Richard Coyne: ‘Everything is Code’.

As any student of semiotics knows, speaking in code is what we do — when we communicate. It’s normal. To speak directly is the exception rather than the rule. In the kind of work I’m involved in getting others to do what you think you want them to do is primarily an exercise in subtle influence, persuasion and suggestion, perhaps delivered as a “nudge” rather than an order. It’s the same in advertising. Only crude advertisers direct you to buy Weetabix — obviously, overtly, as a command.
