Of all the things we are wrong about, error might well top the list ... We are wrong about what it means to be wrong. Far from being a sign of intellectual inferiority, the capacity to err is crucial to human cognition. Far from being a moral flaw, it is inextricable from some of our most humane and honourable qualities: empathy, optimism, imagination, conviction, and courage. And far from being a mark of indifference or intolerance, wrongness is a vital part of how we learn and change. Thanks to error, we can revise our understanding of ourselves and amend our ideas about the world.

A whole lot of us go through life assuming that we are basically right, basically all the time, about basically everything: about our political and intellectual convictions, our religious and moral beliefs, our assessments of other people, our memories, our grasp of facts. As absurd as it sounds when we stop to think about it, our steady state seems to be one of unconsciously assuming that we are very close to omniscient.

Take away the ability of an intelligent, principled, hard-working mind to get it wrong, and you take away the whole thing.

Parading our own brilliance and exulting in other people's errors is not very nice. For that matter, even wanting to parade our own brilliance and exult in other people's errors is not very nice, although it is certainly very human.

I can usually find my own way out of whatever dicey literary or linguistic situations I wander into, but I have to work much harder at the science.

Thirty-three percent of all of our regrets pertain to decisions we made about education.

If it is sweet to be right, then - let's not deny it - it is downright savory to point out that someone else is wrong.
