Jason Collins reviews Tim Harford’s Adapt.

The concept of “normal accidents”, taken from a book of that title by Charles Perrow, is compelling. If a system is complex, things will go wrong. Safety measures that increase complexity can increase the potential for problems. As such, the question changes from “how do we stop accidents” to how do we mitigate their damage when they inevitably occur? This takes us to the concept of decoupling. When applied to the financial system, can financial institutions be decoupled from the broader system so that we can let them fail?

As I like to say, try to make the system easier to fix, not harder to break.
