In an essay published in the Conversation, Daryl Cameron, Michael Inzlicht, and William Cunningham discuss the nature of empathy, specifically asking if empathy has limits. In the essay, which is part book review of Paul Bloom's Against Empathy, Michael and his co-authors suggest that limits to empathy are more apparent than real; these apparent limits are not built into empathy itself, but reflect the choices we make. These so-called limits, in other words, result from general trade-offs that people make as they balance some goals against others.
