A grizzly named Kobuk tests bear-resistant containers by trying to break into them. In his review of Alex Davies’s Kobuk the Destroyer, Gideon Lewis-Kraus uses this unlikely job to ask a serious question: who decides when a test is realistic enough to keep people safe?
- A container passes if it survives an hour of bear contact without a hole larger than a quarter inch. Even a test with a real bear depends on a human-chosen threshold.
- Crash-test dummies modeled on a historically “average” man have been poor stand-ins for women and children. A standardized test can miss the people it is meant to protect.
- Child-resistant pill bottles must defeat children but remain usable by older adults; otherwise a difficult cap may simply be left off.
- Early de Havilland Comet fuselage tests appeared reassuring, but the order of the tests had changed the cracks in the test pieces. Real aircraft failed far sooner.
The review is a defense of public expertise without pretending expertise is neutral. Engineers and regulators choose which risks count, whose bodies are represented, and how to balance safety against cost. A better simulation cannot make those choices for us; accountable people have to.
