The elimination of wolves from Yellowstone National Park is a testament to the importance of protocols in contexts where problem management is a superior strategy to problem solving.
Wolves, bears, and other predators of sufficiently frightening size, pose serious problems to people. They’re both destructive and deadly. The obvious short-term solution is to just get rid of them. That’s what happened with the wolves in Yellowstone, whereas bears are typically managed in a more tolerant fashion.
We pay the costs of problem management and the costs of realized accidents, because the existing problem is actually a good one to have. In other words you want to have dynamic non-events, not pure non-events. Killing wolves to create a safe park is analogous to stopping highway construction to eliminate road worker accidents. Eventually it will usher in a worse problem
