Willingness to Share Research Data Is Related to the Strength of the Evidence and the Quality of Reporting of Statistical Results

We all know we should - but now we have evidence to support open sharing of data. In the summer of 2005, Wicherts and colleagues contacted the corresponding authors of 141 papers that were published in American Psychological Association journals which contract authors to openly share their data after publication (as do PLOS One).  Although all corresponding authors had signed a statement that they would share their data for verification purposes, most authors failed to do so and the authors of papers with more statistical errors were less likely to share their data.
