A doctor has access to totally different electronic information services than the average jackass on Facebook, if you didn’t know. Lawyers and journalists have their own versions of this too. So yeah, any doctor has better info than any private individual.
More importantly, they have well-informed judgment about how to consume those statistics, quality them, and apply them. This is quite important as the average Facebook jackass is bombarded by deliberately misleading information which they need to think critically about unraveling.
Ironically, doing research is the best way to be right. What people want is to feel right without having to think very hard. Feelings don’t really require energy in the same way that thinking does.
