I'm unsure what to think of this piece. I suspect that Gelman is right that there is a bias here. However, I also think most of us don't practice enough. I'll use writing, though other examples would serve equally well. I don't write that well, but my best writing is much better than my worst. When I write badly, I don't think it's because writing is hard, but because I didn't put in the effort. We have the Joel test for software companies. Scoring high doesn't make you world class, but scoring 0 is a bad sign. Think of the analogous test for writing. Do you read your work out loud? Do you solicit feedback for clarity? Do you look for your weaknesses as a writer? How much editing do you do?
