Researchers at Tel Aviv University, Warwick, ESSEC and Hebrew University report that everyday search and chat tools, which rank results by popularity, push people who work separately toward the same ideas. In two experiments they replaced the ranking with one that surfaces unfamiliar, varied material, and ideas were judged more creative. The gain was largest for people with deep knowledge of the subject; novices benefited far less.

What changed

Search and assistant tools rank results by popularity and relevance, drawing on a user's own history.

What it unlocks

Prompting or configuring search and chat tools to surface unfamiliar, cross-domain material during early-stage idea generation, and clustering a team's ideas to see how narrow they are.

  • 104 lab participants
  • 245 field participants
  • 14% more creative ideas (lab)
  • experts: 5 idea clusters vs 1-2
