I find your lack of reproducibility… disturbing

 “The rush to celebrate “eureka” moments often overshadows a rather mundane activity on which science depends: repetition.”

After reading several articles on the possible crisis of reproducibility, I find that these articles seem to be written in a way that suggests no one currently attempts to replicate experiments within their lab before publishing an exciting result. To me, the idea of publishing without replication sounds careless and is not a quality I anticipate in most scientists. Certainly, the numbers they report on individuals’ inabilities to repeat various experiments are staggering. Like these individuals, I have failed to obtain the same result from repeating an experiment. That’s just science. Shit happens. However, among the seven scientific mentors that I have had the pleasure of working under, I have never gotten the sense that scientists tend to publish without verifying results. This may be a small sample size, but it is these mentors and others that instilled a sense of the importance of replication, both with the same experiment and with other methods, in myself.

In my lab, obtaining an exciting result is met with intense interest… and skepticism. From the moment we find such a result, we begin working to falsify it. This includes both replication of the initial experiment as well as finding ways to show the same finding using other methods, all done with plenty of controls. If these attempts prove futile, then we become truly excited. We do this because my PI would sooner see us spend more time to be confident in our findings than have to retract a paper after its publication. Personally, I am a huge proponent of showing the same result using different techniques. Perhaps this opinion is a side effect of my own paranoia but, in science, we sometimes forget that our techniques are often prone to error when an exciting result appears. Further, this method for improving data reproduction was not mentioned once in the four articles I read on the subject of the reproducibility crisis. Yes, this method requires time and resources, but so do all the other methods proposed in these articles. A few extra resources to offset the supposed $28 billion wasted on non-reproducible results is a small price to pay.
