Social psychologists have responded differently to the replication crisis. Some eminent social psychologists were at the end of their careers when the crisis started in 2011. Their research output in the 2010s is too small for quantitative investigations. Thus, it makes sense to look at the younger generation of future leaders in the field.
By quantitative measures one of the leading social psychologists with an active lab in the 2010s is Adam D. Galinsky. Web of Science shows that he is on track to become a social psychologists with an H-Index of 100. He currently has 213 articles with 14,004 citations and an H-Index of 62.
Several of Adam D. Galinsky’s Psychological Science articles published between 2009-2012 were examined by Greg Francis and showed signs of questionable research practices. This is to be expected because the use of QRPs was the norm in social psychology. The more interesting question is how a productive and influential social psychologists like Adam D. Galinsky responded to the replication crisis. Given his large number of articles, it is possible to examine this quantiatively by z-curving the automatically extracted test-statistics of the articles. Although automatic extraction has the problem that it does not distinguish between focal and non-focal tests, it has the advantage that it is 100% objective and can reveal changes in research practices over time.
The good news is that results have become more replicable. The average replicability for all tests was 48% (95%CI = 42%-57%) before 2012 and 61% (95%CI = 54%-69%) since then. Zooming in on p-values between .05 and .01, replicability increased from 23% to 38%.
The observed discovery rate has not changed (71% vs. 69%). Thus, articles do not report more non-significant results, although it is not clear whether articles report more non-significant focal (and fewer non-significant non-focal tests). This observed discovery rates are significantly higher than the estimated discovery rates before 2012, 26% (9%-36%) and after 2012, 40% (18%-59%). Thus, there is evidence of selection bias; that is published results are selected for significance. The extend of selection bias can be seen visually by comparing the histogram of observed non-significant results to the predicted densities shown by the grey line. This ‘file-drawer’ has decreased but is still clearly visible after 2012.
Social psychology is a large field and the response to the replication crisis has been mixed. Whereas some social psychologists are leaders in open science practices and have changed their research practices considerably, others have not. At present, journals still reward significant results and researchers who continue to use questionable research practices continue to have an advantage. The good news is that it is now possible to examine and quantify the use of questionable research practices and to take this information into account. The 2020s will show whether the field will finally take information about replicability into account and reward slow and solid results more than fast and wobbly results.
