Columnist Virginia Heffernan argues that President Donald Trump lacks something that makes him feel empathy. She says, "Mirror neurons have been directly observed only in monkeys, though there is evidence they exist in humans too. And in 2013, the neuroscientist V.S. Ramachandran went so far as to claim that mirror neurons are what make us human and civilize us, helping us to imagine, and even experience, other people’s interior states. ... But perhaps neural attunement is not available to everyone."
