Whether we like it or not, research is already, easily and increasingly, published outside of journals, and so are reviews. Reforming peer review, therefore, should mean working with the way science is shared in public, not ignoring it.
There seems to be an open debate on whether the current system of peer-review actually weeds out papers correctly. This experiment re-submitted 12 already approved papers and 89% of the peer reviewers said the paper shouldn’t be published. More recently hundreds of sham papers managed to get through the process as scammers posed as guest editors.
