sugary cereal know that they can get the parent to buy their product if the kid is annoying enough about it. So, they market to children directly. I’d love to see if people with and without small children were equally affected by the breed of dog in this year’s movie.

The researchers method of popularity, moreover, was registration with the American Kennel Club. Pure bred dogs are expensive. So, I wonder if the power of these trends varies by social class. If a family can’t afford a “Beethoven,” they may be more likely to just adopt a mutt from a neighbor’s litter.

In any case, though, this seems like incontrovertible evidence that we’re influenced by mass media. But you already knew everyone else was, didn’t you?
