It’s been a while since I’ve updated the plot of paper-length over time to check in on whether I have become more long-winded as I’ve gotten older. Short answer: I have not.
The blue line is the linear fit to all the data. It is basically flat, suggesting that I am about as concise as I have ever been.
The green line is the linear fit to just the coauthored papers. It has trended down, partly because I’ve had a few coauthored discussion notes in recent years.
