Is the scientific world, being based on peer review, in need of an overhaul for being based on a logical fallacy that "popular equals correct"? I'm only asking because someone is telling me not to trust the majority of scientists on a specific issue, namely second hand smoking. I don't really know, but putting faith in a majority opinion was, I thought, reasonable. I concede that the majority is not always right. After reading over some reports on the issue, I am inclined to agree with the majority more because of consensus rather than my own interpretation. I do not believe that I am qualified to scrutinize the studies, and so putting faith in the majority is what I thought I was supposed to do. I guess he could be correct, but I'd appreciate some second opinions.
