[DC Comics] How many DC heroes are suspected of having double identities by the public? When Superman's cover was blown recently, a lot of people were shocked that he even bothered with being anything but Superman.

How well understood is it in the DC universe that many of the heroes maintain double identities like that? Is there any serious speculation about what Batman or the Flash do on their off hours, or is it assumed that they do hero stuff full time? If a hero with a more mundane day job got outed, would people find it odd that a superhero was living incognito like that or is that the general assumption that they do so?

This is confused by the fact that many heroes at DC *don't* maintain dual identities- Wonder Woman is very openly Diana Prince of Themiscyera, Arthur Curry is a hometown hero in the part of Maine he grew up in, and Atom IIRC openly lectures about his scientific experiences as a superhero.

Batman wears a mask, which implies he doesn't want you to know who he is, which implies he has a secret identity.  Wonder woman doesn't wear a mask, which implies she doesn't care if you know who she is, which implies she doesn't have a secret identity. Reasonable (and accurate) enough so far. If it looks like someone is hiding their identity, they presumably have a secret identity. Otherwise, they're probably a full time hero.  


Superman is weird because he doesn't wear a mask but he *does* have a secret identity. This is why people were confused. If someone is flying around the city with their face visible on national tv, you assume they have nothing to hide, and are probably very confused when you learn they A. do and B. succeeded at doing so for years.
