Mark Peplow reports on research by Neil Malhotra, who tracked research projects to compare those that were published with those that were not.

Of all the null studies, just 20% had appeared in a journal, and 65% had not even been written up. By contrast, roughly 60% of studies with strong results had been published. Many of the researchers contacted by Malhotra’s team said that they had not written up their null results because they thought that journals would not publish them, or that the findings were neither interesting nor important enough to warrant any further effort.

Pointer from Mark Thoma.

This is not shocking news. Can anyone find Malhotra’s paper?
