When No Communication is Best: Speed Skating, Morphine Overdoses and the Wings Fall Off Button
Very often I advise people how to communicate their messages more effectively, but there are some cases where the best idea is not to communicate anything at all but to design a product, process or system so that the message is not necessary. Intuitive user interfaces, for example, mean that you don’t need a user’s manual, and safety interlocks eliminate the need for warnings. Occasionally, though, people go to the other extreme and design their solution so that without very robust communication some errors are very likely.

We laugh because no airplane designer would even have a “wings fall off” button and it certainly wouldn’t be next to the recline button*.
