I have two teenage sons, and they're both surviving, thriving, and having a great time, and they're always on social media.

Traditionally, psychology has been the study of two populations: university freshmen and white rats.

When I write I'll sometimes say things which are somewhat controversial - not because I'm seeking out controversy for its own sake, but if I don't have anything to say which is different, why am I bothering to write stuff down in the first place?

It has been a period where people have been far nicer to one another in every possible way. I'm not saying it's because we're dropping our empathy that we're nicer to each other, just that the drop doesn't seem to be causing any harm.

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.

My brother is severely autistic, so when I was a kid I spent a lot of time as a teenager in camps and programs for autistic kids. When I went to McGill as an undergraduate, I figured I'd be a therapist working with these kids. The truth is, and I knew this even back then, I'm just not good at this. I'm too empathic to do this sort of thing.

Even the charities I give to are related to things that touch my life, like the Special Olympics. I'm not fully rational; I'm swayed by my biases and my emotions.
