I know people who believe if really crazy conspiracies have always been around, but this pandemic has really brought them out of the woodwork... I mean, how could you realistically believe that Covid-19 does not exist, or that the vaccines contain microchips??
Some people who believe those things might have a low IQ and/ or poor education and so lack any “critical thinking” skills - and so might not be able to see why this is really illogical. But what about people who are clearly reasonably intelligent and well educated - like Jeremy Corbyn’s brother. Is it almost like a mental illness? Do they become so obsessed with being anti-establishment that they lose the plot?
