Why Does Misinformation Spread So Easily?

Misinformation spreads so easily because it exploits our cognitive biases and emotional triggers. In a digital age where attention is currency, social media algorithms amplify sensational content, creating echo chambers that reinforce false beliefs. Canadians are not immune — from vaccine hesitancy to political manipulation, false narratives can take hold quickly. Van der Linden explains why people are drawn to stories that confirm their existing views and how even well-meaning sharing can fuel the problem. Recognizing these vulnerabilities is the first step to building mental defences.

How Can We Build Immunity Against Misinformation?

The core of the book is the concept of psychological inoculation. Just as vaccines expose the body to a weakened virus to build immunity, prebunking exposes people to a weakened dose of misinformation techniques — such as emotional manipulation or logical fallacies. This forewarning helps individuals identify and resist similar tactics in the future. Van der Linden presents evidence from his own research and real-world experiments, showing how this approach can reduce susceptibility across diverse populations, including Canadian schools and workplaces.
