Almost none of the discussion here accounts for time and growth. Almost all of us have had that moment where someone "argued" with us over something we were wrong about and unwilling to change at the time. Then later we have that aha! moment where we've let the ego go, changed, or simply realized the poor outcome they were trying to warn us of. Being right doesn't mean right now. Checking your ego means stating your cade, making the truth, or rightness visible, and then moving on to allow that person to find their way back to what you e given them. And, as many have pointed out if the ego is checked then you're also already primed to be wrong, and learn something yourself. Even if it means later when you've had time to digest it.
