The Danger of Aggregate Displays in Social Software

by Joshua Porter  |   10 Comments

Where is the ethical line drawn when designing interfaces that show popularity?

One of the most important results of people interacting socially online is that we can measure the effect of social influence. A ground-breaking study by Columbia professor Duncan Watts showed how this could be done. (I wrote it up in How Aggregate Displays Change User Behavior) This is one of the most important studies I’ve seen…it clearly shows a relationship between people’s actions and the aggregate information that’s shown to them in the interface.

iTunes Top Songs

For those not familiar with Watts’ study, it showed that when faced with an interface showing what other people did we are definitely influenced by that behavior. If we are shown a list of the most downloaded songs, as in the study, we cannot help but give more weight to those songs downloaded more. We’ll be more likely to download those songs ourselves. This echoes countless studies from social psychology that show how we are affected by our environment.

Dangerous Territory

But one dangerous effect of aggregate displays might not be apparent at first. After we realize that our displays are affecting people, the next question becomes: which aggregate displays do we show and when? This is a question a lot of design teams are grappling with as they build out their social software.

But taking it even further we get into ethical territory. This was made plain to me by a question that someone asked me the other day after we were discussing Watts’ study. They asked: “If people respond to aggregate displays, and change their behavior accordingly as they’ve done in Watts’ study, aren’t those people also in a position to be manipulated?”

Well my first thought was “You rascal. You clever rascal. We’re just beginning to get a handle on how aggregate displays affect behavior and you want to exploit it already!”. But my answer had to be “Yes, people can be manipulated if the data being aggregated isn’t accurate or valid”.

Britney Spears

In subsequent talks I’ve had with people, it has become clear to me that many industries not only manipulate aggregate numbers, but they rely on them to drive business. In the music industry, for example, this is common practice. Studios choose which artists to promote, and suddenly they’re everywhere, their pseudo-popularity created in order to generate actual popularity. This is how we have the Britney Spears’ of the world. She’s a talented singer, of course, but she’s not that talented. While she might be in the top 1% of the population when it comes to singers, her talent is not proportional to the marketing and advertising budgets and revenue that she generates, which is in the top .0001%. (FYI: I made these figures up) Britney is a popular phenomenon, but its impossible to tell how much of her popularity is actual fan support and how much is artificially generated.

So there’s a distinction we can make between actual popularity (which has social influence) and artificial popularity (which also has social influence). The first is driven by actually being a fan of someone. The second is driven by bordering-on-unethical advertising.

It is easy to imagine how this distinction might get unethical in a hurry. Imagine, for example, a list of “Most Popular” music wasn’t really the most popular. Maybe someone paid someone else to show their music on the list. Instead of the most popular, it was the most paid for. This is where real danger comes in. We’re starting to see ways of influencing people’s behavior online…but where do we draw the line?

Some people don’t even like actual popularity, as they are aware of its influence and don’t like the rich-get-richer effect, so to speak. But to me actual popularity is fine, for the most part as long as it’s real. If people are passionate about Britney Spears then it’s OK they influence others…they should be able to spread their passion via word-of-mouth. But when that excitement is artificial, then, well, it’s just not telling the truth…

u write,

“So there’s a distinction we can make between actual popularity (which has social influence) and artificial popularity (which also has social influence). The first is driven by actually being a fan of someone. The second is driven by bordering-on-unethical advertising.”

i dont think u can make such a simple distinction as there are elements of each in the other which interelate in a complex fashion to determine popularity. soros would call it a reflexive process…

This is really important stuff.

Are there any laws about this? Enforcement? Do music download sites state anywhere how they calculate “Top Songs.” Are there any laws that would require such disclosure?

Trust and ethics relate to user interface because people will behave differently when they are in safe versus dangerous environments.

Unethical players, once revealed, can have the effect of changing behavior broadly (e.g. people’s fears of opening email messages with file attachments) thus requiring designers to change user interfaces that may have otherwise been really great.

The conclusion I remember from that study was that social influence can account for huge differences even among indistinguishable competitors (e.g. Britney Spears and, say, Mandy Moore). The differences were at least partly random, making it impossible to predict who/what will become popular.

Of course, manipulation can still play a role. The great thing about luck is that it breaks both ways. For every Britney Spears there is (hopefully) some schlub that got a big push but didn’t get popular.

You should check out Fooled by Randomness and The Black Swan for a good discussion of luck. The study by Watts et al. is a real-world version of the Monte Carlo runs the author talks about in FbR.

If anyone who gets big bucks promotion is succeeding through unethical manipulation, then you have to include whoever gets elected President in the US in that category. It costs something like 100 million to get that job.

We’re all most likely to reach for whatever ‘everyone’ is watching or listening to, for many reasons, but we all still have the option of deciding whether we personally like it or not. With popularity, it’s no different than wanting to be invited to party with the coolest kids in school, whoever they are. There are plenty of adults acting the same way. It’s a personal decision whether to continue that reactive behavior or not.

If you’re marketing any product, you’re going to tell us about how everyone loves it. Truth? Wishful thinking? Manipulation? Is it manipulative to present your business as successful, with lots of happy customers, to prospective clients?

Vera, I think there is a difference between generic forms of self-promotion and tools which purport to report on popularity based on real data.

Part of the power of a database driven Internet is the ability to track data dynamically presenting users with real-time information. If it turns out that most of the data coming from such tools has been highly manipulated by unethical practices — then significant usefulness/functionality has been robbed from the collective Internet community by people making unethical decisions.

I’m not talking about the spammer types who can be expected to make unethical decisions. To whatever degree law enforcement can hunt them down, all the better.

I’m talking about reputable businesses and publicly traded companies who may exploit a lack of laws or a lack of enforcement to justify unethical behavior.

We can’t let the spammer types of the world drive Internet culture.

Shai, thank you and I do understand the distinction.

I don’t see the data as having any particular value(s) in itself when disassociated from the collectors of it, from their intent in ammassing it and in presenting it. The data are now in our machines and in the ‘cloud’, but this does not invest any meaning that didn’t exist when it was mostly on paper.

The ethical issues inherent in our interaction with the offerings of web 2.0 developers are important. Believing this is why I read this post carefully and took time to comment. It concerns me a great deal that so many millions of people are out here playing with all the toys, scattering their personal information everywhere, and taking little or no notice of who is capturing that information or what exactly is being done with it now or will be done with it in the future. I also believe that the data itself and the cool things software allows us to do with it are sometimes an obstacle to our remembering that all of it doesn’t exist in a vacuum where there are no people and therefore no personal responsibility.

Did you see Britney perform at the VMA’s the other day? I’d say that she deserves every by it of popularity she gets? NOT.

Great post, Josh. This is stuff that needs to be discussed out in the open. We have an opportunity to break way out of the “top 40″ mentality and really use systems to promote “the best” of what’s out there by real people. Of course, there’ll be spamming and scamming, but if we can build systems that allow us to communicate with the people we already trust to filter UP the best, we’ll be in good shape.

That brings me to remember the Starbucks phenomenon in Asia. There was not a single advertisement that was made about Starbucks. Then all of a sudden (especially in Manila), Starbucks outlets started to mushroom. The reason of its popularity? All was word-of-mouth. No print advertising and not even a single tv commercial.

WHAT IS SOCIAL DESIGN?

Social design is design that focuses on the social lives of users. It deals with the activities, behaviors, and motivations of people who work and play together through software interfaces. It is built on the observation that many of the decisions we make are greatly affected by those we surround ourselves with in our social lives: our family, friends, and colleagues. Exploring our motivations and how to design interfaces to support them is what the Bokardo blog is all about.
