As someone who is prominent in trying to promote open, reproducible ways of working, I'm often asked how much time this it takes. Many scientists are worried about doing anything that might slow down their production of research papers. In our competitive times, when a glittering CV is needed to be employable, why would anyone want to act in a way that would be equivalent to running a race with one's shoelaces tied together?
This is a valid concern. If you know that your data and scripts are going to be open so that anyone could check your results, you turn into an obsessive. I used to pride myself on being careful and thorough, but I now realise I wasn't. I check and re-check everything – and the horrifying truth is that I still find errors in my work.
I started to wonder if my brain was beginning to rot, but I have found that others have the same experience, and indeed it was engagingly described by David Donoho (1), who talked about 'the ubiquity of error'. There's no doubt that, once you realise just how error-prone we all are, you will have to slow down to check everything, and your rate of productivity will decline.
