There are many reasons why people like to hear articulated that which they approve. It serves the ego: the individual has the satisfaction of knowing that other and more famous people share his conclusions. To hear what he believes is also a source of reassurance. The individual knows that he is supported in his thoughts—that he has not been left behind and alone. Further, to hear what one approves serves the evangelizing instinct. It means that others are also hearing and are thereby in process of being persuaded.
