From the hash-bound evidence releases
Recorded claims
Each claim states what the inspected source says, at the recorded location—bounded by its scope and graded by its confidence. Nothing here is a synthesis across works.
In a randomized experiment with 453 college-educated professionals completing occupation-specific writing tasks, ChatGPT access reduced completion time by about 40% and increased evaluated output quality by about 18%.
Scope: Short professional writing tasks; task productivity, not realized firm performance.
Benefits were larger for initially lower-performing participants, compressing performance inequality on the studied tasks, but the experiment did not test whether this convergence persists after workers stop using the tool or across interdependent workflows.
Scope: Experimental task performance and the study window only.
Structured relationships

Boundaries
Limitations & independence
Recorded at coding time, carried with the work forever. A claim without its limits is not evidence.
Recorded limitations
- 453 college-educated professionals on short writing tasks
- Participants and evaluators operated outside a continuing organization
- No long-run learning, wage, or firm outcome
- Early ChatGPT model
Source independence
Independent academic randomized online experiment; simulated professional tasks rather than embedded firm outcomes.
