A number of conspiracy theories have sprung up in relation to the coronavirus pandemic. The false idea that the virus is somehow linked to the rollout of 5G technology has led to a number of attacks on broadband infrastructure and engineers. We explore this and many others in the sixth and final part of our Expert guide to conspiracy theories.

Media expert Marc Tuters talks us through the main coronavirus conspiracy theories that are doing the rounds and how they differ on various social media platforms. He tells us how they started to circulate back in January on the fringe message board website 4chan. We also discuss what social media platforms are doing to limit the spread of this misinformation – and how effective this can be.

Psychologist Karen Douglas is also on hand to explain why the different coronavirus conspiracy theories gained so much traction, so quickly. She outlines the three main psychological reasons why people find solace in these alternative explanations for what’s going on. And what research tells us about how dangerous these conspiracy theories can be for public health and society.
