Better leads, fewer sales

Giving workers more promising customers sounds like a straightforward productivity improvement. At a Chinese online health-insurance brokerage, however, deploying AI voice agents to handle low-intent leads was followed by worse customer acquisition among human workers precisely where their opportunities improved most. In more than half a million outreach records, the probability that workers’ first three calls reached a high-intent lead rose by about 23 percentage points, while customer acquisition fell by about 5 percentage points. Both effects faded over the workday.

The researchers’ explanation is that better prospects made workers less willing to persist with the customer already on the line. Workers reallocated early leads more often and shortened those calls by about 13%. The preprint uses a regression-discontinuity-in-time design around the rollout, rather than a randomized experiment. Its practical message is nonetheless important: reallocating tasks between people and AI can change workers’ expectations and effort, not merely improve the raw material they receive.

Talk about a paper in public without overstating it: yours, one you are asked to comment on, or one you write about as a journalist.

  • Your paper: a draft release for your press office, the questions journalists will ask with what the paper lets you answer, the likely misreadings, a lay summary and a short thread.
  • Asked to comment: what the paper shows and does not, its strengths and weaknesses with their passages, and what would settle its main claim.
  • Writing about it as a journalist: reporting angles, the wording to check before publication, and the questions to ask the authors.
  • For everyone: findings with their passages checked word for word, the novelty set against the closest earlier papers, a hype check, figures with their credit, and researchers for an outside view who have not signed with the authors.
