These observations bring us back to a complaint I’ve made before—empathy is innumerate and biased. Hearing that my child has been mildly harmed is far more moving for me than hearing about the horrific death of thousands of strangers. This might be a fine attitude for a father—we’ll return to that question at the end of the next chapter—but it’s a poor attitude for a policy maker and a poor moral guide to our treatment of strangers.
