In particular, inductive reasoning starts reaching its limits when observability, reproducibility, and complexity are issues. Sometimes we invent things to push those boundaries (calculus, computers, drug trials on animals), but some complexity can be proven to be incalculable. And some results (The Milgram Experiment) are too terrible to reproduce to be worth the scientific knowledge they could offer. I think there's plenty we should be eager to learn, but I think it's realistic to think there are areas where "less incomplete understanding" is the best we can hope for.
