The most important scientific mindset is being willing and able to prove yourself wrong. It's an important legal mindset, too, because it's an important mindset for any honest debater: You prepare an argument by attacking it, and trying your damndest to be the best argument for the opposition you can possibly be. That's important in moral issues, where there arguably is no "right answer" to certain questions, but it's vital when things come down to factual questions where one position is right, any other position is wrong, and being able to recognize when you're holding a position which is wrong is vital to being honest, not only with others but with yourself.
