The Value of Knowledge and Epistemic Luck

Quick fact

In a famous case, a person believes the CFO's name is 'Mr. Nogot' based on strong evidence, but the name is actually shared by another person in the office—making the belief true by sheer coincidence rather than by justification. This shows that justified true belief can still fail to be knowledge when epistemic luck is involved.

Why this is interesting

We usually think knowledge is better than a lucky guess. But what if even a fully justified true belief turns out to be lucky—and is that still knowledge?
