When is precaution the best design solution?
A series of interesting articles came up recently in the Guardian and presented differing viewpoints on the precautionary principle, which puts many policymakers in a conundrum especially while planning for the long-term. In one of the articles Andy Stirling1 highlights as to why the precautionary principle matters. Stirling suggests that it is important to consider various future policy options instead of using precaution as an excuse for not taking any action. He argues that doing the same requires “understanding, rather than denial, of the real nature of uncertainty”. He highlights that taking precaution suggests that we are not only considering risk but also uncertainty, whether it is owing to lack of empirical evidence, inherent complexity of an issue or system, differing scientific views, element of surprise etc. Stirling argues that the imminent pressure from policymakers about ‘justifying a decision’ makes scientists continue to ‘micro-correct’ their results and offering “risk-based prescriptions” by overlooking the precautionary principle that provides room to address uncertainty.
Tracey Brown2 on the other hand suggests that the precautionary principle “stops innovation in its tracks”. She argues that the principle makes us stop or ban something supposedly harmful and subsequent believe that we are safe from harm. She argues that the precautionary principle is built on our present knowledge of the world, which includes our present doubts, fears and biases. So in resisting change for the fear of the unknown we are resisting deviations from the status quo even if that itself is a huge problem that needs urgent attention, Brown argues. She says that we need big changes and some risks for pressing problems such as food [...]
