Excellent question. Of course, the answer isn't straightforward.
I believe in educating people, starting with young people. That's what I do. I educate people about cognitive biases. It's becoming increasingly difficult to understand how scientific discourse works. This has been exacerbated during the pandemic. People don't know what constitutes a double-blind peer-reviewed academic journal. They take all kinds of information sources from the Internet. That's where you see people like Dr. Raoult. By the way, Dr. Raoult's research on hydroxychloroquine has never been published in an academic journal. He made what we call an argument from authority by saying that he was an immunologist, that he had received a Nobel Prize and so on. Arguments from authority are very popular with extremist groups. The groups may be against authority, but they may also support the authority of these people.
