Hi, Kuresu.
I think most creationists could be described as idealists who think their idealism is realistic.
Ideally, we
would do as Ten:Ten says and
prove our theories to perfection. Since this is the ideal, Ten:Ten and his ilk feel that this is what should be done, not even considering the possibility that the ideal is unattainable.
And, confirmation bias turns practicality of some theories into idealistic "proof," while parallel lines of evidence are not enough for other, unfavored theories.
