I respect logic, and I respect a chance to mull it over. I'll admit, it's my initial impulse to shoot down any attempt to change my view, but if I have time to realize it's not the end of the world to consider other's views, it fares better. And when I mean time, I don't mean hours. It can be as little as 1 minute.
This is not to say that being steadfast and rooted in an opinion isn't helpful. I spend a lot of time defending our approach to life- when it has it's place in life. Just like an ENFP's impulse to be open and consider other ideas- not that it's wrong, but certainly can be out of place when there is a need to hold your ground, and it needs to be checked.
