You don’t owe your old opinions any loyalty. They didn’t know what you know now.

Consistency gets mistaken for integrity. An opinion you formed three years ago was built from whatever information you had then, and holding it now is loyalty to an older, less informed version of yourself rather than to the truth. Changing it is not weakness. Refusing to is vanity with better manners.

Pick one view you hold mainly because you have held it a while, and go and read the strongest argument against it. Be willing to say your position has moved. People respect that more than they let on.
