"Art vs Science - I issue a restraining order, Science is to stay 100 yards from Art at all times"

IMO there is no one midset that suits hacking. The mental attitudes are as wide and deep as the discipline itself. One moment you need to be an Artist, the next you need your 'Codemonkey Engineering' head on, and after spending a while as a Linguist, a Mathematician, or whatever else your specialisms bring to the mix you have to be a able to become an Ignoramus, a Consumer and Yahoo to utterly beat and stress test your application. That's a lot of brainwork for one day.
