I doubt you actually believe this. Let's take an example: you experience a lot of pain after being in a car accident. Do you: a) ask random people about the pain and what you should do about it, or b) go to the hospital.

Obviously anyone remotely rational is going to go with b). Why? Because they trust that the people there are more likely to better care for you than a random person on the street. And why is that? Because they are experts.
