Editor's note

Saul Cornell has studied the Second Amendment and the history of gun regulation for two decades. As he puts it, it’s an irony that both liberals and conservatives see the Second Amendment as a barrier to robust gun regulation. “These beliefs ignore an irrefutable historical truth,” Cornell argues in a 2017 piece that we are republishing because of its timeliness. “While the founding generation certainly esteemed the idea of an armed population, they were also ardent supporters of gun regulations.”

President Trump’s protectionist policies, such as his willingness to abandon multilateral trade deals like NAFTA, have sparked concern that he’s unraveling the U.S.’ legacy as champion of the liberal economic world order. But to Giulio Gallarotti, a professor of government at Wesleyan University, the idea that the U.S. ever was a free trade country is a myth. Even the supposedly free-trading Republicans have pushed protectionism alongside Democrats, and for good reason, says Gallarotti.

Using your index finger to point seems to be a part of human nature, like yawning or smiling. But when psychology researcher Kensy Cooperrider was in Papua New Guinea studying the indigenous Yupna, he noticed that they would often scrunch their noses – in what looked to outsiders like a gesture of disgust – to direct attention to something. Cooperrider tells the story of how he was able to document the prevalence of this nose-scrunching gesture – and how it adds a wrinkle to our understanding of universal human behavior.
