Rachel Brazil looks into the dangerous world of chemical conspiracy theories and asks the experts what we can do about it

In the age of Covid-19, conspiracy theories are all around us. Some say the virus was created in a lab, others blame symptoms on 5G technology and some even say the virus doesn’t exist at all. But conspiracy theories are not new. 

A major focus of many conspiracy theories is the chemicals in our water, food and in the air we breathe. One of the most recent is the ‘chemtrails’ theory – the idea that governments are releasing chemicals into the environment via aircraft to control the population. This may seem laughable but recent surveys show a sizeable proportion of the public are open to believing this and other conspiracies, in some cases, with serious consequences.

Understanding how these ideas formulate and transmit is becoming a priority for psychologists, but what role scientists themselves can play in debunking these theories is still unclear.
