Since you mentioned Batman, I can obviously tell you never have read comic books just stereotype. Batman is not super strong. Batman can fight, but he is extremely smart. He invents most of his gadgets in the comics. He also does a lot of detective work in his comic books not just fighting. He is a member of the Justice League, but he came up with ideas on how to kill each member if they went bad. Tony stark creates his own armor and uses it to villains. The main problem with your article is you are talking about super heroes, not average people. If you want that I would suggest you read this new fancy thing called a book, super hero comics are made to make usually a teenager excited and what is easier to make a kid excited a dude beating up the bad guy or a policeman spending 40 pages investigating and arresting a purse snatcher?
Forgot to mention Hulk is really Bruce banner who has Super Intelligence just made a horrible mistake. Some other heroes that are extremely smart. Henry Pym, Reed Richards, Captain America, Peter Parker, Charles Xavier, Henry Macoy, and Michael Morbius(the marvel zombies is pretty great).
