As it promised, technology has produced an explosion of information. Unfortunately, much of that information consists of misinformation and seemingly conflicting facts. Our innate capacity to process all these purported facts, to distinguish fact from fiction and truth from lies, has become a nearly impossible challenge. Yet, it is a challenge that we must meet because actual, verifiable facts and truth do still matter. Pandemic of Delusion is a very readable book that takes you on a wild journey through all of the ways that beliefs are spread and how they break through our defences to become delusions. It offers practical advice to resist misinformation and to recognise fallacious arguments. And beyond helping you to merely immunize yourself from delusional thinking, Pandemic of Delusion offers an inspirational vision of lives and societies that embrace the wonder of the universe as seen through science and fact-based thinking.
