Why Do People Buy Things They Don't Want Online?Emerging research investigates how online technology can lead to negative group behavior.

The ubiquity of media can influence wide-scale behavior based on false premises, according to researchers.

“Group behavior that encourages us to make decisions based on false beliefs has always existed. However, with the advent of the internet and social media, this kind of behavior is more likely to occur than ever, and on a much larger scale, with possibly severe consequences for the democratic institutions underpinning the information societies we live in,” said Vincent F. Hendricks, Ph.D.

Hendricks is a professor of philosophy at the University of Copenhagen and a co-author of an article titled “Infostorms,” recently published in the journal Metaphilosoph.

In the article, Hendricks and collegues analyze a number of social information processes which are enhanced by modern information technology.

Reserchers cite the curious fact that an old book entitled “Love Letters of Great Men and Women: From the 18th Century to the Present Day,” suddenly climbed the bestseller list, as an example of group behavior set in an online context:

“What generated the huge interest in this long forgotten book was a scene in the movie ‘Sex and the City’ in which the main character Carrie Bradshaw reads a book entitled ‘Love Letters of Great Men’ — which does not exist.

“So, when fans of the movie searched for this book, Amazon’s search engine suggested ‘Love Letters of Great Men and Women’ instead, which made a lot of people buy a book they did not want.

“Then Amazon’s computers started pairing the book with ‘Sex and the City’ merchandise, and the old book sold in great numbers,” Vincent F. Hendricks points out.

“This is known as an ‘informational cascade’ in which otherwise rational individuals base their decisions not only on their own private information, but also on the actions of those who act before them. The point is that, in an online context, this can take on massive proportions and result in actions that miss their intended purpose.”

While buying the wrong book does not have serious consequences for our democratic institutions, it exemplifies, according to Hendricks, what may happen when we give our decision-making power to information technologies and processes.

He also points to other social phenomena such as “group polarization” and “information selection” which do pose threats to democratic discussion when amplified by online media.

“In group polarization, which is well-documented by social psychologists, an entire group may shift to a more radical viewpoint after a discussion even though the individual group members did not subscribe to this view prior to the discussion.”

Hendricks believes this happens for a number of reasons: One is that group members want to represent themselves in a favorable light in the group by adopting a viewpoint slightly more extreme than the perceived mean.

For example, in online forums, this behavior is made even more problematic by the fact that discussions take place in settings where group members are fed only the information that fits their worldview, making the discussion forum an echo chamber where group members only hear their own voices.

Companies such as Google and Facebook have designed algorithms that are intended to filter away irrelevant information — known as information selection — so that we are only served content that fits our clicking history.

According to Hendricks, this is, from a democratic perspective, a problem as you may never in your online life encounter views or arguments that contradict your worldview.

“If we value democratic discussion and deliberation, we should apply rigorous analysis, from a variety of disciplines, to the workings of these online social information processes as they become increasingly influential in our information societies,” he said.
