3. World's Greatest Detective? Blake's Better
As well as not being the inventor we thought he was, Nolan's Batman isn't the detective he should be either. In fact he actually cheats his way to a lot of his discoveries, and a lot of the time, Nolan's narrative requires so much mystery that Batman basically knows nothing for the most part until we do. He is a reactive superhero, rather than a detective on a hunt. He certainly isn't the world's greatest detective in the grand scheme of Nolan's universe, he comes in about fourth. Gordon surpasses him, and even Dent manages it, but the most damning evidence is the fact that Blake is vastly superior in detecting. After all, it is he who discovers Bruce Wayne's biggest secret from a look on Batman's face, which clearly indicates some superhuman intellect level, since it fundamentally breaks the rule that no character in ANY superhero world is allowed to acknowledge that the heroes look suspiciously like the infamous billionaire, or investigative journalist who are united in their obvious disdain for being inconspicuous.
