> I suspect that many pure science studies are relatively easier to reproduce since it's more about basic properties. Not necessarily true at all actually. To use an example, the field I work in requires that we grow our own semiconductor crystals. Different growth reactors in different universities producing nominally the exact same substance will result in sometimes vastly different properties of the end result when studied (usually due to minute trace impurities, or marginally different temperatures or flow rates during growth, or a host of other things–all of which need to be analysed and vetted–and this happens even if they're using growth reactors made by the same manufacturer!). It makes replication very difficult and often results in slow progress. And it's expensive too. So it's not just medicine that has that problem. Edit: I should add that obviously in the end it works out because these materials eventually make it into industry and into millions of devices. So it's ultimately reproducible. But that gap between first discovering a process or a mechanism or just something interesting and making it reproducible consistently enough and at a large enough scale for industry is just huge.
