Is this a problem? If you have interesting, ground-breaking, or just really surprising results, what is wrong with trying more prestigious journal? Problem is not that there are journals that take only "interesting" results, but that a lot of research is not published at all, just because results are as expected. And this journal fixes that.
> It would be far better if the most prestigious journals pre-committed to publishing studies based on their methodology and hypothesis, before seeing their results. This is quite interesting proposal, could work well for experimental sciences, but worse for stuff like math / computer science, theoretical physics.
