One interesting trend we've noted recently is the proliferation of papers, articles and blog posts about data science that don't just tell the result--they include data and code that allow anyone to repeat the analysis. It's far from universal (for a timely counterpoint, read this article ), but we seem to be moving toward a new normal where data science conclusions are expected to be shown, not just told.
