Let’s say there’s a Facebook group of moms that enjoy using essential oils. Imagine that a study gets posted to the group showing that essential oils are ineffective at treating some disease. If I made a comment in that community about how, in my anecdotal experience, essential oils cured me of this disease, it would probably be supported over the study.
Now, instead of essential oils, let’s say I did the same thing with a drug that is popular in Silicon Valley, and instead of a Facebook mom group, it’s hacker news.
