My website ran into this issue. I came to a conclusion that was like 80% correct, but it was 20% missing. Heck, I think I solved that 20%, and I found an additional 20% I feel is missing.

Anyway, there are a few reasons to continue solving. First, its good to grow knowledge and make correct decisions. Second, someone smart will call you out on it at some point, you will not be able to escape it.

I am casual, so I have no reason not to keep pursuing it, no PhD or grants needed. Heck, my audience loves when I dive deeper than before. My website produces science and I have quite a few academics reading it. Wonder why this doesnt apply in Academia?
