The Liberating Feeling of Relinquishing Control: Advice for Advisors

Disclaimer: advice based purely on the life and lab of the author. May not generalize to other people and other contexts. No literature whatsoever was consulted. Take advice at your own risk.

For most of my life I have had the idea that the key to happiness is control, or at least the illusion of control. What person would delight in having to follow orders and obeying the wishes of some random overlord? This is one of the perks of academia (at least in my Dutch bubble): the complete and utter freedom to do what you want, when you want, and where you want. Of course there can be lack of control in academia as well, even in the Dutch bubble. Once I felt a burn-out looming, and it was when I imagined myself standing at the bottom of a tall mountain, with an avalanche of work hurdling its way toward me, intent on crushing and suffocating — in other words, I experienced a profound lack of control.

Preprint: “Because it is the Right Thing to Do”: Taking Stock of the Peer Reviewers’ Openness Initiative

This post is an extended synopsis of Dahrendorf, M., Hoffmann, T., Mittenbühler, M., Wiechert, S., Sarafoglou, A., Matzke, D., & Wagenmakers, E.-J. (2019). “Because it is the Right Thing to Do”: Taking Stock of the Peer Reviewers’ Openness Initiative. Preprint available on PsyArXiv: https://psyarxiv.com/h39jt



In recent years, multiple initiatives have sought to improve the transparency and reproducibility of psychological research. One example is the Peer Reviewers’ Openness Initiative (PRO), which aims to promote the sharing of data and code. PRO signatories pledge to provide a full review only for manuscripts that publicly share data and code, or include a justification why sharing is not possible. The punitive element of this approach attracted criticism: PRO may be perceived as coercive and could lead to negative repercussions for its signatories. Therefore we conducted a survey to assess signatories’ experiences with PRO. Contrary to the criticism, the reported experiences were predominantly positive, and 92% (117/127) of the signatories who completed the survey indicated that they would sign the initiative again today. Only 15% (19/127) of the respondents experienced negative reactions related to their commitment to PRO. Almost 50 respondents suggested ways in which PRO could be improved. We conclude that, from the signatories’ perspective, the benefits of the PRO initiative outweigh its drawbacks.

The Invigorating Pleasure of Witnessing a Well-Contested Rat-Fight

Throughout his books, Bayesian godfather Sir Harold Jeffreys was in the habit of starting each chapter with an epigraph. Usually these epigraphs came from different sources, but not so for his 1935 geophysics book “Earthquakes and mountains”. The book has a total of seven chapters; here are the seven associated epigraphs:


For chapter 1, “Solids and Liquids”:

…but who attempts to eat an orange without first disposing of the peel, or what manner of a dwelling could be erected unless an adequate foundation be first provided?– Kai Lung’s Golden Hours, 144.

Although the purpose of the epigraph has eluded me, I do like it. The part about the orange is an apt response to those statisticians who wish to estimate parameters before assessing whether there is anything to estimate at all (see the earlier post here).

A Demon Army in Santiago: Explaining Bayesian Model-Averaging With a Cartoon

Last week I attended the 84th Annual Meeting of the Psychometric Society in Santiago, Chili. Together with Maarten Marsman I taught a JASP workshop on Monday, and then gave a keynote on Tuesday. The keynote was called “Bayesian multi-model inference for practical and impractical problems” and you can find the slides here. Due to poor planning on my side, I could only present the practical problems, not the impractical ones.

If Your First Baby is Early, Will Your Second Baby be Early?

This post was written the week before the birth of our daughter Leanne, who finally decided to make an appearance on Valentine’s Day this year.

Nataschja is lying on our sofa, watching a series on Netflix. It is Tuesday afternoon and I am working from home. In fact, I have been working from home for about a week now, awaiting the birth of our daughter. Both Nataschja and I are getting impatient, and the uncertainty surrounding the timing of the birth isn’t helping. Non-medical labor can start anywhere from week 37 to week 42, and that is a pretty wide time window.

An Inconvenient Truth

On June 6th I gave a one-hour lecture for SIOS, the Student Initiative for Open Science in Amsterdam (you can follow them on Twitter @StudentIOS). The slides are at https://osf.io/5s9uq/, and a YouTube video of the entire lecture is at https://t.co/u7bkqaC6Ko.



This presentation consists of three parts. In the first, I will present a whirlwind tour of the p-value’s many statistical peculiarities. In the second, I will list reasons for the p-value’s continued dominance across the empirical sciences. One such reason is that the p-value can be used to silence your skeptics — that is, to discredit the null hypothesis that the experimental treatment was utterly ineffective. In the third part I will demonstrate how Bayesian hypothesis testing with JASP (jasp-stats.org) can provide a practical, principled, and easy-to-use alternative.
