[The Dark Knight] How does Bruce Wayne do half of the things he does without giving away his secret identity?

Like I know he puts out the alibi about going on holiday with the dancers but none of them get asked about that and say “it was the weirdest thing. Less than a day in he dove off the boat and got into a plane and never came back.” And the pilot. He doesn’t question that he deals with Bruce Wayne AND batman?

There's a trope called refuge in audacity, a person doing something so over the top and strange that it takes attention away from other Details of a person's behavior.

I think loads of public figures and celebrities do this as either a way to bring attention to themselves or hide something about themselves to the public.

I think in the dark knight you see Alfred reminding Bruce to keep people aware of Bruce Wayne- mostly because it's one of the only things Alfred can do to keep from him being Batman 24/7. 

There's also that bit with Lucius Fox and that blackmailing accountant saying- who's going to believe a rich playboy is running around dressed as a bat.

People are more willing to accept a simpler explanation - Bruce is just a weird rich guy, certainly not a mentally troubled man that fights crime at night- not really needing to investigate him to explain his behavior any further.
