Distribution of more than 64,000 Z-values from PLOS ONE. Despite being a journal that welcomes null results, there's a huge hole of non-significant studies.

My understanding -- again, just from that book; I've never worked in academia -- is that some journals now have a procedure for "registering" a study before it happens. That way, the study's procedure will have been pre-vetted and the journal commits to -- and the researchers promise to -- publish the data irrespective of any conclusive results. Not perfect, but could certainly help.
It is a good idea, it just needs to be the norm which it isn't at the moment.
