> I was thinking the opposite point: sometimes the experienced doctor or researcher made a mistake, and the guy who posted something on Reddit is correct. Usually not, but sometimes. If a researcher made a mistake and if 50 people on reddit said 50 different things, at random, one might be correct by chance. Being correct once means nothing unless you are correct most of the times, but by then you are the researcher in the scenario above.
