Face it – humans are pattern-seeking animals. We identify eyes, nose and mouth where there are none. Martian rock takes on a visage and the silhouette of Elvis appears in our burrito. Discover the roots of our face-tracking tendency – pareidolia – and why it sometimes leads us astray.

Plus, why some brains can’t recognize faces at all … how computer programs exhibit their own pareidolia … and why it’s so difficult to replicate human vision in a machine
