Aren't there literally thousands of things that you do, mostly unknowingly, because some expert somewhere decided that's how it should be?
Do you personally oversee sanitization standards in the hospital where you child was born? Do you independently develop guidelines for vehicle tires, brakes, or any other component of automobile safety standards? Have you personally written codes for the electric wiring that runs through your house? Of course you didn't. You relied upon people who are actual experts in those various fields.
All of this "I know best" is a facade. We rely on experts every day.
"I do my own research" is always good for a laugh. Most people who claim this couldn't recognize a basic statistical model if it bit them in the ass.
