Over the past three decades, the Precautionary Principle has become popular in discussions of public policy, especially in relation to health and environmental policy. Though there are a number of different versions of the principle, the genesis of the idea is that it is better to be safe than sorry. In terms of public policy, proponents of the PP argue that being safe means that, if there is a possibility of harm from a new activity or novel technology, even if (...) the scientific evidence concerning the harm is absent or uncertain, precautionary actions should be taken. In one version or another, the PP has been incorporated into a number of laws and treaties. Yet arguments for the PP are unconvincing, the PP itself is vague and when enacted in law, results in arbitrary regulations that pose a threat to human welfare. As a result, the PP should be rejected as a basis for public policy. (shrink)
