I suspect they're more intelligent than that. By, like, a lot.

When I was a teenager, I took a rowboat out onto what was then called Scammon's Lagoon, in Baja California, where the Grey whales raise their young. A mother whale -- several times the size of our boat -- and her calf approached. The calf was curious but cautious, so the mother nudged it into approaching the boat, close enough that we could reach over and rub its nose, which everyone on the boat did in turns.

What did the whales get out of this? Certainly nothing tangible -- nobody was feeding them or anything like that. But if you've ever rubbed a wild baby whale's nose while looking at it in the eyes -- and experienced the emotional connection which results -- then you will be forever incapable of hostility, apathy, or utilitarian thinking about whales.

I'm certain the mother whale knew what she was doing. She was recruiting us to her side. MUCH more effective, in the long term, than merely running away.

So are we (supposedly), yet we collaborate and hang out with other people.
