You're wrong. What you say - that we conclude anything if not everything was taken into consideration - is undoubtedly true for mathematical meaning of "conclude". Mathematicians, computer scientists and a few others, like theoretic physicists, have a luxury of using law of excluded middle, which Sherlock Holmes also used. The famous detective states that if you eliminate everything that is impossible, whatever remains is true, even if it sounds improbable. All the people who use this law do so because their work is about some kind of model, which can be wholly known. However, if you have a misfortune of working in the real world - like nearly everyone - then you can't apply this law. This means that you won't ever get a proof in a mathematical sense. You won't ever be completely certain - you can be convinced beyond reasonable doubt, but that's all. So when we talk about how biologists are just grant hunters because someone couldn't reproduce their experiments we need to take this into account. I don't know, but if I had to guess I'd say that nobody ever expected these experiments to be 100% accurate, 100% reproducible or 100% true. I think they are treated as a data point, some input to think of, and not definite truth. But I may be completely wrong here, of course.
