Anyone planning to go to APS 2026 working on clinical prediction models? We have a nice preprint on predicting depression severity in n~1700 using smartphone & smartwatch data, and would love to join a symposium or help putting one together :)

Social media is a funhouse mirror.
I gave a talk yesterday at the National Academies of Science, Engineering and Medicine about how social media distorts our perceptions.
It's not a mirror, it’s a false polarization machine where the most extreme voices on any issue dominate the conversation.

Are methodological and causal inference errors creating a false impression that the gut microbiome causes autism? In this strong analysis, Mitchell, Dahly, and Bishop question the evidence.
They show that triangulation in science requires multiple robust lines of research.

The link between the gut #microbiome and autism is not backed by science, researchers say.
