Quite possible -- Robins was pointed out to me as one of the pioneers by Sander Greenland, around 2008 or so? I'm more of an experimental/clinical statistician

Quite possible -- Robins was pointed out to me as one of the pioneers by Sander Greenland, around 2008 or so? I'm more of an experimental/clinical statistician at this point. The work I did with propensity scoring and doubly robust estimation convinced me that shrinkage was a less-bad approach for the things I needed to do. YMMV.
