We often think we know more than we really do—but what is knowledge, exactly? In this episode of The Thursday Thought Experiment, we explore the classical definition of knowledge as “justified true belief,” and why it isn’t enough.

Along the way, we’ll look at reliabilism, safety theory, and the challenge of separating lucky guesses from genuine understanding.

Join us as we ask: what does it take to move from mere belief to real knowledge?
