Battening down the Facebook privacy hatches

Posted on by

The Pew Internet & American Life Project released a new study yesterday that suggests Facebook users are paying more attention to their privacy settings, meaning they are editing comments and photos more and being more selective about their friendships:

The report released Friday by the Pew Internet & American Life Project found that people are managing their privacy settings and their online reputation more often than they did two years earlier. For example, 44 percent of respondents said in 2011 that they deleted comments from their profile on a social networking site. Only 36 percent said the same thing in 2009…

Along those lines is “profile pruning,” which Pew reports is on the rise. Nearly two-thirds of people on social networks said last year that they had deleted friends, up from 56 percent in 2009. And more people are removing their names from photos than two years ago. This practice is especially common on Facebook, where users can add names of their friends to photos they upload…

Women are much more likely than men to restrict their profiles. Pew found that 67 percent of women set their profiles so that only their “friends” can see it. Only 48 percent of men did the same…

Possibly proving that with age comes wisdom, young adults were more likely to post something regrettable than their older counterparts. Fifteen percent of social network users aged 18 to 29 said they have posted something regrettable. Only 5 percent of people over 50 said the same thing.

Several thoughts about this:

1. This isn’t a huge trend: for both deleting comments and friends, a little less than 10% more users did this than two years ago. If this is a long-term trend that keeps going up 10% every few years, this would be especially noteworthy.

2. This is still a low number of people who say they “posted something regrettable.” These figures seem to suggest that many users are ahead of the game here: they are making sure they are being presented in a good light before it could turn into something regrettable. These figures go against a common media image that social media users regularly do crazy things, are always at risk, or don’t know what they are doing.

3. Is privacy the best word to describe all of this? I wonder if we could call this behavior “selective interaction” as it is more about limiting the display of information to certain people rather than hiding information from everyone. If people truly wanted online privacy, they wouldn’t have a Facebook profile in the first place.

4. The removal of friends is interesting. I wonder if this is more of a function of how long one has had Facebook (tied to realizing that one doesn’t really interact with that many people and all of those friends don’t show up in your news feed even if they are updating their information) or changes in life stages (once one leaves high school or college, does one need to remain friends with all of those people you once ran into or thought you might interact with?).

Sociology grad student: “the Internet is a sociologist’s playground”

Posted on by

A sociology graduate student makes an interesting claim: “the Internet is a sociologist’s playground“:

The Internet is a sociologist’s playground, says Scott Golder, a graduate student in sociology at Cornell University. Although sociologists have wanted to study entire societies in fine-grained detail for nearly a century, they have had to rely primarily upon large-scale surveys (which are costly and logistically challenging) or interviews and observations (which provide rich detail, but for small numbers of subjects). Golder hopes that data from the social Web will provide opportunities to observe the detailed activities of millions of people, and he is working to bring that vision to fruition.  The same techniques that make the Web run—providing targeted advertisements and filtering spam—can also provide insights into social life. For example, he has used Twitter archives to examine how people’s moods vary over time, as well as how network structure predicts friendship choices. Golder came to sociology by way of computer science, studying language use in online communities and using the Web as a tool for collecting linguistic data. After completing a B.A. at Harvard and an M.S. at the MIT Media Lab, he spent several years in an industrial research lab before beginning his Ph.D. in sociology at Cornell.

I would think that having a background in computer science would be a big plus for a sociologist today. Lots of people want to study social networking sites like Facebook and work with the data available online. But I wonder if there still aren’t a few issues to overcome before we can really tap this information:

1. Do companies that have a lot of this data, places like Google and Facebook, want to open it up to researchers or would they prefer to keep the data in-house in order to make money?

2. How will Internet users respond to the interest researchers have in studying their online behavior if they are often not thrilled about being tracked by companies?

3. Has the sampling issue been resolved? In other words, one of the problems with web surveys or working with certain websites is that theses users are not representative of the total US population. So while internet activity has increased among the population as a whole, isn’t internet usage, particularly among those who use it most frequently, still skewed in certain directions?

4. Just how much does online activity reveal about offline activity? Do the two worlds overlap so much that this is not an issue or are there important things that you can’t uncover through online activity?

I would think some of these issues could be resolved and the sociologists who can really tap this growing realm will have a valuable head start.

What happens when Tim Pawlenty comes to your sociology class

Posted on by

Courtesy of modern technology, you could have been following a live Twitter stream chronicling what happens when former Minnesota governor and former Republican presidential candidate Tim Pawlenty visits a sociology class at the University of Kansas:

“23 minutes later and I have no idea what he’s talking about,” tweeted Ray. “Freedom, drugs, a kickass pool, meatpacking, MLK.”

It sounded interesting, so I called Ray for an after-action report. The room, he said, was somewhat full and somewhat interested.

“A few hundred students are enrolled in class,” he said, “but maybe a hundred show up. I figure that a lot of the people in the class are freshmen who are just taking it to take it. They probably know Romney, they know Santorum, but Pawlenty dropped out so early that they might not know him.”

But what did the great man say? “Somebody asked him what he thought about Santorum’s victories yesterday,” remembered Gray. “He congratulated him, but he brought up the fact that John McCain lost 19 states and still won the nomination.” Gray paused. “It sounded like a backhanded compliment. And he referred to Minnesota as one of the smaller states, in terms of political power.”

A few quick thoughts:

1. Should we trust a single student’s report in a large 100-level lecture class where roughly half the students don’t attend? I always find it interesting to hear what students remember or find noteworthy.

2. Politicians are now tracked at almost every turn.

3. What exactly does Tim Pawlenty know about sociology? The class is titled “American Identity”…was Pawlenty talking about what he thinks this identity is? I would be really curious to hear (1) what Pawlenty thinks sociology is and (2) whether he thinks sociology has any value.

4. It sounds like Pawlenty was on campus to talk about how the still-to-be determined candidate for President will run a campaign and govern.

Why “Your Facebook friends have more friends than you”

Posted on by

Here is an overview of an interesting quirk on Facebook: your Facebook friend likely has more friends than you do.

It’s just the digital reflection of what’s known to sociologists as the “friendship paradox.” In 1991, sociologist Scott Feld found that, generally speaking, any person’s friends tend to be more popular than they are. The reason, he said, is fairly simple: people are more likely to be friends with someone who has more friends than someone who has fewer friends.

This is true on Facebook as well, the study found. A small number of people are isolated and don’t appear on many lists, but popular people show up again and again.

Another interesting result of the study finds that Facebook users tend to get more messages, friend requests, likes and photo tags than they give, pointing to the existence of a few Facebook “power-users” driving the site’s activity.

Keith Hampton, a professor at Rutgers University and the lead author of the report, said that power users make up around 20-30 percent of Facebook’s users, and that there are three specialties within these power users. Some users send a lot of friend requests, while others most frequently “like” posts and pictures. A third kind of power user tends to make a lot of photo tags.

If you put this in social network terms, there are certain people who are nodes in the Facebook network. These nodes have more friends and are centers of information, comments, pictures, likes on Facebook, between different groups and users.

If we know this is how the world works, you could imagine how this information could be put to use. Perhaps Facebook puts information from these nodes more often in your news feeds. Perhaps marketers hope to specifically target these people as they can have a wide reach. Perhaps other users could look to connect with these nodes, knowing that these people could help them get to information (like jobs? social events?) that a less connected user could not.

I was thinking about this as I was trying to explain network behavior to some students in class recently. Are users of Facebook aware of where they fall within their networks, meaning are they nodes themselves or far from the center of activity? If they are aware of this, does this change their behavior? Would it be beneficial for Facebook to show users where they fall in their network with the chance that it might boost their online activity levels?

All those new Facebook millionaries won’t be buying McMansions

Posted on by

As Facebook prepares its IPO, you might not have considered how it would affect the real estate market in Silicon Valley:

Typically clients pay cash for the homes, he said, which can range anywhere from 4,000 to 15,000 square feet (372 to 1,393 square meters) depending on the size of the family.

Real estate agent Dawn Thomas said she is already seeing home prices rise in areas surrounding Facebook’s Menlo Park headquarters and expects that to continue…

Thomas described her tech-savvy homebuyers as “very, very green-minded” and in search of smaller, tech-equipped, energy-efficient homes with high-end amenities.

“They don’t want ‘McMansions,'” she said, referring to super-sized houses that can gobble up energy.

The implication: the young and wealthy wouldn’t be caught dead buying a home that could be considered a McMansion. If the home is indeed big, and I would say 4,000 square feet is McMansion territory and 15,000 square feet is a just a plain mansion, it has to be green and energy-efficient. Is this the same argument that Gisele Bunchen tried to make recently?

This makes me think that we might need a new term to describe an abnormally large home that is intentionally not a McMansion. A “green home” or “eco-home” doesn’t cut it because these homes are still much larger than the average size of the new American home (around 2,400 square feet). A “greenwashed mansion” but be more accurate but I don’t think these tech-savvy buyers would like the connotations of this term either. Playing off the “Not So Big House,” how about the “not so polluting house”?

College student survives 90 day “Amish Project” without technology

Posted on by

This is a news story that could only be written in our times: a University of Wisconsin-Madison student voluntarily unplugged from all media for 90 days and lived to tell about it. Here is a quick description of his “Amish Project”:

From October to December, he unplugged from social media, email, texts, and cell phones because he felt that we spend more quality time with gadgets and keyboards than we do with the people we really care about.

During his social experiment, he found that some people he counted among his close friends really weren’t that close after all. He also discovered that taking a break from his relationship with social media and really paying attention to the people around him can revive real-life romance.

And a few short thoughts from the student about his experiences:

[on getting started] I mean, I struggle with that because everyone wants to know about it, and wants to know how different it is. It’s hard, because I was just going to turn off my phone at first. That was the thing that bothered me most, but I realized that if I turned off the phone, people were just going to email me all the time or send me a million Facebook messages. It’s kind of a hard thing, because we’re getting to the point where if you’re not responding to people’s text messages within an hour of when they send them, or within a day for emails, it’s just socially unacceptable. It’s been hard for me since I’ve been back. I’ve been bad with my phone and people are, like, “What the hell? I text messaged you…” So I haven’t been up to social standards in terms of responding and people don’t really understand that, I guess…

[on finishing the project and returning to technology] It’s definitely different, but I catch myself doing exactly what I hated. Someone is talking to me and I’m half-listening and reading a text under the table. For me, it’s trying to be more aware of it. It kind of evolved from being about technology to more of just living in the moment. I think that’s what my biggest thing is: There’s not so much chasing for me now. I’m here now, and let’s just enjoy this. You can be comfortable with yourself and not have to go to the crutch of your phone. For me, that’s more what I will take away from this.

A few thoughts:

1. The author concludes that this means “texts and Facebook wall posts can serve as an attractive veneer making relationships seem more genuine than they really are.” I wonder how many people feel this way and if many do, do they simply keep going along out of habit or because of social pressure?

2. It seems like a lot of things that there possible for this student without technology might be much more difficult for the average adult. At college, it is much easier to find people, run into others, and pass notes, even on a big campus like UW-Madison. Could the average adult who lives alone and commutes to work make this work? Perhaps the key here is living near or very close to people one cares about.

3. What if it becomes “cool” to unplug from technology or turns into a status symbol rather than a reasoned choice about paying more attention to the people that mater?

4. I find the set-up to stories like these to be humorous: how in the world could people have survived without the technology we have today?!? Somehow they managed. The comparison here to the Amish is funny as well – there is a whole lifestyle associated with this that this college student isn’t truly considering.

5. This story presents a contrast between “authentic/real” relationships versus “superficial” relationships. Is it really that easy to categorize relationships? Research suggests most people use technology like Facebook to try to maintain a connection between people they already know – is that necessarily so bad? Perhaps it does detract from the present but it also makes us more aware of our broader social networks.

Overblown concern about Google “replacing” or “destroying” our memory

Posted on by

The headlines read: “Google ousts brain,” “Google replaces the brain,” “Here’s how Google search is destroying our memory.” These are all based on a new study:

The Internet is becoming our main source of memory instead of our own brains, a study has concluded.

In the age of Google, our minds are adapting so that we are experts at knowing where to find information even though we don’t recall what it is.

The researchers found that when we want to know something we use the Internet as an ‘external memory’ just as computers use an external hard drive…

‘The Internet has become a primary form of external or transactive memory, where information is stored collectively outside ourselves.’

This an example of “distributed cognition,” the idea that humans use other sources to extend their brain’s capacity. In this case, memory space in the brain may be freed up by relying on Google and computers to store certain information. Instead of “replacing” the brain, Google is extending the brain and helping humans offload certain information that can helpfully be stored elsewhere. Google isn’t the first technology that allows this; so does the printed page. Rather than storing a bunch of arcane and typically unhelpful information in our head, we could look up basic information in a reference book.

Perhaps people are more concerned about Google itself and the idea that a corporation, an organization more interested in profit than our well-being, may be behind changes in our brain.

Just the beginning of using social media to study political and social beliefs and behaviors

Posted on by

As the 2012 election nears, here is an overview of where we stand in using social media to understand people’s political and social beliefs and behaviors:

Marc A. Smith, a sociologist who studies online communities and founded the Silicon Valley-based Social Media Research Foundation, said “we are in the Model T Ford era of information systems” and analyzing their content.

Scott Keeter, the president of the American Assn. of Public Opinion Research, said that members of the professional organization and journalists should “proceed with a degree of humility” in deciding what social media can tell us about political campaigns. “Until we have more experience with real world outcomes, it’s hard to know the meaning of what we have captured from social media,” said Keeter, director of survey research at the Washington-based Pew Research Center for the People & the Press.

Much of the debate followed a Jan. 12 article by Politico, the online news site, which reported that it had partnered with Facebook to examine all “posting, sharing and linking about candidates” from Dec. 12 to Jan. 10. The arrangement was a first not only in that Facebook delved into both public and private messages but also used computer analysis to “identify positive and negative emotion in text.” (The company stressed that while computers draw an aggregate view of user sentiment, human beings do not monitor individual messages.)

Facebook said it employed a “well-validated software tool used frequently in social psychological research.” But Smith said he was “highly skeptical” of some of the precise findings in the Facebook analysis. He added that the intellectual disciplines focused on deciphering texts — natural language processing and computational linguistics — “are very deep and can do remarkable things, but they don’t necessarily have the ability to predict the next president of the United States of America.”

A few thoughts:

1. I like the urge to be cautious: too many news outlets jump on relatively small and meaningless events in the realm of social media and try to draw big conclusions. For example, the size of a Facebook group doesn’t say much. Similarly, I am still surprised by the number of media outlets that show the results of unofficial (and often low-count) poll results (though they now say they are not scientific results).

2. While being cautious is good now, it does suggest that this is a burgeoning area with lots of potential. The researchers who develop good methodologies and get access to specific or unique data will get a lot of attention. I wonder how much companies like Facebook really want to contribute to social science research as opposed to using their data to make money.

3. The counts of positive and negative feelings seem fairly unhelpful to me. For example, what does tracking the emotions of the world through tweets really tell us? Another example from the offline realm: “how the Bible feels.” This is where we need more than just descriptive research.

The real question to ask about the iBooks 2, textbook killer: will it help students learn?

Posted on by

There is a lot of buzz about the iBooks 2 but I have a simple question: will students learn more using it? In one description of the new program, this isn’t really covered:

Yet, the iPad offers a big opportunity for students to get excited about learning again. The iPad has already demonstrated it can help children with learning disabilities make leaps in bounds in their development, and schools have already invested heavily in Apple’s tablet. Roughly 1.5 million iPads are currently in use in educational institutions.

Schiller said that the problem with textbooks is not the content, which is “amazing,” but the weight of the physical book. They need to last five or six years when they’re written, and they’re not very durable or interactive. Searching is also difficult.

At that point, Schiller introduced iBooks 2, which has a new textbook experience for the iPad. The first demonstration showed what it’s like to open a biology textbook, and see an intro movie playing right before you even get to the book’s contents. When you get to the book itself, images are large and beautiful, and thumbnails accompany the text. To make searching easier, all users need to do is tap on a word and they go straight to the glossary and index section in the back of the book…

Jobs had long hoped to bring sweeping changes to higher education for much of his life. When he left Apple and launched NeXT in 1986, Jobs wanted the company’s first computer — a distinctive all-black magnesium cube — to be designed specifically for higher education establishments and what Jobs called “aggressive end users.”…

“‘The process by which states certify texbooks is corrupt,’ he said. ‘But if we can make the textbooks free, and they come with the iPad, then they don’t have to be certified. The crappy economy at the state level will last for a decade, and we can give them an opportunity to circumvent the whole process and save money.'”

Based on this article, I see five things that are good about iBooks 2: it will excite students, it is lighter to use so don’t have to carry so much weight around, it will be cheaper for everyone in the long run, there are some cool features like searching and embedded videos, and it could make Apple a lot of money (and presumably traditional textbook publishers will lose money unless they adapt?).

But, we have been told for decades that better technology in the classroom, computers, laptops, the Internet, etc., will lead to improvements in learning and test scores. Isn’t this how iBooks 2 should be measured? It is good if kids are excited about learning again but will this tool actually help them learn more? The technology may be better and cheaper in the long run but this doesn’t necessarily mean it will lead to improvements in the education system.

I wouldn’t go so far as to say that iPads or iBooks 2 can’t lead to better learning but I would want to know a lot more about its effect on educational outcomes before simply adopting the technology.
