The Logic of Failure

The Chernobyl atomic-plant explosion, observes Dorner, was entirely due to human error involving the breaking of safety rules by a team of experts who reinforced one another's puffed-up sense of competence. This German psychology professor believes people court failure through sloppy or ingrained mental habits, whether the mistakes involve cleaning dead fish out of a garden pool, adding rooms to a schoolhouse, launching economic development programs in Africa or forecasting oil prices or the scope of the AIDS epidemic. Things go wrong, according to Dorner, because we focus on just one element in a system complicated by interrelationships; we apply corrective measures too aggressively or too timidly; we ignore basic premises, overgeneralize, follow blind alleys, overlook potential side effects and narrowly extrapolate from the moment, basing our predictions of the future on those aspects of the present that bother or delight us the most. This ingenious manual will assist problem-solvers in all fields. (July)
