(p. 247) All versions of the Precautionary Principle hold this axiom in common: A technology must be shown to do no harm before it is embraced. It must be proven to be safe before it is disseminated. If it cannot be proven safe, it should be prohibited, curtailed, modified, junked, or ignored. In other words, the first response to a new idea should be inaction until its safety is established. When an innovation appears, we should pause. Only after a new technology has been deemed okay by the certainty of science should we try to live with it.
On the surface, this approach seems reasonable and prudent. Harm must be anticipated and preempted. Better safe than sorry. Unfortunately, the Precautionary Principle works better in theory than in practice. “The precautionary principle is very, very good for one thing–stopping technological progress,” says philosopher and consultant Max More. Cass R. Sunstein, who devoted a book to debunking the principle, says, “We must challenge the Precautionary Principle not because it leads in bad directions, but because read for all it is worth, it leads in no direction at all.”
