🧩 Human-AI Teams

Abstract

Tests whether AI explanations help human-AI teams exceed the performance of either alone. Surprisingly, explanations that increase understanding do not always improve team performance — and can even hurt it by inducing over-reliance.

Key Findings

  • AI explanations improve human understanding but not necessarily team performance
  • Explanations can induce over-reliance when the AI is wrong
  • Complementary performance requires humans to know when to override the AI
