Editor’s Summary: This article considers the bold claim that politicians from different parties really “all sound the same”. It trains an AI model on 20+ years of Finnish parliamentary speeches and compares its guesses about affiliation with that of 438 human readers. It turns out that the system is ‘better’ at telling parties apart. Humans apparently rely on conversations on economy and immigration to determine their opinions on political speeches. The AI also picks up patterns and quirks, which apparently a human would never figure out.
