Those who never retract their opinions love themselves more than they love the truth.

Refusing ever to admit being wrong is a way of protecting your image at the expense of accuracy. Everyone is mistaken sometimes, so someone who never changes their mind is not always right, just unwilling to be seen as wrong. Pride has quietly become more important than getting things right.

Think of a view you once held strongly and have since abandoned. If you cannot think of one, that is worth noticing. Next time you realise you were wrong about something, say so plainly, and notice how little it actually costs.
