When you think about yourself -- at least while doing so inside the narrow metal tube of a machine that uses functional magnetic resonance imaging (fMRI) -- a certain part of your brain, called the medial prefrontal cortex, or MPFC, will light up like Times Square on New Year’s Eve. If you think about a family member, the MPFC will still light up, though less robustly. And if you think about the people whom you feel you have no connection to -- like, say, the inhabitants of the South Asian Island nation of the Maldives, which will likely one day be eased by climate-change-driven sea level rise -- the MPFC will light up even less.

You don’t need a $3 million MRI machine to know that human beings are self-centered creatures. But as Jane McGonigal,, the research director of the Institute for the Future, noted in a 2017 article for ‘Slate,’ what’s strange is that if you think about your own self in the future, you’ll see less activation in the MPFC than when you imagine your present self. The further out in time you imagine that self, the weaker the activation is. As McGonigal writes: “Your brain acts as if your future self is someone you don’t know very well and, frankly, someone you don’t care about.” An if you view our own selves in the future as virtual strangers, how much less do we care about the lives of generations you to be born? ~ Page 157
