Study: question order affects AI diagnostic accuracy; final accuracy doesn't measure info seeking

A study by Harvard Medical School, Broad Institute, Kempner Institute, and Google DeepMind formalizes multi-turn information seeking as a k-underspecified constraint satisfaction problem, introducing MT-INFOSEEK benchmark with 5,251 problems and 9,006 tasks across math, logic, gene regulation, clinical decision pathways, and 20 Questions. Key findings: models detect missing info; question order matters—wrong first question reduces final accuracy even if all variables are eventually obtained; final accuracy doesn't measure information seeking—models may produce plausible answers without sufficient info.
