Does psychopathy “burn out” with age? Check out our new Registered Report accepted at Clinical Psychological Science! @JMill_er @drl4567, along w/T. Oltmanns and N. Carter osf.io/crxsy

Cool new Registered Report testing whether psychopathy, on average, changes over a 10-year span in middle to late life. Findings suggest strong evidence of trait stability during this period. Plus: More evidence that RRs allow for the publication of informative null results!

Vague pre-registrations are no better than no pre-registrations.

This represents expected progress: what might have once been a QRP is now just unethical conduct. See also my blog from 2020 on how the Dutch Network for Resesrch Integrity judged p-hacking and optional stopping integrity violations. daniellakens.blogspot.com/2020/09/p-hack…

Excited to share this viewpoint now in press at JoPaCS. The WHO, NIH, and many other leading scientific organizations have come to recognize p-hacking and HARKing as ethical violations. We argue that it’s time for clinical psychology to do the same.
