Are you familiar with Judea Pearl's work regarding graphical analysis of causal problems? If not, he'd probably interest you. While he mostly falls in the category of "random academic papers" (and academic books), but he has also co-authored a very readable (and enjoyable) popular science book. A review of that book is here: http://bostonreview.net/science-nature/tim-maudlin-why-world. And a more technical overview of his graphical approach is here: https://www.timlrx.com/2018/08/09/applications-of-dags-in-ca....
