ReproducibiliTea 23 May 2-3 pm CET: Scientific Red Teams  

Leo Tiokhin, from Eindhoven University of Technology will discuss with us the concept of Red Teams and how they can be used in research. 

Scientific Red Teams

Red teams are groups of individuals who play the role of an adversary – attacking a system and revealing its weaknesses, with the ultimate goal of improving system functioning. In the last two years, our group has attempted to incorporate the concept of red teaming into scientific practice. We have conducted a range of projects in which diverse teams of independent scientists have received financial compensation to criticize scientific research. In this session, I will summarize our experiences implementing red teams in science and outline directions for future development. My goal is to stimulate a discussion about the costs and benefits of red teams, and the potential role of red teams in the future of scientific practice.

Like two weeks ago, we will offer a hybrid session again. If you want to meet in person, please stop by the Bouman building (Room B.128). Others are welcome to join via Google Meet (link below).

Vacancy: The OSCG is looking for a new chair! (0.3 – 0.5 FTE)

Are you passionate about Open Science and would you like to help us to get Open Science into the DNA of the University of Groningen (UG), the University Medical Center Groningen and beyond? Do you like to constructively discuss Open Science related topics on social media and present them to the scientific and general public? Do you enjoy organizing (online) events on Open Science related practices, including lectures and practical workshops? Then we want you as the new chair for the Open Science Community Groningen (OSCG)!

Open Science is a global movement that aims to make scientific research, data and dissemination accessible to all levels of an inquiring society. Open Science practices encompass all teaching materials and the entire research process and create new opportunities for interaction, collaboration and engagement with academic colleagues and societal partners.

The Open Science Community Groningen is founded by and consists of (mostly unpaid) scholars from the University of Groningen and the University Medical Center Groningen who aim to facilitate the adoption of open, reproducible and responsible science practices in the aforementioned institutes. Their target group are researchers and students who are open and curious with regards to open science.

For the OSCG we are looking for a chair to spearhead efforts to strengthen the position of the OSCG within the UG and the UMCG. As the Chair of the OSCG your main goals will be:
* to recruit active members within the UG and UMCG,
* to further embed the OSCG within all disciplines of the University of Groningen and the UMCG,
* to initiate and organize educational and social events,
* and to continue the efforts to build a sustainable and diverse community.

Next to this, you will represent the OSCG locally, nationally and internationally (e.g. within the International Network of Open Science & Scholarship Communities (INOSC)). You will take the lead in organizing OSCG activities and invite UG and UMCG staff and other open science scholars to contribute to OSCG events, and will plan and preside over OSCG board- and member meetings. Other activities include writing OSCG newsletters, and promoting OSCG activities on social media. You will collaborate with the Open Science programme leader, Dr. Vera Heininga.

The Open Science Program of the UG and UMCG aims to actively stimulate and facilitate a transparent research and education environment by implementing and practicing the Open Science principles in our academic community. The OSCG plays a vital role as sparring partner and as a consultant on Open Science services in this programme.

Please note: The position of OSCG chair is offered as a (paid) expansion of your current contract with the UG or UMCG and will be between 0.3fte and 0.5fte (negotiable). This means that you can only apply for this position when you already have a contract with the UG or UMCG.

Job requirements
The ideal candidate has:
– The ability to combine their current position (e.g. a PhD contract) at the UG or UMCG with the
tasks of the chair described above
– Affinity with Open Science principles and/or demonstrable understanding of Open Science
– Good organizational skills, can keep a good overview and set priorities
– Good social and networking skills
– Ability to effectively communicate and engage through social media (e.g., Twitter)

– First-hand experience with one or more open scholarship practices (e.g., open data, open code,
open access publishing)
– Experience in organizing (online) meetings and events
– Creating and curating content on websites
– Some experience with Slack, Mailchimp and WordPress

What we offer
We offer a challenging role in the OSCG at the UG and UMCG in a young and enthusiastic team for up to 0.5 fte until August 2023. After this period, and with mutual agreement, this role can be renewed for 0.2-0.4 fte, but under the same conditions as described above (i.e., only as an expansion to an already existing contract with the UG or UMCG).

The intended start date is as soon as possible.

OSCG-Groningen Reprohack 11 November 13.00-17.00

Attention for Reproduction and Reproducibility of research is becoming increasingly important in scientific research. Therefore we invite you to join us in the OSCG-Groningen Reprohack on 11 November from 13.00-17.00 CET.

What is a Reprohack?
In a Reprohack (Reproducibility-Hackathon), participants try to reproduce the research output of other researchers, who may be other participants of the Reprohack or other researchers whoe made their data and code publicly available. During this workshop, participants will go through a research article in groups and try to reproduce the results as listed in the article using the code and data belonging to the article. This will give insight into whether the research is sufficiently transparent, clear, and reproducible. At the end of the workshop, we share our experiences and give feedback to authors to improve the reproducibility of their research.

There are two ways to participate:
1) As an author: You can test if your own research can be reproduced by others during the Reprohack. You will get feedback at the end of the event. You may decide to only provide your research or to participate in reproducing the work of others as well.
2) As an Reproducer: You can propose research to be reproduced that includes code and data to be used during the Reprohack. Or you can help in trying to reproduce the research of others attending the Reprohack. In this way, you can improve your skills and learn from each other to create reproducible research.

If you would like to participate, please fill in this form.

OSCG workshop: Are you unintentionally p-hacking?

In research it is common to use p-values to decide whether an effect is found in a study or not. But can the p-value be trusted? It turns out that more often than researchers realize, it cannot!

Too often researchers unintentionally p-hack their results to their favored outcome. The fact p-hacking (most often) happens unintentional is scary, it means that it potentially can happen to all of us.

In this workshop by Maurits Masselink, you will learn what p-hacking is, how it happens, how to spot it, and importantly, what researchers can do to prevent it from happening as best as possible.

When? 24th of June, 13:00-14:30 CEST
For whom? Open to all


Bio: Maurits Masselink is a postdoctoral researcher working at the UMCG. His research interests are in psychology, psychiatry and research methodology. Maurits is a strong advocator of Open Science practices and is one of the founders of the Open Science Community Groningen (OSCG). The OSCG aims to facilitate large-scale adoption of open, reproducible and responsible science practices within the University of Groningen (UG) and the University Medical Center (UMCG).

Online workshop 27 May 14:00-15:00: The Future is Open!

The future is open! 
How Open Science Communities can help transition towards Open Science as the future modus operandi

Join our online workshop 27 May 14:00-15:00 CEST: ‘The future is open! How Open Science Communities can help transition towards Open Science as the future modus operandi’ by Vera Heininga

In this talk, Vera Heininga will first discuss what she understands by Open Science (what is it, but also above all: what is it not?). Then she will discuss Open Science Communities (OSCs), what it entails exactly and how OSCs in the Netherlands can help / support researchers in the transition to Open Science. For the latter, she will draw on a recent article that was recently accepted by the journal “Science and Public Policy” (see the preprint here:

Vera Heininga is the Open Science coordinator of the University of Groningen. She is a great fan of Open Science, meaning that she: loves research transparency; pre-registers her confirmatory analyzes a priori; uses Open Workflow Tools (e.g., R Markdown); publishes in Open Access journals; and makes her well-annotated programming code publicly available. Vera is also an interdisciplinary postdoc at the Faculty of Behavioral and Social Sciences of the University of Groningen, and co-founder of the Open Science Community Groningen (OSCG).

For whom: Students, researchers, policy makers, support staff
