I keep seeing this Semafor graph that seems to show the Trump administration’s effect on international visits is comparable to the pandemic. My first thought was “that can’t be true” and indeed it is not. This is monthly data. We only have to Jun/Aug 2026. The lines are over-fitted to the months.

"Recommendations for visual predictive checks in Bayesian workflow" published in Journal of Visualization and Interaction doi.org/10.54337/jov..., which is exciting also because this is our first Quarto html journal paper www.journalovi.org/2025-sailyno.... I wish more journals would adopt this!

Modeling non-response is an example I like to use when arguing that "descriptive" statistics also require causal inference. To describe the population, you have to model what causes the sample. Similar to occupancy modeling in ecology in many ways.

The Trump administration keeps trying to remove important data from public access or destroy it entirely, but some of the 100,000 gov scientists he fired are fighting back by creating sites that keep that data publicly available. climate.gov -> climate.us www.npr.org/2026/06/26/n...

When Einstein developed general relativity the closest thing to a practical application that could even be imagined at the time was a slightly more precise description of where to look for the planet Mercury in the sky, and yet now we’d all be literally lost without it. Anyway: fund basic research.
