What Does "Evidence-Based" Actually Mean for AI?

This episode has been a long time coming, as I finish up a busy semester.One of the things consuming most of my attention lately is a research grant I’m running with a colleague in computer engineering. Students are building structured chatbots for disaster communication, then assessing and documenting how those systems actually perform.More on that soon. But a question keeps surfacing in that work: how do we actually evaluate an AI system? What counts as evidence? And how do we measure it in ways that are meaningful, not just convenient?I’m Lance Cummings.
