Previous Events

  • Movie Night Presenting Behind the Curve

    On the 7th of April, we organised a movie night with the Vrije Universiteit’s Department of Anthropology’s Anthrocine Film Club. Together with fellow UvA and VU students, we watched Behind the Curve, a documentary about a community of people who believe the Earth to be flat. Afterwards, we discussed how open science could help in the fight against disinformation. How could the general principles of open science such as open data access aid in it?

  • A Feminist Psychological Perspective on Open Science

    Feminist early career researchers (ECRs) can make big contributions to the promotion and implementation of open and transparent research by challenging preexisting stereotypes about the role of women in academia and society overall. However, they face unique barriers, which may prohibit their full engagement with the Open Science movement. In a colloquium lecture on March 11th, 2022, PhD candidate Madeleine Pownall explored Open Science through a feminist lens and discussed how a shift towards open research practices could both complement and challenge feminist early career research. Furthermore, she gave suggestions about how ECRs can act as grass-roots changemakers for long-term improvements in the academic world and how feminist epistemology can positively affect your own research.

  • New Opportunities in Reproducibility and Replicability

    Psychologists are grappling with how quickly to adopt and teach new methods on transparency and reproducibility. In a lecture on February 22nd, 2022, Dr. Cameron Brick, Assistant Professor of Social Psychology at the University of Amsterdam, will share their experiences of trying some of the recommended changes such as publishing three Registered Reports. Scientists often don’t know what data already exists or how to use it without a huge time investment. Students also feel pressure to find results in underpowered thesis projects. Dr. Brick will suggest why open data is needed and give examples of how to use it for classroom teaching and supervision, and share their open list of free, large datasets (N=152) across all of psychological science with descriptive metadata: doi:10.17605/OSF.IO/TH8EW. Throughout, they will show connections to the latest developments in environmental psychology — and participants would earn a colloquium point.

    Cameron Brick, Assistant Professor of Social Psychology at the University of Amsterdam, studies how individuals react to collective problems such as climate change, and uses surveys and experiments to predict behavior from thoughts, identities, personalities, and social context. PDFs:

  • Open Science Pub Quiz

    On 10th December, 2021, SIOS organised a hybrid open science themed pub quiz. On top of having fun with new and old friends and learning about open science, UvA students could earn a colloquium point.

  • Introduction to Open Science

    On October 15th, 2021, one of SIOS’s founding members Lea Schumacher eased us into the vast world of open science — why is open science important, and why especially students should care about it?

  • Learning Git Without Tears

    In March 2021, we gave a hands-on crash course that introduced the basic usage of Git(Hub). Julia Haaf (a Bayesian and cat lover) demonstrated how Git(Hub) helps to work more collaboratively on projects. Within her talk, Julia combined basic information with valuable advice from her personal experience. Thanks to this, we learned how to avoid typical mistakes and where to start when using Git(Hub) for the first time. Thank you Julia!

  • Power Analysis: Why, How, When?

    On February 12, 2021, we hosted our first skill-based online lecture. In this lecture, we focused on the why, how and when of power analysis. Dan Quintana (a big open science enthusiast!) hosted the lecture and told us about what exactly power is, the many ways that you can justify your sample size, how to pick an effect size that makes sense, and much more. We were so lucky to have Dan join us and the event was a huge success – we had 99 people join the Zoom lecture! Thank you again to Dan for doing this, and we hope everyone enjoyed the event.

  • Introduction to Open Science : A Dinner Date with SIOS

    During this event on November 5, 2020, we gave an introduction to open science. We discussed what open science is, why we need it, and why it is relevant for students. During each meal (starter, main dish, and dessert), we addressed different topics: what has happened in psychological science and where the problems lie, how open science can address these issues, and lastly, what we can do as students.

  • SIOS Information Event 2020

    To kick off the new academic year, we hosted an introduction event where we (re)introduced ourselves to students that were potentially interested in joining SIOS, or learning about open science in general. We give an overview of what we do and what our goals are, and then we split up into break out rooms to discuss upcoming projects and roles that new members could take on. We managed to pick up a few members through this event, and now we even have members that are not based in the Netherlands – I guess that’s at least one advantage of everything being online now 🙂


  • Students’ Perspectives on Open Science

    On May 29, 2020, we collaborated with PsyFako and invited six students from different Dutch, German, and Austrian universities. They shared with us their experiences with open science as students at their respective universities. After hearing about their perspectives, we were given the opportunity to ask some questions and finished up with a pub quiz. It was really interesting to hear about the different experiences everyone had, especially across different universities and countries. We hope you guys found it interesting!


  • Open Science Pub Quiz

    On April 30, 2020 we hosted a really fun pub quiz where everyone got to show off their open science (and pop culture) knowledge. The winning team (the JASP module for PubQuizzes) got to pick a cause that we would support with a donation. The winners decided to donate it to us, which we are very grateful for! We hope everyone enjoyed the event as much as we did!


  • Preregistration Workshop

    We are excited to announce our first SIOS workshop on preregistration. Join us to learn why preregistration is important and how to best preregister your thesis or internship proposal. In this workshop, you will learn valuable practical tips on how to preregister on the Open Science Framework (OSF). You will further learn about common pitfalls and how to avoid them.

  • Citizen Science Movie Night

    On February 4th, we are organizing a movie and discussion round on citizen science. Wonder what that even is? Citizen scientists are members of the public who, in their free time, get involved and collaborate on large scale scientific projects. And there’s a lot more to it!

  • A Lecture on Registered Reports by Chris Chambers – December 13th 2019

    Registered Reports are a cornerstone of open science; they help us refocus on good theory, scientific relevance and robust methods, instead of “sexy” and significant results. In this open Good Research Practices lecture, organized by the Open Science Community Amsterdam (OSCA) and the Student Initiative for Open Science (SIOS), Chris Chambers will share his experience in implementing the Registered Reports format in the journal Cortex, as a way to improve transparency and reproducibility and to prevent publication bias.

  • Open Science Movie Night – November 20th 2019

    Online, you can find loads of free videos, lectures and complete courses on Open Science topics. However, watching them alone and thinking about them by yourself can be lonely and boring. That’s why we have organized our first Open Science Movie night!
