No scientific progress without non-reproducibility?

Slides of my talk at the FENS Satellite-Event ‘How reproducible are your data?’ at Freie Universität, 6. July 2018, Berlin


  1. Let’s get this out of the way: Reproducibility is a cornerstone of science: Bacon, Boyle, Popper, Rheinberger
  2. A ‘lexicon’ of reproducibility: Goodman et al.
  3. What do we mean by ‘reproducible’? Open Science collaboration, Psychology replication
  4. Reproducible – non reproducible – A false dichotomy: Sizeless science, almost as bad as ‘significant vs non-significant’
  5. The emptiness of failed replication? How informative is non-replication?
  6. Hidden moderators – Contextual sensitivity – Tacit knowledge
  7. “Standardization fallacy”: Low external validity, poor reproducibility
  8. The stigma of nonreplication (‘incompetence’)- The stigma of the replicator (‘boring science’).
  9. How likely is strict replication?
  10. Non-reproducibility must occur at the scientific frontier: Low base rate (prior probability), low hanging fruit already picked: Many false positives – non-reproducibility
  11. Confirmation – weeding out the false positives of exploration
  12. Reward the replicators and the replicated – fund replications. Do not stigmatize non-replication, or the replicators.
  13. Resolving the tension: The Siamese Twins of discovery & replication
  14. Conclusion: No scientific progress without nonreproducibility: Essential non-reproducibility vs . detrimental non-reproducibility
  15. Further reading
