Gabrielle Bauer, a Toronto-based medical writer, has just published one of the most concise explanations of what’s wrong with the precautionary principle that I have ever read. The precautionary principle, you will recall, generally refers to public policies that limit or even prohibit trial-and-error experimentation and risk-taking. Innovations are restricted until their creators can prove that they will not cause any harms or disruptions. In an essay for The New Atlantis entitled, “Danger: Caution Ahead,” Bauer uses the world’s recent experiences with COVID lockdowns as the backdrop for how society can sometimes take extreme caution too far, and create more serious dangers in the process. “The phrase ‘abundance of caution’ captures the precautionary principle in a more literary way,” Bauer notes. Indeed, another way to look at it is through the prism of the old saying, “better to be safe than sorry.” The problem, she correctly observes, is that, “extreme caution comes at a cost.” This is exactly right and it points to the profound trade-offs associated with precautionary principle thinking in practice.
In my own writing about the problems associated with the precautionary principle (see list of essays at bottom), I often like to paraphrase an ancient nugget of wisdom from St. Thomas Aquinas, who once noted in his Summa Theologica that, if the highest aim of a captain were merely to preserve their ship, then they would simply keep it in port forever. Of course, that is not the only goal of a captain has. The safety of the vessel and the crew is essential, of course, but captains brave the high seas because there are good reasons to take such risks. Most obviously, it might be how they make their living. But historically, captains have also taken to the seas as pioneering explorers, researchers, or even just thrill-seekers.
This was equally true when humans first decided to take to the air in balloons, blimps, airplanes, and rockets. A strict application of the precautionary principle would have instead told us we should keep our feet on the ground. Better to be safe than sorry! Thankfully, many brave souls ignored that advice and took the heavens in the spirit of exploration and adventure. As Wilbur Wright once famously said, “If you are looking for perfect safety, you would do well to sit on a fence and watch the birds.” Needless to say, humans would have never mastered the skies if the Wright brothers (and many others) had not gotten off the fence and taken the risks they did.
