Another devastating hurricane season winds down in the Caribbean. As in previous years, we are left with haunting images of entire neighborhoods flattened, flooded streets, and ruined communities. This time it was the Bahamas, where damage was estimated at US $7 billion and at least 50 people were confirmed dead, with the possibility of many more fatalities yet to be discovered.

The introduction of any new system causes perturbations within the current operating environment, which in turn, create behavioral responses, some predictable, many not. As University of Michigan professor emeritus and student of system-human interactions John Leslie King observes “People find ways to use systems for their own benefit not anticipated by designers and developers. Their behavior might even be contradictory to hoped-for outcomes.”

“Change rides on the rails of what doesn’t change,” King notes, “including people being self-serving.”
