I didn't really read the article as positing any causal connection, but the warning about confirmation bias is reasnoable. It would be interesting to see more data on things like age, experience, demographics, etc. Despite the "correlation isn't causation" mantra, there are only 27 different possible causal graphs, so with enough data maybe we could get to the bottom of this Best Editor business. :P
