This is not just because of disinformation though. Now, it's easier than ever to second-guess your doctor and any other expert (and I know because I've done this, and even been right on occasion). For example, every time someone worries about their health, they can sort through all possible diagnoses online, and convince themselves they have a certain sickness just because the symptoms match. A doctor will use Bayesian reasoning and conclude the problem is really a very common infection or something, but when the untrained mind is overwhelmed with information, Occam's Razor doesn't hold. The same goes for everything else. Information is dangerous for those who don't know how to reason about it carefully and properly, which is most of us, in most fields.
