How we think about risk has very little to do with the actual, statistical chance of injury. If it did, few of us would ever climb behind the wheel in our cars. It was Jerry Kruk of Calgary who schooled me on the psychodynamics of fear a quarter century ago. He initially worked as a professional risk communicator for Canadian oil and gas projects, but later migrated to nuclear conflicts, specifically issues of radioactive waste disposal. Kruk emphasized two guiding principles: (1) when we can’t see, hear, smell or taste a threat we sensibly fear it, and (2) when we have little or no opportunity to forestall a danger or prevent our exposure, particularly if that risk is created by unknown or uncaring others, we respond with anger. Consequently, we think nothing of driving to the grocery due to the comforting presumption we can exercise control over our personal risk. This assurance is, of course, largely an illusion. More Americans have been killed on our roads and highways than in all our wars.
