The AI bot has picked an answer for you. Here's how often it's bad.

We wanted to understand whether the AI was actually good at researching complex questions. So we set up an experiment with Microsoft's Bing chat, which includes citations for the answers its AI provides. The sources are linked in the text of its response and footnoted along the bottom with a shortened version of their addresses. We asked Bing 47 tough questions, then graded its more than 700 citations by tapping the expertise of 10 fellow Washington Post journalists.
