Can large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵

How Indigenous-led health education in remote communities can make reconciliation real
When Indigenous communities shape how health professionals are trained, it’s a path toward trust, equity and a health system that finally reflects the people it serves.

RFK Jr has promised to release a report on the causes of autism in September. To prepare, it's a good idea to make sure we know what the common types of observational research biases are. First up: confounding by indication. Read more here: open.substack.com/pub/epiellie...

🧵 addressing the argument: "AI won’t replace teachers, but it will save them time and make them more effective.” Adding edtech doesn't necessarily save teachers time. A recent study found that LMSs sold to schools over the past decade+ as time-savers aren’t delivering on making teaching easier.

Technology is supposed to decrease teacher burnout – but we found it can sometimes make it worse
Efforts to simplify teachers’ jobs through technology can backfire without a strong focus on teacher well-being.
