Instructions for reproduction are mandatory already. That said, you probably can&#x27;t pick up any paper and reproduce the experiments exactly without asking the authors a question or two, at least in biology.<p>Systems are getting increasingly complex as well. In my lab, it literally takes several weeks for people to learn how to do our assay, and that&#x27;s with constant feedback from an experienced user. Every step is published but that still doesn&#x27;t help when things don&#x27;t go according to plan. Also, not every lab has the same equipment. Even if we provided free training, a lab would still need to drop $300k to get all the machines required, which are not common.<p>Not every result is worth reproducing either. If someone publishes a paper that shows several lines of evidence for the same thing and they&#x27;ve done all reasonable controls, and it doesn&#x27;t disagree with any existing models, why would you reproduce that? Outside of deliberate fraud, it&#x27;s a pretty solid bet that it&#x27;s true, and you can save enormous amounts of time and money by proceeding to build off of it instead of reproducing it first. And that&#x27;s really what it comes down to: no one&#x27;s paying you to do this kind of work. Governments would have to fund it, because you&#x27;re fundamentally asking for twice as much work to be done, which will cost twice as much money (and time).<p>But take heart: when someone DOES make an outrageous claim, it&#x27;s very common for labs to try to reproduce it (or really, disprove it).
