Kermack–McKendrick Epidemic SIR Infectious Disease Model - Metrics by Guy Lakeman

This is a simple SIR infectious diseases 3 stock model with Susceptibles, Infectives and Recovereds stocks.

From fighting lions (fight or flight) to fighting feedbacks in complex systems. A single person cutting the Gordian knot to the dynamic complexity of rubik's cube. Think of multiple players with multiple misperceptions of the faces on the cube and conflicting goals about what the desired solution is. Worse still, without an accepted framework we dont even know if it's a cube or another structure. See also policy resistance IM-697
