Imagine a smart computer brain, called an LLM, that learns by finding patterns in words. But here’s the spooky part: if many websites, even bad ones, keep repeating a false story, the LLM starts to believe it’s true, just because it sees the pattern so often. This can make the computer confidently tell you wrong information, like a parrot repeating a lie it heard a lot. It creates a scary echo chamber where mistakes can grow and spread, making it hard to find real facts. So, these powerful AI brains can sometimes be tricked into thinking lies are the truth, especially if those lies are repeated over and over.
