AI Gives Wrong Answers Sometimes: Here Is Why
Have you ever asked an AI chatbot a question and got a completely wrong answer?
It sounded confident. It was well written. But it was just plain wrong.
This problem has a name. It is called hallucination. And it happens because most AI models only know what they were trained on.
They have a knowledge cutoff date and cannot access new information or private company documents.
So when you ask something they do not know, they fill in the gap. Sometimes that means making something up.
RAG was built to fix this exact problem.
And in 2026, it has become one of the most important skills in the entire AI field.
