How to Give Good Advice (and When Not To)

A carpenter took on an apprentice who cut a mortise badly. Not dangerously, not unrecoverably: badly, in a way that would show in the finished piece. The carpenter watched him do it, said nothing, and went back to his own bench. The apprentice, telling this story years later, said he spent the entire afternoon in a state of low fury, waiting to be corrected and not being corrected, and that this was the most instructive afternoon of his training.

At five o clock the carpenter came over, looked at the joint, and said six words: want me to show you something? The apprentice said yes. That yes, the carpenter told him later, was the only reason the next ten minutes worked. Advice given to a person who has not asked is received as a verdict on them. The same advice given to a person who has just said yes is received as information about the wood.

There is a whole practical craft compressed into this. First: almost nobody wants advice, and almost everybody wants help, and these are different requests that use overlapping words. Help is participation — you take a side of the load. Advice is evaluation from a distance, and it carries an implicit claim about the relative competence of the two people in the room, which is why the most technically correct advice in the world will bounce if that claim is currently unwelcome.

Second: the timing rule is not be gentle, it is be late. The carpenter waited not to be kind but because a person in the middle of a mistake is fully occupied. Correction lands during the pause after, when the hands are still and the person has already begun, privately, to suspect. Everyone knows the feeling of being told something you were three seconds from realising yourself; it converts a discovery into a humiliation, and the person will remember the humiliation and not the joinery.

Third: the question form. Want me to show you something is doing a specific job — it hands over the decision. If the answer is no, and it sometimes is, then the person is not ready, and advice delivered into that no does not become more true by being insisted upon. It simply becomes something they have to defend against, and defending against advice is one of the most reliable ways to become committed to a mistake.

There is a final piece, which is knowing when not to. The carpenter had one exception and it was absolute: if the apprentice was about to hurt himself, he shouted, immediately, with no question form and no waiting. He said the reason the shouting worked, on the two occasions he used it, was that he had never shouted about anything else. A person who corrects everything has no way to signal that this one is different. Restraint is not merely a courtesy. It is what keeps your alarm audible.

So the shape of it is: mostly say nothing, offer help rather than judgement, wait for the still hands, ask before you show, accept a no, and keep one loud voice in reserve for the day the chisel is pointing the wrong way. It is a slower way to be useful to people. It is also, as far as anyone has been able to determine, the only way that works twice.
