You can, probabilistically. If you randomly sample cars from all the street-legal models in the US (for example), and sort them by how fast they are based on appearance only, you would not be 100% correct, but you'd probably do much better than if you claim that "You can't understand very much at all just based on how things look" and sort them randomly (the prior being that each car is equally likely to be anywhere in the distribution).
