A METR note shows that when workers shift towards the tasks AI speeds up, time saved measured on the new mix of tasks overstates the value gained, which lies between the speedup on the old task mix and on the new one under the note's assumptions; the authors suggest this may help explain why reported gains exceed aggregate data.

Claim LD03-SL-C13 (v1.0)

Provenance and status

Claim type: Interpretation
Publication status: Eligible for publication, with a qualifier

Does not license: Any empirical estimate of AI's effect
Limitations: A theoretical note, not peer reviewed; the bounds assume workers allocate time optimally with accurate beliefs, and the authors note that in practice they could reverse
