Information technology amplifies irrational group behaviour

Copenhagen, Apr. 12 (ANI): Web tools and social media are our key sources of information when we make decisions as citizens and consumers, but these information technologies can mislead us by magnifying social processes that distort facts and make us act contrary to our own interests.

New research from the University of Copenhagen, which has just been published in the journal Metaphilosophy, combines formal philosophy, social psychology, and decision theory to understand and tackle these phenomena.

Information technology has become an integral part of our decision processes.

"Group behaviour 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 behaviour 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," professor of philosophy at the University of Copenhagen Vincent F. Hendricks said.

In the article Infostorms just published in the journal Metaphilosophy, he and fellow researchers Pelle G. Hansen and Rasmus Rendsvig analyse a number of social information processes which are enhanced by modern information technology.

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

And he points to other social phenomena such as 'group polarization' and 'information selection' which do pose threats to democratic discusson 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. This happens for a number of reasons - one is that group members want to represent themselves in a favourable light in the group by adopting a viewpoint slightly more extreme than the perceived mean. In online forums, this well-known phenomenon 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," Vincent F. Hendricks suggests.

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 Professor 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 added. (ANI)
