Being willing to evaluate and re-evaluate ones ideas and positions

Did you know that Dick Morris was a Republican when he worked as a key advisor for Bill Clinton? He tells in this video how he was raised by a staunchly Democrat family on the west side of Manhattan. "I used to believe that the reason people got more conservative as they got older was because they wanted to conserve their money. Then I realized that was part of it, but also because they realized that the Democratic ideas didn't work! He admits that Reagan's policies of refusing to negotiate with the Soviet Union worked, and that Dick's ideas would not have worked in destroying the Soviet Union.
