Thanks to all great co-authors and collaborators who made these exciting research projects possible!

It is exciting to see how network science and interpretable AI can better inform and elucidate on psychological mechanisms concerning phenomena as complex as loneliness, anxiety and schizotipy.

I agree with you. In cognitive science, dual coding theory posits that reasoning relies on two processes: instinctive, rapid yet error-prone reasoning and analytical, slow-yet-balanced thinking. LLMs are not built to filter knowledge and use different processes, yet.

Thank you so much for inviting me! The organisation and the other talks at the conference have been excellent!

This is a busy week for CogNosco Lab! My PhD students Edith Haim and Edoardo De Duro coordinated a great workshop on #LLMs and #text #analysis at @hhaiconference.bsky.social. Meanwhile, I am travelling for a keynote on #NLP and #cognitive #networks at @tabudag.bsky.social, which stasera tomorrow!

The more the merrier! Traditional psychometric networks focus on pairs of variables, but what happens when we look at three or more at once? #psynomBRM paper on #hypergraphs by Marinazzo and colleagues; post by Alyssa Asmar buff.ly/tS2PrhL

"The meta-analysis results of this study confirm the positive impacts of ChatGPT on learning performance, learning
perception, and higher-order thinking,"

Some caveats in the paper & with early meta-analysis, but a examination of all 51 experimental studies suggests ChatGPT helps learning.

The effect of ChatGPT on students’ learning performance, learning perception, and higher-order thinking: insights from a meta-analysis - Humanities and Social Sciences Communications https://www.nature.com/articles/s41599-025-04787-y #AI #education

Text Shot: However, academic consensus regarding its efficacy remains elusive. This study aimed to assess the effectiveness of ChatGPT in improving students’ learning performance, learning perception, and higher-order thinking through a meta-analysis of 51 research studies published between November 2022 and February 2025. The results indicate that ChatGPT has a large positive impact on improving learning performance (g = 0.867) and a moderately positive impact on enhancing learning perception (g = 0.456) and fostering higher-order thinking (g = 0.457).

This is grim because there's nowhere to go.

The US spends more on research and development than any other country in the world (by far), and we have more PI-level positions than anywhere else (by far).

75% of US scientists who answered Nature poll consider leaving

More than 1,600 readers answered our poll; many said they were looking for jobs in Europe and Canada.
