TL;DR - the authors of this paper (http://janvitek.org/pubs/toplas19.pdf http://janvitek.org/pubs/toplas19.pdf) tried for 6 months to replicate the results of previous research that showed certain programming languages were associated with fewer defects. They could not replicate the results (or I guess only replicate very small differences in outcomes), and identified numerous statistical and methodological (is that a word?) issues with the previous results. What's really interesting for me is the in-depth discussion about why the previous results could not be replicated, and best practices for moving forward to achieve reproducible results in general with this kind of research.
