Prevention of fear logically involved efforts to reduce danger. Emotion-or more properly, emotion prevention-lay at the heart of a growing intolerance of risks: here was a key link between the changing emotional culture and new policies and behaviors. Legal and corporate factors joined in the resultant attack in the unpredictable and the accidental. The result, however-since there were limits to accident prevention-could ironically increase emotional anxiety and heighten a desire to seek specific responsibility for mischance. Redefinition of risk, in a climate of emotional reassessment, helped translate aversion to fear into a variety of public and international policies.
