The Psychology of Facebook

Of the 20 most popular websites in the world, 13 relate to corporations that have European headquarters in Ireland: Ebay, Google, Yahoo and Facebook. The last three of these corporations have been the source of much commentary on this blog. Facebook (FB) has 1.5 millions users in Ireland and it is competing strongly with Google for web-user time-allocation. The chart below (from comScore/Citi) shows FB's increasing share of web-user time-allocation since 2006. FB has an explicit interest in internet economics and it has been mentioned many times before on this blog: from ambient awareness to the App Economy, FB search data to Mulley Com's study of FB eye-tracking, the choice architecture of FB, the FB Global Happinness Index, and of course, the debate on whether FB-use hurts students' grades.


Earlier this week in the Irish Times, Eoin Burke Kennedy wrote an interesting article about the psychology of FB. "Extroverted people tend to have more friends on Facebook but reveal less about themselves while introverts disclose more personal details but to a smaller group." Extraversion is one of the Big 5 personality traits: often discussed on this blog in the context of non-cognitive ability. Here and here, for example. The Big 5 personality traits have also been discussed on this blog before - in relation to social networking and web-users' choice of email address. Readers who find these topics interesting may want to read about the developing field of cyberpsychology - this subject encompasses all the psychological phenomena that are associated with or affected by emerging technology.

The content of the Irish Times article (mentioned above) is based on work by Dublin Business School psychologist Dr CiarĂ¡n McMahon. "McMahon has conducted an extensive review of the psychological literature on Facebook to better understand what makes it tick". McMahon runs a blog, PsychBook Research, which links to one of his recent presentations: "Facebook and psychology: What we know so far". While the Geary Blog has often mentioned the career opportunities for economists in corporations such as Google, Yahoo, and Microsoft; and opportunities for applied economists in private sector firms such as Netflix, SeatGeek, Yapta, Inon and Nielsen; opportunities for psychologists seem likely in Facebook, and in other Web 2.0 commerce.

WePredict

Using Twitter for macro-level analysis has been discussed on the blog before:
(i) Sample Selection, Twitter's Public Timeline, TweetScan and Quotably
(ii) Twilert (re-launched this month), Summize Labs, Twitter's acquisition of Summize
(iii) Life Analytics: Sentiment on the United States Economy
(iv) The Google-Index of Social Media, and the apparent superiority of Bing for deciphering real-time breaking trends

So it was interesting to read a recent article in the Irish Times about two students who used Twitter to predict that Joe McElderry would win the recent X-Factor competition... before the results were announced. "Ben McRedmond (17) and Patrick O’Doherty (16), two fifth years from Gonzaga College, Dublin demonstrated the power of their social networking analysis system, We Predict, at the BT Young Scientist and Technology Exhibition. It was developed over more than five months and is based on storing and studying a growing database of 24.5 million tweets which hold clues about what people are thinking."

A quick search led me to the WePredict website. The information there states that: "WePredict is a showcase of several technologies we have built: a data mining application, capable of mining data from multiple social networks; and a complex suite of analysis tools for analyzing this data...WePredict's large database of over 22 million status updates growing at 20 a second makes it the largest user survey ever done... using the collective intelligence of the whole internet, a mere 1.5 billion people, we can predict the outcomes of elections, talent shows or who will be the christmas #1 and analyze the public reaction to new legislation or medical epidemics."

An exciting endeavour such as this one reminds me of Hal Varian's famous quote that "the sexy job in the next ten years will be statisticians." A two-minute YouTube clip of Google's Chief Economist is shown below, discussing this very issue.

One Step Closer to Perfect Information

"MySpace and Facebook have both signed deals with Google to allow publicly available status updates to be indexed in real-time by the search giant...Up till now Google had only signed a similar deal with Twitter and was missing agreements with Facebook and MySpace...This means that when somebody searches for a particular topic on Google they will receive real-time updates from a variety of social media sites, as well as the usual list of search results." Full story here.

Openness - "a history of the Internet and its lessons for the future of business, politics, and society

That's the somewhat broad provisional title (though you can suggest your own to the author at his blog, linked above) of Johnny Ryan's new book. Johnny previously wrote ‘Countering Militant Islamist Radicalisation on the Internet: A User Driven Strategy to Recover the Web’ and The Next Leap: Competitive Ireland in the Digital Era, described as "Strategic Report on the Trends of Change in the Digital Sector, and Government Opportunities for Action, Based on the IIEA Digital Sector Stakeholders’ Consultation"

His new book is summarised thus:

The Internet is a centrifugal force, user driven and open. These three characteristics have asserted themselves throughout its history. Understanding them is the key to adapting to the new global commons, a political and media system in flux, and the future of competitive creativity.


Certainly the blog post paints an interesting picture - as well as one of the controversy about the word Openness - itself.

Data on Discussions and Social Networks from the Last 10 Years

Ten years of discussions from the Irish forum site boards.ie are available in SIOC format; more details are available here. The FOAF files link to each other, describing a social network based on the users' buddy lists.

The data in total (over 10 years) is around 9 million documents and takes about 50 gigabytes of disk space - it's all in RDF/XML file format. This resource is supported by Science Foundation Ireland under grant number SFI/02/CE1/I131 at the Digital Enterprise Research Institute (DERI), National University of Ireland, Galway.

The Economics of Attention

Your attention is a scarce resource. In the Information Economy, this is more critical than ever. Before I elaborate on the economics of attention, I want to motivate its importance based on previous posts about scarcity in resources that are not land, labour, capital or enterprise. We've heard about the knowledge economy, information economics and time-allocation. While knowledge, information and time are important, it may be time to turn our attention to, well... attention - the new scarce resource.

To illustrate how economists think about 'non-traditional scarce resources', I'll begin with a discussion on time use (or time-allocation). This resource is the closest in essence to attention (with knowledge and information being more similar in their nature; also, attentive use of time is needed to acquire knowledge and sift through information). Time-allocation is the first-stage decision in various production functions; on top of this comes the application of attention. As time-use has been discussed quite a bit on this blog, it's a good place to start. Here's a paper about student time use and academic performance; here's one about whether the recession is making students study harder.

More recently there was a link to the presentation at Google by Zimbardo and Boyd on time perspectives. In the MetaPsychology review of Zimbardo and Boyd's book, the point is emphasised that time cannot be replenished - in contrast to other goods, such as gold, diamonds, etc. Therefore, you have to be more careful about how to spend your time. Zimbardo and Boyd ask: "Why do we often spend our money more wisely than our time?"

I agree with Michael Daly that the ability to recognise our time perspectives and to switch between perspectives efficiently is important (see a brief summary of the perspectives here). Aaron Swartz suggests that "time perspective” is a concept which Zimbardo has essentially come up with himself, but which he feels (not without some justification) is rather important.

I'm inclined to agree - after reading about and working with the consideration of future consequences scale (CFC) a lot - "time perspective" seems to offer a more comprehensive theory of how we interact with "time". There of course may be scope to use both the CFC and the Zimbardo Time Perspective Inventory in a research project - a recent article by Adams and Nettle in the British Journal of Health Psychology does just that.

In addition to time-allocation and time perspectives, 'attention' plays an important role in how human behaviour produces outcomes. The most illustrative example I can think of is the recent debate on student time use and online social networking. The question that we debated was "does Facebook hurt your grades?". The conclusion offered by Aryn Karpinski (at Ohio State University) is that her research does not suggest that Facebook directly causes lower grades, merely that there's some relationship between the two factors. "Maybe [Facebook users] are just prone to distraction. Maybe they are just procrastinators".

An attempt has been made to replicate the results of Karpinski's research. Eszter Hargittai, associate professor of communication studies at Northwestern University and a fellow this year at Harvard's Berkman Center for Internet & Society, says the following: "We found no evidence that Facebook use correlates with lower academic achievement". More details on this are available here.

The main point I want to make is based on the opening comment in this post: that attention is a scarce resource. While students may allocate their time across activities such as study and online social networking, how much attention are they giving to each activity? Are they so zoned into Facebook that that they can't cope with the Twitter Mania, but when it comes to study is the intensity a lot less? Is designated study time interrupted by SMS text messages, tweets and the like? Or is there just less concentration applied to the activity of study?

On his MindBlog, Derek Bownds states that concentration is the issue of our time(s) (sic). He mentions a NYT article by John Tierney on the science of concentration. A clip from this is below:

"You can lead a miserable life by obsessing on problems. You can drive yourself crazy trying to multi-task and answer every e-mail message instantly...Or you can recognize your brain’s finite capacity for processing information, accentuate the positive and achieve the satisfactions of... the focused life."

With attention and concentration such critical issues in the production functions for study, research and a whole range of activities that feed into the knowledge economy, I have taken a renewed interest in mindfulness - something which Michael has mentioned on the blog. A number of times. Liam also linked to a lecture by Kabat-Zinn on mindfulness - originally presented to staff at Google.

The framework I am most interested in, however, is what this blog post is essentially about - the economics of attention. Attention economics is an approach to the management of information that treats human attention as a scarce commodity, and applies economic theory to solve various information management problems. It's not new - Herbert Simon was perhaps the first person to articulate the concept of attention economics when he wrote:

"...in an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes. What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the overabundance of information sources that might consume it" (Simon 1971, p. 40-41).

Simon noted that many designers of information systems incorrectly represented their design problem as information scarcity rather than attention scarcity, and as a result they built systems that excelled at providing more and more information to people, when what was really needed were systems that excelled at filtering out unimportant or irrelevant information (Simon 1996, p. 143-144). We have such systems now - you can skip the ads on TV if you want! You can also block out email spam.

"Attention economics" today is largely concerned with the problem of getting consumers to engage with advertising (sellers compete for scarce attention). However, it would be worth developing a stream in attention economics that relates to academic production functions, the knowledge economy, health behaviour and well-being. A final thought: we should all be careful with those little drops of dopamine. And bear in mind that business is going to get your attention using style, for style is what competes for our attention amidst the din and deluge of the new media (see Richard A Lanham - The Economics of Attention).

Does Facebook Hurt Your Grades? Can Twitter Make You Smarter? What About YouTube?

Does Facebook hurt your grades? This may be the question that parents everywhere will soon be asking their children. There is the argument that students cannot blame Facebook because if Facebook did not exist, they would find another distraction. However, Facebook users under parental supervision will probably have scant praise for the researchers from Ohio State University who have shown that the majority of students who use Facebook every day are underachieving by as much as an entire grade, compared with those who shun the site. See the story in the Times here.

The researchers discovered that students who spend their time accumulating friends, chatting and “poking” others on the site may devote as little as one hour a week to their academic work. “It is the equivalent of the difference between getting an A and a B,” said one of the researchers, Karpinski. Of course, this does not account for selection bias and unobserved characteristics. Also, the researchers have not yet analysed whether a student’s grades continue to deteriorate the longer he or she spends on Facebook. So the same individuals have not been tracked over time.

A new YouTube offering may take up as much of students' time as a Facebook account, though it may help their grades. "YouTube University" has gathered together all the video channels of the universities and colleges it's partnered with over the years and put them under the YouTube EDU banner. One of the videos (below) is from the University of Minnesoata and is about using Twitter, Wikis and instant messaging in the classroom.

Educational researcher Cynthia Lewis says that the use of social media in the classroom serves two purposes. The first is catching the attention of students and increasing their participation in the classroom. The second is preparing them for communicating in tomorrow's new media landscape. She says that "21st century literacies are all about digital media".





While it may be the case that too much Facebook can hurt your grades, doing the right amount of social networking through online platforms can help your career and is also a lot of fun. Plus, it may help learning in the classroom.
