Prompting for Truth: Techniques to Keep Your AI Honest

Think of ChatGPT as the most brilliant, well-read, and eager-to-please intern you've ever met. It's absorbed more information than anyone in history, but its primary goal is to give you a confident, coherent answer. Sometimes, to achieve that, it will fill in the gaps with 'plausible' information that is, in reality, completely made up. This is a hallucination.
