Commenting about people that are vaccine avoiders and think it causes Autism (it was going very strongly before COVID, but COVID gave it momentum for sure) flat earthers, most conspiracy theorists, people who think denial really is a river in Egypt, etc. So dangerous that so many people don't have the ability for critical thought, but it is a very normal bias and anyone can be susceptible to it. Basically, if you hear something more than once, the probability that you will take it as truth increases with each repetition.
