Teaching AI models to say ‘I’m not sure’ in cases of calibration errors

Confidence is persuasive. In artificial intelligence systems, it is often misleading.

Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have now traced that overconfidence …

AI swarms could hijack democracy without anyone noticing

AI-powered personas are becoming so realistic that they can infiltrate online communities and subtly steer public opinion. Unlike traditional bots, they adapt, coordinate, and refine their messaging at a massive scale, creating a false sense of consensus. Early warning signs—like deepfakes and fake news networks—have already appeared in global elections. Researchers warn that the next …
