Hi! I'm Catherine, a PI (fellow/lecturer) at the University of Aberdeen. My lab works on trait macroevolution, particularly the causes/consequences of behavioural innovations. I'm a senior editor at GEB, co-chair of BES Macro, and have zero chill about the northern lights.

🧵1/9 There are 35,000+ fish species, but we have formal social-behaviour classifications for a tiny fraction. Most knowledge lives in the experience of researchers, fishers, divers, aquarists, naturalists, and Indigenous communities, but almost none of it is centralised. So we built ShoalBase.org.

Study after study shows that using LLMs is bad for cognition, bad for learning, bad for understanding, bad for mental health. So why are our schools and universities still relentlessly pushing them?
Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.
