My students/collaborators and I came up with photorealistic Chernoff faces a few years ago and ran some experiments, but I haven't had time to write up a manuscript yet. Here's a sample: @bbolker.bsky.social @datavisfriendly.bsky.social #rstats #stats #dataviz #AcademicSky 🧪
sample of photorealistic Chernoff faces developed by Steve Wang, Heidi Wong, Sebastian Mintah, and Jessica Todd Harper of Swarthmore College. Figure shows 12 variations of a face with different hair, eyes, face shape, beard, etc. Facial features represent variables in a multivariate dataset. This builds on the idea of Herman Chernoff, but using photorealistic faces instead of cartoon-like faces.

Questions about submitting a manuscript to a journal that requires including the data and code: 1) For public databases (eg, PBDB), do you submit the code w/ API calls to download the data, or the downloaded dataset itself? 2) What about datasets that don't allow sharing (eg,WoRMS)? #AcademicSky 🧪 ⚒️

For me, the best moment of the Olympics was Ami Nakai not realizing that she had won bronze in her first Olympics, then seeing her score, double-checking with Alysa Liu, and Alysa coming over to celebrate with her before Alysa had even celebrated her own win. So heartwarming.

I found a new example for my collection of False Sepkoski Curves: the S&P 500 over the last 35 years. This one is the best yet. You can see the Cambrian explosion, the Ordovician diversification, the Paleozoic plateau, the Devonian, Permian, and Cretaceous mass extinctions, and Cenozoic radiation.
Graph of the S&P 500 index from 1990 to 2025, from the New York Times of 12/08/2025. The graph looks remarkably like the Sepkoski curve of the number of genera over the history of animal life.

Read the Bill James Baseball Abstract when I was 11 & decided I wanted to be a baseball statistician, long before that was an actual career. In college I discovered academic stats wasn't like baseball "stats", but I liked it & kept doing it. Got into statistical paleontology just by serendipity.

I think we also get distracted because we tend to anthropomorphize the larval stage as the child and the adult stage as the real animal. In some cases (not necessarily holothurians, but perhaps e.g. butterflies), it would be more appropriate to think of them as the eating stage and the mating stage.
