Humans do a lot of things that other animals don't. Like, say, read blogs. But it can be tough to pin down what is fundamentally different about human intelligence. The cognitive basics, like memory and reasoning, are common in the animal kingdom; is there any one thing that sets us apart?

When I discussed this article with people who have taken the Creyos cognitive tasks, a lot of people disagreed with the article's conclusions. Let me know what you think in the comments below.
