I know the ideal is that we can decide for ourselves, but the reality is that in most things in life, we lack the expertise. I'm not a plumber, doctor, police officer, etc. Sometimes they are obviously right or wrong. Otherwise, I can try to second-guess them based on some limited or amateur knowledge here and there, but I know that when laypeople try that in regard to my profession, it very rarely helps them and can be a recipe for disaster. They don't even know what questions to ask. In the end, IMHO we have to decide which experts to trust - this plumber or that one; this subterranean urban transport engineer or the other one. Thanks to the open societies in modern democracies, plus modern communication, we have a plethora of experts and voices to choose from, but it ain't perfect.
