When AI helps until the task changes

It shows that a tool's competence is uneven in ways that are hard to see from inside a task, which makes knowing where the tool fails a form of experience in its own right.

A preregistered field experiment with several hundred management consultants. On tasks inside the model's capability, consultants using GPT-4 finished more tasks, faster, and at higher rated quality. On a task designed to sit outside that capability, those using the tool were more likely to get the answer wrong.

What the source supports

  • AI capability is uneven across tasks that look similar in difficulty. The authors call this the jagged frontier.
  • For tasks inside the frontier, consultants with the tool performed measurably better on speed and rated quality.
  • For a task outside the frontier, tool use was associated with worse accuracy.

What the source does not support

  • That the frontier is fixed. The authors describe it as moving and hard to see from the inside.
  • That professionals can reliably tell in advance which side of the frontier a task sits on.
  • Any general claim about consulting careers, hiring, or the value of experience over time.

What Sougata is doing with it

Sougata uses this to support one specific point: the segment of a workflow that a tool handles well is not the whole workflow, and knowing where the tool fails is itself a form of experienced judgment. The framing of workflow segment versus judgment is Sougata's, not the paper's.
