While I am still a great fan of Kahneman's best seller "Thinking, fast and slow" (2011), here are refreshing views about the pervasive presentation of making processes based on two orthogonal systems: type I (fast, unconscious, automatic, error prone) vs. type II (slow, conscious, costly, reliable).
