The Paradox of Unanimity

» March 8th, 2016

 

In a paper about to be published in The Proceedings of the Royal Society, a team of researchers identifies something they call the “paradox of unanimity.” If you’ve ever smelled a rat when everyone else is celebrating an idea then this paradox is for you. While unanimous agreement (or something close to it) might suggest that a particular claim is right, the researchers, led by Lachlan J. Gunn, an engineer at the University of Adelaide in Australia, found the opposite to be true. Rather than confirming truth, unanimity indicates that something went wrong, that a “systemic failure” undermined popular judgment, that the confidence of the crowd has been skewed by bias.

As it’s currently framed, the paradox applies primarily to criminal justice concerns—police line-ups and the like. But it also has implications for food and agriculture. Few fields of popular interest have cultivated a wider array of glib axioms of empowerment than food: genetically modified organisms are bad, local is better, you shouldn’t eat food your grandmother wouldn’t eat, and so on. In the context of Main Street foodie wisdom, these claims enjoy something close to unanimity. But, for all their support, none comes closer to the unanimity quotient than the gilded assertion that organic food is food grown without pesticides.
