It's kind of ironic that when you look at the evidence of intelligence and so on, a lot of it is anecdotal. A lot of it is, "Well, we saw this dolphin do this extraordinary thing," or, "We screwed up with our apparatus, and then the dolphins did this." And so it seems to me that the more we can actually watch them doing their thing, the better chance we'll have of making some sense of them.

Culture is not usually one of the criterion for personhood, but it has been argued that culture is sort of a medium for a lot of these criteria, such as empathy, and so on.

A bunch of individuals do the same thing because they learned from watching each other or somebody else. That's what we would call culture.

Psychologists would say that the only two important forms of social learning are imitation and teaching, and they will spend time trying to figure out if animals imitate or teach. Sometimes they find they do; sometimes they find they don't. And so that's kind of the level of controversy there. Biologists would include imitation and teaching and a range of other kinds of social learning. So we would call that culture, whereas the psychologist wouldn't.

I don't like to be dismissive of whales speaking possibilities. There is a pretty New Age-y, poorly thought set of ideas about this going around. I also think these animals benefit most from us staying out of their way. I think we learn the most by being as passive as we can, so those are my biases, and I'm sort of against it from that perspective.

When I'm out in the ocean and I watch a seabird, I think, "Oh, I probably I know what that seabird is doing" - and I don't study seabirds. And the same for the turtles and on and on. But with the whales, a lot of the time, I have no idea what they're doing, and they're the ones I study.
