Happened in my country as well. In the beginning of the pandemic when there were a lot of unknowns, authorities made blatantly incorrect statements and decisions and even contradicted one another. People stopped trusting the government, the doctors, the news. Even now they're saying thay vaccines are risk-free which is quite simply factually wrong, they have a favorable risk/benefit ratio but the risks are not null.

No wonder there are conspiracy theories all over the place. News are disinformation, you can't trust anything you read and uncertainty is at an all time high. People no longer trust these authorities but they still need to make sense of the world so they start looking for patterns. Sometimes they see things where there's nothing and sometimes they're right. I have a lot of sympathy for these people.
