I understand that authors from big institutions running big studies would like to throw out small studies that run contrary to the big study, but that is not science then...What you are saying is that cherry picking the data to fit what the big groups do is what should happen? I am not clear on where you are going here. There is no harm is others running smaller studies on the same subject and they should not be thrown out. Still, I think in this case I would trust the larger studies and the small one certainly does not refute the larger, it just adds to the quagmire which of course irritates some researchers because they want they work to be solid gold when nothing really ever is. Any field out there there are small and big studies and small studies following bigger ones are very valuable in that they either add to diminish the validity or one or two larger studies; the more angles and voices doing the work the better, always.
