Know This First: Risk Perception Is Always Irrational.

We need a post-Enlightenment definition of "rationality." Reason can take us only so far.

"IN 2011, THE CITY LEADERS of Calgary, Alberta, bowed to public pressure and ended fluoridation of the local drinking water, despite clear evidence that the benefits of fluoridation vastly outweigh its risks. A recent study found that second graders in Calgary now have 3.8 more cavities, on average, than a similar group did back in 2004-05, when the water was still being treated.

In West Virginia, legislators in favor of shrinking government recently passed a law allowing sale of unpasteurized milk, despite convincing evidence that raw milk is a vector for pathogens like Salmonella, E. coli, and Listeria. To celebrate, the bill’s sponsor shared some raw milk with his colleagues, several of whom got sick. The legislator says it was just coincidence.

Since the 2011 nuclear accident in Fukushima, Japan, fear of radiation has prompted thyroid cancer screening for all children in the prefecture. The levels of radiation to which kids had been exposed were too low to pose significant danger, and the sensitive ultrasound screening technique is well known to find abnormal cells in most people’s thyroids, though in nearly all cases those cells will never cause cancer. As a result of this unprecedented scrutiny for an infinitesimal risk, hundreds of kids have had their thyroids removed unnecessarily, with far-reaching health implications for the rest of their lives.

For anyone outside the emotions that produced these choices, it’s hard not to feel frustration at hearing about them. It’s hard not to call them ignorant, selfish, and irrational, or to label such behavior, as some do — often with more than a hint of derision — “science denialism.” It’s hard, but it’s necessary, because treating such decision-making as merely flawed thinking that can be rectified with cold hard reason flies in the face of compelling evidence to the contrary.

A really good piece for all of us, as we face a world where irrational emotions seem to be taking hold of more of our fellow humans every day.

It's strange seeing fear take over many people here and elsewhere, and yet this was nearly completely ignored.

Hmm.
