How does the government or a business plan for an unimaginable disaster-a meltdown at a nuclear power plant, a gigantic oil spill, or a nuclear attack? Lee Clarke examines actual attempts to "prepare" for these catastrophes and finds that the policies adopted by corporations and government agencies are fundamentally rhetorical: the plans have no chance to succeed, yet they serve both the organizations and the public as symbols of control, order, and stability. These "fantasy documents" attempt to inspire confidence in organizations, but for Clarke they are disturbing persuasions, soothing our perception that we ultimately cannot control our own technological advances.

For example, Clarke studies corporations' plans for cleaning up oil spills in Prince William Sound prior to the Exxon Valdez debacle, and he finds that the accepted strategies were not just unrealistic but completely untenable. Although different organizations were required to have a cleanup plan for huge spills in the sound, a really massive spill was unprecedented, and the accepted policy was little more than a patchwork of guesses based on (mostly unsuccessful) cleanups after smaller accidents.

While we are increasingly skeptical of big organizations, we still have no choice but to depend on them for protection from large-scale disasters. We expect their specialists to tell the truth, and yet, as Clarke points out, reassuring rhetoric (under the guise of expert prediction) may have no basis in fact or truth because no such basis is attainable.

In uncovering the dangers of planning when implementation is a fantasy, Clarke concludes that society would be safer, smarter, and fairer if organizations could admit their limitations.

"An incursion into new territory written with insight and flair, Clarke's book achieves a revolution in understanding plans as an organizational activity-how they come about, why they go awry, and the often-disastrous disconnect between plans and an organization's ability to carry them out. A book that will fascinate general readers, administrators, organization theorists, and disaster buffs, Mission Improbable stands as a valuable companion volume to Pressman and Wildavsky's Implementation."—Diane Vaughan, author of The Challenger Launch Decision

Al Qaeda detonates a nuclear weapon in Times Square during rush hour, wiping out half of Manhattan and killing 500,000 people. A virulent strain of bird flu jumps to humans in Thailand, sweeps across Asia, and claims more than fifty million lives. A single freight car of chlorine derails on the outskirts of Los Angeles, spilling its contents and killing seven million. An asteroid ten kilometers wide slams into the Atlantic Ocean, unleashing a tsunami that renders life on the planet as we know it extinct.

We consider the few who live in fear of such scenarios to be alarmist or even paranoid. But Worst Cases shows that such individuals—like Cassandra foreseeing the fall of Troy—are more reasonable and prescient than you might think. In this book, Lee Clarke surveys the full range of possible catastrophes that animate and dominate the popular imagination, from toxic spills and terrorism to plane crashes and pandemics. Along the way, he explores how the ubiquity of worst cases in everyday life has rendered them ordinary and mundane. Fear and dread, Clarke argues, have actually become too rare: only when the public has more substantial information and more credible warnings will it take worst cases as seriously as it should.

A timely and necessary look into how we think about the unthinkable, Worst Cases will be must reading for anyone attuned to our current climate of threat and fear.
