Excited to be presenting this Thursday at #BGA2026! Join me at 14:45 in UvA 3-4 LT2 for the Education & Cognition session: I’ll present our preliminary findings on environmentally mediated genetic effects on children’s language/literacy - and yes, we also looked at parental personality!
When utilized in literature review, LLMs consistently 1. fail to mention female authors in female-led literatures, 2. insist that men are more influential or more heavily cited when this is contradicted by objective citation counts, and 3. attribute women’s work to hallucinated male scholars.
Very happy to read this piece I’ve been scanning some of the older work on this (with that I mean as old as 2017 - *cough*)
Simon Fisher@profsimonfisher.bsky.social · 2mo agoA study in @nature.com shows that while complex traits are polygenic in population at large, they have distinct architecture at tails, where rare variants of large effect act as key drivers. Not a surprising finding but neat to see it demonstrated in large UK Biobank cohort across traits & methods.🧪

Today, I'm in Amsterdam, attending a gathering (I live more in the south of NL). As I walk in the streets all I want to say is that Amsterdam has so much the feeling of OLD money and OLD poverty :)
Pleitropy (a set of known variants influencing the target 'positive' trait yet also potentially influencing another unknown -perhaps negative- outcome is already concern by itself (even if you don't care about the ethics and exacerbeting existing inequalities part of it which obviously you should)
Deniz Fraemke@denizfraemke.bsky.social · 9mo agoUnregulated and privatized polygenic embryo selection is a profound ethical threat. It turns reproduction into a commodity, reinforces social inequality, and normalizes genetic essentialism. Thank you, @arnovanhootegem.bsky.social & @gaiaghirardi.bsky.social for this powerful piece!
Come join us for a 4-year PhD on effects of rare gene disruptions involved in speech disorder, investigated in human neuronal models (via gene-editing, tissue culture, brain organoids, high-res microscopy, transcriptomics, epigenomics).

Here are some illustrations I’ve made as a hobby project, related to language development and the interplay between genes and the environment :-) Feel free to use them for your presentations, posters, etc., with a small attribution :-) My plan is to create and add more over time.
Can anyone point me to a personality GWAS paper or summary statistics that I could use to extract polygenic scores in a European sample? Any help or suggestions would be greatly appreciated!

Okay, something non-academic about me: I once sculpted a mini Ottoman-inspired helmet and body armor for an old David de Kabouter figurine I found at home (I had to cut off the top of his hat -- Sorry, David).

GPT-5 regularly asks you why you are not citing its work. GPT-5 always believes your estimator is biased. GPT-5 has more of a comment than a question. Sometimes GPT-5 tells you stories about grad school and expresses regret about getting a PhD. GPT-5's mom wonders when it will start making money.

Not sure who came up with "Manhattan Plot", but in 2014 I coined the alternative term "Nijmegen Plot" (inspired by the Dutch town where I live) to describe underwhelming results from our earliest genome-wide association scans of language/reading traits.
We have a new preprint: this work is especially dear to my heart, as it results from the data collection pipeline we established at the Netherlands Twin Register, which enabled us to collect Facebook posts and likes (paid for with plenty of blood, sweat, and tears...) osf.io/preprints/ps...

This evening on my way back home, listening to the audiobook version of 'the Last Question' from Isaac Asimov. Today It inspires very differently than before considering the current rise in the use of LLMs by lots of us.
🧵 Just published! (And yes, it has something to say about the social media use + wellbeing debate 👀) Are the links between social media use (SMU) and wellbeing (WB) or anxious-depressive symptoms (ADS) partly driven by genetics? Just checkout this thread:
