I’m king of the world! You are too. We humans—all of us—get props for being the smartest Earthlings. And we’re not merely the smartest. No, we’re the only species worth writing home about; we’re the only truly worth building artificial intelligence to mimic. We’re the smart ones. The rest of the diversity of life may be rich in clever design, like well-engineered tools and gadgets, but they’re not designed to be intelligent. That’s for humans. Rationality and intelligence is something natural selection granted us.
But…what if our Homo sapiens intelligence is radically overrated? What if we’re smarter, but only quantitatively so, not qualitatively? What if many of our Earthly cousins are respectably intelligent after all? More intriguingly, what if there are systematic barriers that lead us to overestimate our true level of intelligence relative to that of others? And, although I won’t get into this here, what are the implications for the rights of chimpanzees, if the chasm between us and them is, instead, a slender fault line? That question has led to a recent movement to ban invasive research on chimpanzees in the U.S., a measure that the EU has already adopted.
Here I’ll discuss just two barriers, a little one and a big one, that conceal how smart we really are—or are not.
