There are a couple of issues with the research though that I have questions about. One is that, as most of us who program know, the syntax is just one part of it. The tools, the community, the documentation, the libraries and platforms, and so on all factor into our decisions and productivity when programming.
A second issue is more about the research. A/B tests and randomized trials are all great and useful. But that also is not enough. What is the theory or theories you are testing? I wouldn't choose a keyword over another just because one short, lab-based study showed a p-value under .05. You also need to do other styles of research to get a richer picture of what is going on, such as design-based research and qualitative research methods.
