''The best way to get the best out of an arugment, is to avoid one.''

Arguments, just make people resent you and go on the defensive, no matter what arguments you bring up, they will justify their own, to get them to back down and change their mind is pretty much impossible...even if you are right.

But if your really bent on it, IEIs are good at arguments if they learn to take in information objectively, intead of only taking in information to reinfroce/support their beliefs.
