Study Finds AI Chatbots Provide Less Diverse Information Than Google Searches
A University of Copenhagen-led study warns that AI chatbots like ChatGPT and Gemini provide users with a narrower range of information compared to traditional Google searches. Testing 27 large language models across 155 topics, researchers found chatbots deliver more uniform responses, potentially causing a 'knowledge collapse' by limiting exposure to diverse facts and perspectives. Even the most varied model, OpenAI's GPT-5, offered nearly 19% less diverse information than Google, raising concerns about the long-term impact on knowledge access.
