Here’s how cities say “stay out” with anti-homeless design, part of the wider phenomenon of hostile architecture.

If it walks like eugenics and quacks like eugenics… Dozens of female inmates were sterilized without consent in California, and a Virginia man’s plea bargain included a promise to get a vasectomy.

Up to 75 CDC researchers may have been exposed to live anthrax.

The first description of fellatio in male bears has been published. The study attributes the behaviour (observed in captive bears) to an absence of maternal suckling, but its claim that mammals rarely engage in non-copulative sexual behaviours suggests that their lit review was incomplete.

Scientists weigh in on the commonly misused terms that drive them crazy. Bonus: the pseudoscientific claims that drive us crazy. And speaking of pseudoscience, Dr. Oz admitted before a senate committee that the weight-loss ingredients he endorses aren’t miraculous, but he defended his right to employ “flowery language.”

Some of Wyoming’s math & science professors, as well as some of its churches, support reformed educational standards that include climate change and evolution, while others criticize them for requiring “a materialistic explanation for any phenomenon addressed by science” or for leading to negative economic consequences for the energy-exporting state if global warming is taught in schools.

“Suicidal thoughts” warnings on antidepressants may have indirectly led to increased suicide attempts.

Whooping cough, a vaccine-preventable bacterial infection that can be fatal in infants, is now an epidemic in California. At least one sufferer of last year’s outbreak thinks she knows who to blame.

Headlines far and wide proclaimed that a computer program has “passed the Turing test.” What they really mean is that by pretending to be Eugene Goostman, a teenager from the Ukraine with a poor grasp of English, the program won a University of Reading contest by convincing 1 in 3 judges that it was a human being, satisfying Turing’s predictions for the capabilities of artificial intelligence for the year 2000. So perhaps the resulting skepticism is warranted.

The Ultimate Filter Bubble

Mike Thicke

As if we needed reasons to be more worried about Google taking over the world, a new study suggests that it could have an enormous impact on elections merely by manipulating search results. Researchers Robert Epstein and Ronald Robertson of the American Institute of Behavioral Research and Technology found that they could “sway the voting preferences of undecided voters by 15% or more” merely by biasing search results presented to research subjects. This is interesting—and scary—in its own respect, but it also has connections to some of my earlier posts about Internet filter bubbles and what I’ve called the “Internet Observer Effect“.

These are not the voters you’re looking for

Mike Thicke

People across the political spectrum have long recognized that our democratic system disenfranchises the unborn. Those on the left tend to worry that those alive today are pillaging natural resources from future generations. Those on the right tend to worry that excessive public spending will force our children or grandchildren into economic slavery. Either way, people in the future will be forced to live with the consequences of our present decisions, but they have no say in those decisions (though Greg Lusk has problematized this reasoning).

How to solve this problem? Philosopher Thomas Wells proposes a direct solution: give voting powers to “trustee” organizations “such as charitable foundations, environmentalist advocacy groups or non-partisan think tanks.” These organizations would have a block of votes equivalent to something like 10% of the overall electorate. If there are 10 million eligible voters in an election, we would assign 1 million votes to these organizations. Wells’s idea is that these organizations would vote with the best interests of the future in mind. Not only could they affect the results of elections, but Wells predicts they would shape the political conversation as politicians tailor their policies to appeal to this powerful voting block.

Alex Tabarrok over at Marginal Revolution finds Wells’s proposal “laughable”. He sees Wells’s proposal for a select group of trustees as merely replicating Wells’s own view of how the future ought to look. Instead, Taborrok proposes the economist’s universal solution: the market. Specifically, prediction markets. While I share some of Taborrok’s skepticism of Wells’s proposal, I find Taborrok’s proposal even less realistic. I shall focus my critique on two problems: an epistemic problem and a relevance problem.

Weekly Roundup – Supersized

Welcome to a super sized weekly roundup! I’m on vacation next week; here’s a double helping of stories to keep you sated until next time.

A new, disputed study from Cornell’s Food and Brand Lab suggests that  eating chicken on the bone increased aggression in children compared with eating pre-cut pieces. It sounds like fun research: the drumstick-eaters “were also more likely leave the 9-foot circle radius, jump around, and stand on the picnic tables without permission.” The Cornell Lab, home of the endless soup bowl, studies the social and environmental factors influencing food consumption. 

A climate scientist explains how she explains climate change to her fellow evangelical Christians: why should they care about a changing climate?

Don’t panic, but Mount St. Helens’ magma is repressurizing.

“Selfitis,” or the obsessive taking and posting of photos of oneself, isn’t a new mental disorder, but many of us were fooled by the satirical story claiming that the American Psychiatric Association coined the new disease category.

Ketchup, perhaps the tastiest of the non-Newtonian fluids, is notoriously hard to pour from a glass bottle. NPR goes into the details of the condiment’s physics that were illustrated in George Zaidan’s TED talk. If manufacturers ever incorporate LiquiGlide, the food-safe, potentially profit-eating surface coating, into their containers, it will be a whole new ballgame.

Coke and Pepsi have bowed to public pressure and removed brominated vegetable oil (BVO) from their soft drinks. Popular Science explains what BVO is and what it was doing in soda in the first place.

We may know the secret of how the pyramids were built.

Gender, science, and bad reporting: A study in Nature [paywall] revealing genes on the Y chromosome that fulfill the same function as those on the X chromosome is publicized as demonstrating sexual difference, the very opposite of the study’s findings. What’s behind this “sex difference paradigm?” [via Feminist Philosophers]. Also, duck penises are all well and good, but what about duck vaginas? Ed Yong at Nat Geo’s blog Not Exactly Rocket Science explores the combination of biological and social factors that influence the differential treatment of animals’ sex organs.

Do sports perpetuate or help fight discrimination?

I look at an article from sports sociology that suggests descriptions of athletes might perpetuate inaccurate stereotypes.

Like many other people, I was shocked to hear the alleged tape recording of Donald Sterling saying that his girlfriend should not take photographs with black people, or bring them to basketball games (but she can bring them to bed). I don’t follow sports very closely anymore; I didn’t know that Sterling, at least according to the Guardian, made millions as a landlord through racist housing policies. Maybe we should have seen this coming.

Some have argued that the emphasis on Sterling’s comments obscured the larger, more

“In 1997, the 50th anniversary of Jackie Robinson joining Major League Baseball, his old team the Dodgers had the exact same number of American-born Blacks on the opening day roster as they did in 1947: one.” J. R. Woodward (2004)

harmful, actions that he has taken (the Guardian suggests this, as does the link below).  In particular, they point to the housing discrimination he was accused of perpetrating as an owner of 100’s of properties in the Los Angeles area. Housing discrimination is terrible, and (like all forms of discrimination) should not be tolerated.

However, many of these arguments that suggest housing discrimination is “actually harmful” imply that Sterling’s other actions were largely inconsequential. I thought that, perhaps, this position might stem from a belief that in the realm of sport, discrimination was not significant. In fact, it might even be thought that sports are a way for those frequently discriminated against to get ahead, since, on the face of it, it would seem that on-field performance would be the dominant driver of athletic success. There are obvious reasons to resist at least the first part of this description, for example, racism against black soccer players in Spain is so pervasive that the players can plan their responses in advance. 

Still, I wondered, do sports perpetuate or help fight discrimination? There is obviously no cut and dry answer to this question. It is too broad a question to be answered directly: there are many different sports, and too many ways of thinking about discrimination for the question to be taken seriously. However, in thinking about the question, I took a look at the academic literature on sociology of sport. I found it surprising that this literature is not more heavily cited in recent discussions of racism in sports.

Here I’m going to share excerpts from a paper entitled “Professional Football Scouts: An Investigation of Racial Stacking” by J. R. Woodward (2004). The study covered in the article analyzes draft guides that describe the suitability of college athletes for the NFL draft, paying particular attention to the descriptions of the perceived physical and mental capabilities of white and African American players. I quote this paper it because the study is interesting, but also because it has a fairly detailed literature review with some interesting studies. Given that it seems the sports media perpetuates the messages discussed in this study from 2010, and broadcasts to millions of people, I would guess the messages we receive about sports and athletes portray more bias than we immediately realize.

Literature Review

“Coakley (1998) notes, there are roughly 20 times more African American physicians and lawyers than top professional athletes; nor have most sports truly integrated to allow for equal participation and rewards between the races. In 1997, the 50th anniversary of Jackie Robinson joining Major League Baseball, his old team the Dodgers had the exact same number of American-born Blacks on the opening day roster as they did in 1947: one.”

“Whites dominate most sports at the collegiate and high school level; football, basketball, track, and baseball—sports where Whites are underrepresented—make up only 4 out of at least 40 sports played competitively.”

“The belief that sport has been a source of upward mobility for African Americans has been rebutted in previous research and is not the object of this project (see Sailes, 1998; and Smith, 1993, 1995). What is of interest, however, is the tenacity of this view. Personal beliefs about race and sport are often solidified when society at large seems to share and reinforce these beliefs, regard- less of their veracity.”

“One manifestation of our “race logic” (how we come to understand racial phenomena in society) is the link between race and athletics, principally the belief in African American athletic superiority. Unfortunately, concomitant with this view has been the conviction of mental inferiority; i.e., the “dumb jock” stereotype (Hoberman, 1997; Eitzen, 1999). American history is replete with academic, intellectual, and social discussions of the primitive nature of Blacks, whose supposed strength, power, and sexual aggression made them appear almost animalistic, an assertion strengthened by their perceived lack of innate cognitive abilities (Mead, 1985).”

“Racial ideology, then, was situated in a particular, disparaging view of African Americans as physical, not mental beings. Athletics was just one of many endeavors in which this view was manifested (Coakley, 1998).”

“Racial stacking is the over- or underrepresentation of players of certain races in particular positions in team sports (Coakley, 1998). For example, quarterbacks in football and catchers in baseball have traditionally been White, whereas Black players are more often found playing in the outfield in baseball and as running backs or wide receivers in football.”

“Loy and McElvogue (1970) presented the first study on racial stacking by examining the racial makeup of baseball and football in America. Their findings suggested that White players are more likely to be found in what they termed central positions (i.e., discrimination is most likely to occur at central positions in any social organization, where the most interaction occurs).”

The Study

“In this study, an assessment was made to determine whether scouting reports of college quarterbacks, centers, inside linebackers, and tight ends relied on mental descriptors of White players and physical descriptors of African American players. At a basic level, scouts are individuals raised in contemporary U.S. society with all the implied racial beliefs. Because physical and mental abilities relative to football can be extremely subjective, it follows that descriptions of athletes in various positions would differ for Whites and African Americans, based solely on the ascribed characteristic of race. The first three positions, which were included in the pilot study, are commonly referred to as “thinking positions.” A question for this research, following the dominant U.S. race logic, is whether White players in the thinking positions are described more in terms of their mental attributes and, conversely, whether African American players in these positions are described more in terms of their presumed physical attributes. The fourth position, tight end, is not typically considered a thinking position and will be used, in essence, as a control group.”

“As with the 5-year sample, African American athletes described in the 2003 draft guides (see Table 4) were more likely to be described by pro scouts in physical (â = .298, p < .001) terms relative to Whites, and were less likely to be described in mental terms than were Whites (â = –.599, p < .001; see Table 5).”

“Of primary importance for racial stacking is the way we “interpret actions and relationships” as Coakley (2004) contends. At the most basic level, stacking involves individuals witnessing action and trying to make sense of that action using preconceived notions and racially informed cogni- tive grids. When scouts assess a player’s talents and abilities, they are not doing so in a vacuum, rather, they are filtering this new material through countless layers of conscious and unconscious understandings, both real and perceived. Objectivity can, therefore, be very difficult to attain and prior beliefs quite difficult to eradicate.”

That’s not to say that albatross dads don’t occasionally have a dalliance with ladies who aren’t their mates.” Finally, at the Daily Mail, we are treated to “Men really are less likely to say ‘not tonight dear, I have a headache’ than women, new research shows” and “Women lose their libido when they are in pain while men do not.” Top-notch reporting on the research on sex differences in libido response to pain, as long as you keep in mind that the men and women were mice.

Infographic: Americans use more energy in 2013 than in 2012

Greg Lusk

The bad news is that Americans used more energy in 2013 than in 2012.  Unchanged is the fact that US energy efficiency is still terrible. The good news is that 2013 saw  more renewable energy produced!

Each year the Lawrence Livermore Labs releases an energy flow chart, which is a great infographic that displays the origin of US energy, the sectors that use that energy, and the efficiency of each sector. This year’s infographic was recently posted (click on the image to make it larger).

Lawrence Livermore Labs Energy Infographic

Some highlights from the lab’s news release:

  • “Wind energy continued to grow strongly, increasing 18 percent from 1.36 quadrillion BTUs, or quads, in 2012 to 1.6 quads in 2013.”
  • “Natural gas prices rose slightly in 2013, reversing some of the recent shift from coal to gas in the electricity production sector.”
  • “Petroleum use increased in 2013 from the previous year.”
  • “Rejected energy [roughly energy lost to inefficiency] increased to 59 quads in 2013 from 58.1 in 2012, rising in proportion to the total energy consumed.”

What I enjoy about this infographic is that it highlights the rejected energy, which highlights the inefficiency of  US energy use. Transportation, as you can see, produces a lot of rejected energy (probably due to the inefficiency of the combustion engine). If we can’t curb our energy use (which I think we should) then we absolutely need to be doing a better job finding efficiencies.
