The specs nobody read

A man in Dammam is selling his car. He writes the advert carefully: engine size, mileage, every service date, the brand of the tyres, the new battery, the tint. It runs to two screens. A handful of people call, ask the price, and are never heard from again.

On the same street, a neighbour sells a similar car in two days. His advert is three lines long.

The difference is not the car. A colleague of the buyer knew the neighbour and said he was straight. The neighbour answered the phone warmly and offered to meet at a garage of the buyer's choosing. Half the street had seen him wash that car every Friday for years.

We pile on detail because we think detail is what persuades. It rarely is. The only reason to explain anything, whether it is a car, a CV or a new idea, is to get another person to do something. And people do things for reasons that sit underneath the facts: an itch they want settled, a sense of how the choice will make them look, a wish to belong among those who have already made the same choice.

Every one of those depends on trust. Without it, no amount of detail makes the call happen. With it, the detail becomes a formality the buyer skims on the way to yes.

A long list is one way to earn trust. It says I have nothing to hide. But it is slow, and it asks the reader to do all the work.

There are other ways in. A name someone already believes. A voice that sounds like it would pick up again next month. A history that people have watched with their own eyes.

The first man did not explain too little. He explained in the one language the buyer was least likely to hear.
