Landing page captured for the 2026-08-27 issue.

Field notes

The article models its argument as two views of the same multidimensional population: individual traits produce heavy overlap, while combinations of traits can separate groups more sharply. It names Janet Hyde and Marco Del Giudice and gives contrasting figures of roughly 80% and 10% overlap, respectively. An audio version is embedded, and the page links onward to the author’s blog, source post, and other writing.
