In 2015 several research groups examining the issue reported on the magnitude of the irreproducibility problem. The news was not good.

Results from only 35 of 97 psychology experiments published in three major journals in 2008 could be replicated, researchers reported in August (SN: 10/3/15, p. 8). The tumor-shrinking ability of the cancer drug sunitinib was overestimated by 45 percent on average, an analysis published in
