When people want to inspire you to turn against some group of people, they'll often use empathy. When Obama wanted to bomb Syria, he drew our attention to the victims of chemical warfare. And in both of the Iraq wars, politicians said, "Look at the horrific things that are happening." I'm not a pacifist. I think the suffering of innocent people can be a catalyst for moral action. But empathy puts too much weight on the scale in favor of war. Empathy can really lead to violence.

Empty heads, cognitive science has taught us, learn nothing. The powerful cultural and personal flexibility of our species is owed at least in part to our starting off so well-informed; we are good learners because we know what to pay attention to and what questions are the right ones to ask.

I have huge admiration for people who think like the effective altruist, who try to rationally think about how they can change the world for the better, and who try not to be swayed by irrational considerations, such as skin color or whether or not someone lives in the same neighborhood.

I kind of like social media, and I like hearing from people. I don't like the ugly stuff, but there are some people - smart people - who have a very different perspective, and I'll get a backlash from them. And this isn't necessarily a bad thing.

It's hard to pull apart empathy from compassion. What is really clear is that we innately care for other people at least to some extent.

I argue that we should be kind, we should be compassionate, and we should definitely be reasonable and rational, but that empathy leads us astray.

Stories turn anonymous strangers into people who matter.
