There doesn't seem to be much reason to challenge the assumption: humans aren't good at solving any problems that we know to be uncomputable (e.g. the halting problem). Sure, it's a thing you could investigate, but the explanation for why it's not a popular topic is that it doesn't seem like a fruitful area of research.

Also, personally what my mind is doing doesn't feel like it's invoking an oracle for my problem solving. Generally when the search space for a problem that I'm solving increases I experience the kinds of blowups in the difficulty that would arise from me following an algorithm. Now, not everybody is the same. Do you feel like your problem solving calls an oracle?
