I'm wondering if there is a word to describe the action of continuing with a course of action, despite being aware of the inappropriateness of it, or with the certain knowledge that it will fail.
I'm not talking about simple stubbornness, and it's not arrogance. It's a simple matter of carrying on regardless.
I'll give an example:
Driving a car, entering a highway/freeway, despite knowing one does not have enough fuel to reach the next refuelling station. When this is pointed out, a simple reply of "We'll wait and see" is all that is offered.
