People see more clearly once they stop trying so hard to be right.

The effort to be right narrows what you can take in, since anything that does not serve the position gets filtered out. Once you stop needing to win, information you were previously screening out becomes available, and you frequently find the situation was more interesting than the argument.

Go into your next disagreement with the aim of understanding rather than prevailing. Ask more than you assert. You will end up better informed, and often more persuasive as a side effect.
