Claim LD03-SL-C06 (v1.0)

In a six-month randomized trial of an integrated AI assistant across 66 firms and 7,137 knowledge workers, workers who used it spent about two fewer hours a week on email, but the authors detect no shift in the quantity or composition of workers' tasks from individual-level provision, and no change in time spent in meetings.

Research opportunities this claim motivates

What this claim leaves open for research. Each is a hypothesis about a gap, not a finding.

Does deploying AI to whole teams change the work that individual licences did not?Individual-level randomization across 66 firms: users spent about two fewer hours a week on email, with no detectable change in meeting time or task composition; the authors suggest that coordinated work may change only when colleagues adopt together.
Where does the time saved with generative AI go?Telemetry shows users spending about two fewer hours a week on email and less work outside regular hours, without tracing where the time went or linking it to output.
