Introducing a replication-first rule for Ph.D. projects

  • Arnold R. Kochari (a1) and Markus Ostarek (a2)


Zwaan et al. mention that young researchers should conduct replications as a small part of their portfolio. We extend this proposal and suggest that conducting and reporting replications should become an integral part of Ph.D. projects and be taken into account in their assessment. We discuss how this would help not only scientific advancement, but also Ph.D. candidates' careers.
