How to Safely Think in Systems
The authors number one recommended book is ~166 pages in total. I skimmed through and it's mostly pictures. The blog also contained no data. This is all completely fine, but it rubs me the wrong way when things are posed as scientific or rigorous, but are mostly subjective opinion pieces. I like to see what "thinking in systems" gets me with real evidence. I appreciate they took the time to create and share this though.
