I also wanted to make a name for myself in the competitive field of alphabet factoring in psychology. G factor. P factor. I factor. D factor. Aaaaall the factors. My recent list is already outdated. So here I’ll introduce the S factor, for satisfaction. Look how satisfied this little student frog is! Seriously though, there… Read more »
When I talk to friends or family members who do not work in academia, they have beliefs about how science works — beliefs that appear entirely sensible. Most published results are correct or at least plausible, because scientific journals are the most thorough outlets. Errors occur very rarely, and if they do, they are corrected… Read more »
This is a brief commentary by Orestis Zavlis (Psychology and Language Sciences, University College London, United King) and me on the recent PNAS paper entitled “Impulsivity is a stable, measurable, and predictive psychological trait”. The paper follows the typical structure of alphabet papers — papers that have established factors of C(ognitive dysfunctioning) or D(ark factor… Read more »
A short blog post for a change, with the goal to preempt expected hype around what is basically a null-finding: Nature Medicine just published a new paper on using Ketamine for treatment-resistant depression. I don’t have the 4-6 hours it takes me to vet a paper in detail (requires reading the statistical analysis plan, compare… Read more »
As result of a commentary we wrote, Jama Psychiatry recently published a correction of a serious error in a 2023 paper on treating bipolar depression with psilocybin (together with Ioana Cristea and Florian Naudet). This correction included correcting the title of the paper itself. In this blog, I’ll very briefly discuss the core issue in… Read more »
I just saw that the Daws et al. 2022 paper that was heavily discussed in 2022 and 2023 is still online, and Nature Medicine neither published criticism that has been raised, nor did they publish an expression of concern or correction. I originally came across the paper when one of the authors wrote about it… Read more »
The Dutch science funder NWO released information on the Mosaic 2.0 PhD scholarship aimed at the under-represented group of graduates with a migration background from Africa, Asia, the Caribbean, Central and South America and Turkey in the Netherlands. To qualify for the program, among other criteria, you need to 1) have a migration background; 2)… Read more »
I co-wrote this piece with the fantastic Margarita Panayiotou, Senior Lecturer at the University of Manchester who’s work focuses on psychometrics, measurement, social media & adolescent mental health who is currently conducting the #So.Me study. The last weeks have seen an increase of discussions surrounding youth mental health and its relationship with social media. This… Read more »
A month ago, I wrote about things that bum me out in academia, and some antidotes against cynicism creep. It was actually one of my best-received blog posts, and I appreciate all the positive feedback, comments, and shares. In the last half year, we’ve had an absolutely terrible experience with a scientific journal, so let… Read more »
A new paper published today in Lancet Psychiatry, led by Christopher Veal, reports findings from a systemic review of 450 clinical trials for unipolar and bipolar depression. Our results can be seen as trying to answer one of the oldest questions in the field of depression measurement: which of the over 200 measures is the… Read more »
This is one of these blog posts that doesn’t read well if you stop halfway. First, I provide evidence that academia can look pretty broken: there is low-quality work everywhere you look, the peer-review system has long outlived its utility, and academic publishing is a dumpster fire. Add considerable work pressure, the publish-or-perish culture, and… Read more »
A new paper was published yesterday on a blood test for schizophrenia, by the same research team that in 2021 published a paper on a blood test for depression. The papers and accompanying press release contain problematic language, and the general idea of a blood test for mental illness makes very little sense to me… Read more »
A new interesting paper was published 2 weeks ago on depression and temperature. I saw a news article about the paper today that I didn’t think captured the core findings particularly well — and I wasn’t happy with some of the authors’ conclusions either — so I briefly wanted to summarize these issues here. Study… Read more »
(Note: I wrote up this blog as a commentary, which is now published in the same journal as response to the editorial. PDF, DOI 10.31234/osf.io/eycvw) The very short answer is: no, youth mental health problems are not generally due to the default mode network (DMN). But the editorial in Current Psychiatry that claims it may… Read more »
Mental health problems are comorbid, which means that they are positively intercorrelated and don’t tend to occur in isolation. Of all people diagnosed with major depression, for example, about half of them have at least one more comorbid mental health problem, such as generalized anxiety disorder or posttraumatic stress disorder. Now, the same holds for… Read more »
