Verifying information and critical thinking when using ChatGPT

ChatGPT is a powerful tool that generates text-based answers from a vast dataset, but it is not a database of facts. It produces plausibly sounding responses (answers that seem convincing and logical, even if they may be inaccurate or fabricated) by relying on language patterns. This means that even when answers sound confident, they may still be false or incomplete. Reviews show that the model can make mistakes in simple questions and continue making them even after corrections. This means its conclusions should be treated as suggestions rather than absolute truth. That is why it is important for users to follow safety rules and verify the information.
