Sometimes you find yourself "arguing" only to realize you're talking about the same thing using different words. In other words... you both agree.

In other cases you're arguing different aspects of the problem and not realizing it.

I do agree with you though, admitting being wrong is better than being stubborn and wasting time and progress. It is something everyone up and down the chain of command should take to heart, you'll find yourself wasting less company resources, time and energy.
