““For the psychologist Paul Bloom, this is a huge downside. Empathy, he argues, focuses our attention on single individuals, leading us to become both parochial and insensitive to scale.62 As Bertrand Russell is often reported to have said, “The mark of a civilized man is the capacity to read a column of numbers and weep,”63 but few of us are capable of truly feeling statistics in this way. If only we could be moved more by our heads than our hearts, we could do a lot more good. And yet the incentives to show empathy and spontaneous compassion are overwhelming. Think about it: Which kind of people are likely to make better friends, coworkers, and spouses—“calculators” who manage their generosity with a spreadsheet, or “emoters” who simply can’t help being moved to help people right in front of them? Sensing that emoters, rather than calculators, are generally preferred as allies, our brains are keen to advertise that we are emoters. Spontaneous generosity may not be the most effective way to improve human welfare on a global scale, but it’s effective where our ancestors needed it to be: at finding mates and building a strong network of allies.””
