Also pertinent here is the Alexander Pope quotation included in Franklin's autobiography: "Men must be taught as if you taught them not, And things unknown proposed as things forgot." You may know the answer to the problem someone else is going through. You may know that their approach is utter garbage and that they are clueless as to what they are doing. But rather than saying so outright, which will likely come across as offensive, it seems better to phrase things in such a way as that they will come to see the better solution for themselves. They might not even realize the role you played in that, nor credit you for the insight. But they will have learned something, improved their work, and didn't feel insulted. In my experience, it's a route worth trying, anyway.
