Flip-Flopping

Todd Perdum analyzes good and bad flip-flopping (h/t the Dish):

But we’d all do well to remember the first political statement Abraham Lincoln ever made, on March 9, 1832, in his failed campaign for the Illinois legislature. Al Simpson keeps a copy on file in his BlackBerry, and he read it out over the phone: “Holding it a sound maxim that it is better to be only sometimes right than at all times wrong, so soon as I discover my opinions to be erroneous, I shall be ready to renounce them.”

Makes sense to me.  I've never understood why people value consistency over learning from mistakes.  Being consistently wrong isn't impressive to me.
