> The significance of Gettier problems as we investigated it is the exposure of an entirely _wrong_ mode of philosophy: philosophizing by intuition. Ultimately, the reason Gettier problems are significant is because for philosophers, the textbook Gettier problem works because _for philosophers_ the problem captures their intuitions of knowledge, and then proves the case of knowledge fails.

And to concretely tie this directly back to software[0]:

Intuition is a wonderful thing. Once you have acquired knowledge and experience in an area, you start getting gut-level feelings about the right way to handle certain situations or problems, and these intuitions can save large amounts of time and effort. However, it’s easy to become overconfident and assume that your intuition is infallible, and this can lead to mistakes.

One area where people frequently misuse their intuition is performance analysis. Developers often jump to conclusions about the source of a performance problem and run off to make changes without making measurements to be sure that the intuition is correct (“Of course it’s the xyz that is slow”). More often than not they are wrong, and the change ends up making the system more complicated without fixing the problem.
