How living in the city affects social behavior

Recent research and commentators have suggested that cities are greener and more innovative. This post from The Infrastructurist summarizes recent research on another possible outcome of interest for city residents: prosocial behavior.

Using census data, Samuel Arbesman and Nicholas A. Christakis of Harvard Medical School examined urban populations for their tendencies to display several prosocial behaviors, including voting, organ donation, and political contribution. As they report in the journal Physica A (in press), Arbesman and Christakis believed this positive social behavior would indeed be superlinear, in part to offset the less desirable elements of a city, such as crime:

If larger networks … fostered increases in violence more rapidly than, say, increases in kindness, city growth would be constrained in a fundamental way.

What they found, however, was that prosocial behaviors “do not obey a clear pattern.” People in cities aren’t more likely to vote or to donate a living organ, though they’re much more likely to give a deceased organ or a political contribution. Taken together, these positive behaviors do not scale the same way that innovation and economic growth typically scale within cities. In short, conclude Arbesman and Christakis, “prosocial behavior is not a single category when it comes to understanding urban scaling with respect to population.”

The mixed results harmonize with previous findings. Some studies have found that people in cities are more likely to return a lost letter than those in both suburbs and small towns. Others have found that willingness to trust strangers declines as a region’s population grows.

The unexpected findings might be explained, in part, by which behaviors the researchers chose to define as “prosocial.” Political contributions, particularly the sizable sort found in cities, could rightfully be considered a selfish endeavor, as opposed to a positive social one. (At the same time, it seems likely that Arbesman and Christakis were limited by available data sets.)

These results are interesting for several reasons. First, there are methodological questions: do we have data in which researchers in the city were specifically looking at prosocial behaviors? A common approach to looking at social behavior and networks these days asks respondents to name their five closest friends and then how closely their personal beliefs, behaviors, and attitudes align with the respondent. But if this study is based on Census data, these social network questions are not present. I’m not quite sure why political contributions would not be considered prosocial – participating in the civic process would seem to be part of being prosocial.

Second, these questions about prosocial behavior are not new. Some of the earliest sociologists developed the discipline for exactly these reasons: what would happen to relationships and society with more and more people moving from small, rural communities to large, anonymous cities? Durkheim and Tönnies developed typologies to explain this: mechanical and organic solidarity and gemeinschaft and gesellschaft, respectively. Simmel, in particular, seemed worried about the effect that the city would have on individuals. He talked about how urban individuals would need to develop blasé attitudes in order to cope with all of the commotion and people they would meet. Simmel continued on to ask whether the individual could maintain their individuality amidst the life of the big city.

It would be interesting to look at data over the years about American perceptions about whether city or suburban dwellers are more prosocial (if such data is available). On one hand, the suburbs are supposed to be the place where kids run free and families know each other yet we talk about how people just drive in and out of their garages without ever knowing their neighbors. On the other hand, we see reports all the time about crime and disorder in the city even as we occasionally hear stories of vibrant neighborhood and storefront life. My guess would be that the suburbs win out easily in this battle of perceptions – even as the research data is mixed on whether city or suburban residents actually exhibit more prosocial behavior.

Baby names and growing entropy

In recent years, the percentage of people who give their babies popular names has dropped. In other words, the range of baby names has increased and more people are seeking unique names. One baby name expert explains why sociologists have taken an interest in this trend:

“The more diverse naming styles become, the more we are going to read into somebody’s name,” Wattenberg said. She analyzed baby name statistics from the U.S. Social Security Administration to calculate a measure called Shannon entropy from the field of information theory. This measure is used to describe the information contained in a message – in this case, how much is communicated by the choice of a name…

Wattenberg calculated a sharp rise in name entropy over time. She found that this measure of the information carried by names has risen as much in the past 25 years as it did in the full century before that. (The measure is independent of the number of babies born.)…

“Sociologists love names,” Wattenberg said. “They’re practically the only case of a choice with broad fashion patterns that there’s no commercial influence on. There’s no company out there spending millions to convince you Brayden is a perfect name for your son.” (Studies have shown that movies, celebrities and other cultural trends do have an impact on the popularity of certain names.)

To understand how the meaning communicated through names has evolved, Wattenberg suggests thinking about an office with a dress code requiring all employees to wear gray or blue suits to work every day. Seeing a man dressed in a blue suit in such an environment would tell you very little about that man’s taste or personality.

Compare that to an office with no dress code. Here employees’ sartorial choices vary widely, so the outfit worn by anyone in that office could tell you a fair bit about that person as an individual. In this case, the same blue suit might reveal significant clues about its wearer.

The same goes for names. In an era where there are a lot more choices available, each choice carries more weight.

This sounds like an interesting analysis. And it sounds like Wattenberg is on to something – sociologists in the last few decades are very interested in how people make decisions that involve symbols, values, and meanings. In a name, parents have a fairly unconstrained choice.

While this is interesting, I want to know more:

1. Even if parents have a lot of choice in choosing names, why have they, as a whole, shifted toward a wider range of names? The article suggests it is indicative of individualism – but why choose to be more individualistic with baby names? How has this happened?

2. Do these new names affect the children’s lives? If parents are giving kids more unique names, are there any consequences to this?

3. Have other countries experienced similar trends? Or is this individualistic trend an American phenomenon?

Making art out of sprawl

The Infrastructurist comments on a story about an artist who uses sprawl and suburbia as his subject. The Infrastructurist and the story commentator suggest these images are alienating and ultimately, tragic:

The suburbs are totally self-contained, labyrinthine, and generally terrifying. The Times describes them as “static, crystalline and inorganic. Indeed, some of these streets frame retirement communities: places to move to once you’ve already been what you’ve set out to be.” We couldn’t have said it better ourselves.

I don’t think one has to see these images as tragic. A couple of possible defenses of such images (and the one The Infrastructurist has on the story is a good one):

1. These can be seen as very ordered places. Not ordered in the sense of traditional city grid ordered but they still have a logic. The streets may be more winding but these communities seem to be centered around retail centers or parks. They may even have their own kind of beauty.

2. If one already thinks sprawl is bad, then viewing these overhead shots may just be throwing fuel on the fire. However, these images can be read as the American manifestation of particular social and cultural values: individualism and privacy as built in single-family homes and suburban streets for our cars. In America, the particular expression of these values may be best exhibited in suburbs. There are other ways suburbs/sprawl could be structured to still support those values – or perhaps these commentators would suggest these values themselves should just be done away with. But that is not a problem with these images; it is an underlying issue with sprawl and suburbs.

Risk of flying in different countries

A new study suggests flying is more dangerous in the developing world compared to the Western, industrialized world:

Arnold Barnett, a professor at the Massachusetts Institute of Technology’s Sloan School of Management and a researcher on aviation safety, calculated that the odds of dying on a scheduled flight in first world countries such as Canada and Japan are one in 14 million.

But he found that flying in emerging nations such as India and Brazil leads to a one in 2 million chance of death per flight. Lesser developed countries, such as many found in Africa and in Latin America, were found to have a crash rate of one in 800,000.

Overall, Barnett says the data suggests airplane safety around the world is improving. Still, these figures could be frightening to some.

Barnett argues this issues in developing countries might be brought on “individualism and deference to authority.” I recall reading something similar recently that said there were more crashes and issues in an Asian country (perhaps South Korea?) because subordinates (anyone on the plane lower than the pilot) felt they could not challenge the pilot’s authority and therefore would not bring up possible problems if they saw them.

But these figures still obscure the fact that flying in an airplane is relatively safer than a number of other, more frequent activities. Check out this graph from the National Safety Council to see the odds of other activities.

Homeowners’ associations and flying flags

An Arizona man is fighting his homeowners’ association over flying a “Don’t Tread On Me Flag.” While this may appear to be a political situation, it is a broader issue: there have been numerous battles over the years between residents and homeowners’ associations over things like flying flags.

On one hand, homeowners’ associations are trying to maintain a certain image in the neighborhood. On the other hand, their rules are extensive and can often appear heavy-handed. However, this Arizona man and many others have a few options that would limit situations like these: don’t move into neighborhoods with such associations (and they are quite common) and know what the restrictions are before purchasing or become involved with the local association and change the rules. As in this situation, two American desires are in conflict: the desire to maintain some local control (and perhaps boost property values) and the desire to be individuals who can express themselves.

Overall, homeowners’ associations are common today in America. According to the Community Associations Institute, there are over 305,000 “association-governed communities” with over 60 million residents.

Plagiarism in the Internet age

The New York Times reports on how getting information from the Internet has changed students’ perceptions about plagiarism:

It is a disconnect that is growing in the Internet age as concepts of intellectual property, copyright and originality are under assault in the unbridled exchange of online information, say educators who study plagiarism.

Digital technology makes copying and pasting easy, of course. But that is the least of it. The Internet may also be redefining how students — who came of age with music file-sharing, Wikipedia and Web-linking — understand the concept of authorship and the singularity of any text or image.

Anthropologist Susan D. Blum studied students at the University of Notre Dame and came to this conclusion regarding attitudes toward authorship:

She contends that undergraduates are less interested in cultivating a unique and authentic identity — as their 1960s counterparts were — than in trying on many different personas, which the Web enables with social networking.

If so, this is an interesting change. It suggests the concept of individualism is changing from one where a person develops unique ideas to one where individuals are creative with existing material.

Perhaps this generation tends to think information on the Internet (and other creative material) is common knowledge. One traditional rule about avoiding plagiarism has to do with common knowledge; if it is widely known, then no citation is needed. What is being confused then is the ease in which the information can be obtained versus whether it has an author. It is true that it is often easy to do an Internet search and find something out. That does not mean that the information is known to all – easy access does not equal common knowledge.

It seems like the best course would be for students to cite all external sources, even if a student thinks it is common knowledge.
