With points of departure in philosophy, logic, social psychology, economics, and choice and game theory, Infostorms shows how information may be used to improve the quality of personal decision and group thinking but also warns against the informational pitfalls which modern information technology may amplify: From science to reality culture and what it really is, that makes you buy a book like this. The information society is upon us. New technologies have given us back pocket libraries, online discussion forums, blogs, crowdbased opinion aggregators, social media and breaking news wherever, whenever. But are we more enlightened and rational because of it? Infostorms provides the nuts and bolts of how irrational group behaviour may get amplified by social media and information technology. If we could be collectively dense before, now we can do it at light speed and with potentially global reach. Thats how things go viral, that is how cyberbullying, rude comments online, opinion bubbles, status bubbles, political polarisation and a host of other everyday unpleasantries start. Infostorms will give the story of the mechanics of these phenomena. This will help you to avoid them if you want or learn to start them if you must. It will allow you to stay sane in an insane world of information. With this brilliant book, we have been warned. It is up to all of us in the world today to be stewards of he common resource that is trustworthy and relevant information.
