We don't just respond to things as we see them, or feel them, or hear them. Rather, our response is conditioned on our beliefs, about what they really are, what they came from, what they're made of, what their hidden nature is.

If you like somebody, they look better to you. This is why spouses in happy marriages tend to think that their husband or wife looks much better than anyone else thinks that they do.

We are constituted so that simple acts of kindness, such as giving to charity or expressing gratitude, have a positive effect on our long-term moods. The key to the happy life, it seems, is the good life: a life with sustained relationships, challenging work, and connections to community.

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

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'm really interested in the pleasure we get from stories and the pleasure we get from movies, and certainly the pleasure we get from virtual experiences. My complaint is against empathy as a moral guide. But as a source of pleasure, it can't be beat.

I think there's some evidence that we're empathic by nature. There is some evidence from studies of babies and young children that they resonate with the pain of others, and there's some work by Frans de Waal that other primates also resonate with the pain of others.
