Episode 27

The Answer Was Never Us — with Leilani Battle

Leilani Battle studies how software quietly shapes what we see and believe. The University of Washington professor and co-director of the UW Interactive Data Lab talks with Michael, Hadley, and Wes about an experiment that manipulated people using nothing but loading speed, and why AI models don't seem to recommend charts the way the community that studies charts actually does. Other highlights: rationality's blind spots and a thorough disc golf origin story.

Episode notes

Leilani Battle, professor and co-director of the UW Interactive Data Lab, joins The Test Set to talk visualization research, responsible data science, and an experiment that used loading speed alone to manipulate what people found in a data set. We dive into Tableau's academic roots and where rational decisions quietly turn unethical.
