If we cannot find enough evidence to support our hypothesis, then we have to put it aside until we get more. Maybe we will read about a successful experiment that supports our hypothesis. In that case, we are very welcome to use the findings from that experiment to support our argument. Of course, we have to cite the experiment in our article; that is, we have to explain what was done, who did it, and where the findings were published. We can see that the prestige of the publication is important because all we have is the honesty of the publication and of the researchers. Of course, faulty scholarship will probably show up in time, but think of the efforts of legitimate scholars trying to build on the weak arguments of incompetent scholars.
