We become critical when we see arrogance. Consider the following explanation.
“Arrogant people ignore or downplay good ideas from others, as they cannot accept that others might have better ideas than themselves. This makes reasonable communication difficult and arguments impossible to resolve fairly as the arrogant person will not accept the other person’s point of view.” http://psychology.wikia.com/wiki/Arrogant
Michael Weed said, “Arrogance is ignorance in a suit.” One who is arrogant does not recognize it, indicating an ignorance beyond their own intelligence.
Leaders must guard against the appearance of arrogance. It is destructive to our influence and credibility.
