Knowledge Collapse: Chatbots Narrow What We Know

Researchers at the University of Copenhagen are warning that AI chatbots give us a narrow slice of knowledge—and that could be reshaping what society collectively knows. The new study, published September 2026, argues that heavy reliance on chatbots for answers cuts us off from diverse, fringe, and less-popular perspectives. That creates a feedback loop: the same dominant ideas get reinforced, while minority viewpoints fade. It's not a robot takeover story. It's subtler—and, the researchers say, harder to reverse.
