If you live with pets, you probably wonder what they're thinking, and marvel to the things they appear to figure out with their brains. But how high is your confidence in knowing what they're thinking?

He brings in examples from his own extensive work, and that of other scientists, to demonstrate how often we underestimate the intelligence of animals. Frans de Waal visited in 2016, and we revisit the interview here.
