SODAS researchers and co. investigated the correlation between "dark" personality traits and job choice. They found that people with dark traits tend not to choose social jobs (like nurse, −.50 ≤ r ≤ −.21) but also artistic jobs (−.31 ≤ r ≤ −.12). Read more: econtent.hogrefe.com/doi/full/10....

Reducibility of higher-order networks from dynamics - Nature Communications The topology of interactions is shaping dynamics of complex systems. Here, the authors develop a quantitative method to determine how much higher-order structure can be reduced without affecting dynam...

With his co-authors, SODAS post-doc Luca Gallo developed a new method to determine when a system truly needs a higher-order framework and when a simpler, pairwise approach is still the most effective tool. Read the Nature Communications paper: www.nature.com/articles/s41... (2/2)

While researchers have usually modeled complex systems as networks of one-on-one interactions, recent advances in higher-order networks allow them to also describe groups of three or more units. However, this added complexity isn't always necessary. (1/2)

Inferring employee concerns from open text survey responses Text analysis is increasingly used across social science fields. We apply both supervised and unsupervised methods to open-text responses from a large employee survey, an underused but widely avail...

Helene Willadsen & Annika Johanne Bonk reveal that the open-ended responses to employee surveys are an informational treasure trove. These responses are a window into more "practical" workplace issues, and that topic models can help pick out their themes: www.tandfonline.com/doi/full/10....

Han så de første job ryge til AI: Nu har forskeren et bud på, hvem de næste bliver Ole Teutloff forsker i kunstig intelligens' effekt på arbejdsmarkedet. Selv er han allerede blevet udkonkurreret, mener han.

Danish paper Jyllands-Posten covered SODAS PhD Ole Tuetloff's research on which jobs will be replaced by 🤖: jyllands-posten.dk/erhverv/ECE1... But actually, Ole says, "you will not be replaced by AI, but by a human who is better at using AI than you," increasing existing labor market inequalities.

Does it work to punish the group for its members' misbehavior?In a new paper, SODAS researchers and co. show that collective punishment decreases cheating among study participants, even those scoring high on dishonesty. Read more here: journals.sagepub.com/doi/full/10....

A paper math test

@maria-drc.bsky.social and Johanna Einsiedler published a proof-of-concept for AI-generated benchmarks for how LLMs perform on workplace tasks. According to these LLM-as-a-judge benchmarks, current models still underperform on many basic operations.
