>what's the explanation for forgetting something 1 second after thinking of it?
The brain got a pruning mechanism so you don't remember pointless minutia, that's probably a useful feature.

how would the brain know it's important or not?

>>711
It doesn't, it's probably just very clever heuristics. While your brain would technically be capable of perfectly reciting a book you once read word for word, it's not letting you decide whether you want to remember. There's people with eidetic memory with that kind of recollection, but they can't turn it off.
