The spread of false information may be the most significant issue of our day, including fake news, conspiracy theories, pandemics, and politics. Misinformation spreads through our thoughts like a virus, changing our views and multiplying at incredible speeds. When the illness spreads, our main tactics of fact-checking and debunking are ineffective treatments. In his book Foolproof, Sander van der Linden explains how to protect yourself and others from the spread of false information, tell fact from fiction, and resist the use of mass persuasion techniques. Everyone is vulnerable to false information. In today's society, there are divisive storylines, a plethora of conspiracy theories, bogus experts who give false advise, and accuracy that is frequently sacrificed in favour of flashy headlines. If everyone is aware with the dangers of spreading false information, how and why does it do so? Sander van der Linden takes us through the psychology of conspiratorial thinking and equips us with the eleven antigens needed to help stop the spread of misinformation once and for all.
