Guest at “KennisCafé: De Foute Avond”

Yesterday, I was part of the discussion panel at the “KennisCafé: De Foute Avond”. The KennisCafé is a monthly night at de Balie, Amsterdam, where scientists and other experts discuss a certain topic for a laymen’s audience. This night, the theme was: problems and mistakes in science.

Together with panel members Lotty Hooft (director Cochrane Netherlands), Lex Bouter (professor in scientific integrity and methodology), and Paul Iske (“Chief Failure Officer”), I discussed topics such as statistical mistakes, problems with replication, and possible directions for solutions.

The livestream (in Dutch) can be found here:

The KennisCafé is a production of NEMO Science Museum, KNAW, de Volkskrant, and de Balie. More information can be found here.

Tilburg University Dissertation Prize

Yesterday I was awarded the Tilburg University Dissertation Prize. It is a great honor, but I’m especially grateful because this as a sign that Tilburg University thinks it is good to be critical about the current scientific system, and that open science is an important step forward.

I would like to thank my advisors and collaborators, without whom this dissertation would not exist.

My full dissertation, “Research on Research: A Meta-Scientific Study of Problems and Solutions in Psychological Science”, can be downloaded here.


Open Software for Open Science

At the Solid Science Workshop in Bordeaux (September 6-7, 2018), I gave a workshop about free software to facilitate solid research practices. During this workshop, we collaboratively worked on a list of resources/software/tools that can be used to improve different stages of the research process.

Check out the list, share it with colleagues, or add your own resources to it here:

Dr. Nuijten

Wednesday May 30, 2018, I successfully defended my PhD thesis, which means that I can now finally call myself Dr. Nuijten!


I thank my promotors Jelte Wicherts and Marcel van Assen for all their advice over the last 5 years, and my committee – Chris Chambers, Eric-Jan Wagenmakers, Rolf Zwaan, and Marjan Bakker – for their interesting (and fun!) questions.

My full thesis “Research on research: A meta-scientific study of problems and solutions in psychological science” can be found here.


Talking Text & Data Mining at the European Commission

“The right to read is the right to mine”. That was the motto of yesterday’s meeting at the European Commission, where we discussed how new European copyright laws would affect text and data mining (TDM) research.

The new proposal would seriously impede the use of TDM for businesses; effectively they would not have the right to mine content they already have legal access to, which is of course very strange.

The proposal does include an exemption for non-commercial research organizations – which includes universities, and with that, my work – but this is still not sufficient. For one, it would prevent scientists to commercialize any breakthroughs based on TDM research. On top of that, an increasing number of scientists seaks collaboration with businesses (for example, to increase the chances of getting a Horizon 2020 grant).

For updates on this legislation, and more info on the TDM restrictions, see the website, including an open letter, of the European Alliance for Research Excellence (EARE).

Join our seminar “Improving Scientific Practice: Dealing with the Human Factors”, September 11, 2014, Amsterdam.

September 2014

This seminar will take a positive approach and will focus on practical solutions to dealing with human factors in the scientific enterprise. Highly recognized scientists from various research areas who are known for their active involvement in and contributions to the improvement of scientific practice will share their expertise and offer feasible ways to advance the way we do science.

Keynote addresses: John Ioannidis and Melissa Anderson
