Someone has now pointed to some data in the study that isn't stratified by education level: https://news.ycombinator.com/item?id=35518556 https://news.ycombinator.com/item?id=35518556 If I'm reading table S11 correctly, ICAR scores were 0.016 standard deviations lower on 2018 than in 2011. I don't know whether the researchers chose those years for some specific reason, or if those years were the only ones available. It would be interesting to know whether the intervening years show a steady decline, or something more like a random walk.
