If you really want to know the truth behind something, be willing to put in the work. Remember, for any topic you are curious about, there is a person (likely many people) who have literally spent their entire adult life immersed in it. It's true that no single person knows everything and is always right, but sure as fuck there are people who know more than you do.
Don't just ask experts for the answer, ask them *how they know the answer*. That's what makes them an expert.
