Advertising agencies stress the distinction between message inputs and what people take out of communication. The message needn't be too literal. Take the audience on a journey and let them draw their own conclusions; don't beat them over the head with a blunt message.
The subtlety of good advertising and the art of priming an audience to be receptive to communication is perfectly captured in a scene from the film Inception.
If you haven't seen the film, stop here!
In Inception, a rational message needs to be delivered to the heir to a great business empire - that he should dissolve his father's business. But, this is a message he simply won't buy. Only through tapping into the emotional power of the bond between father and son, in a way that delivers a positive emotional outcome, will the message ever have a chance of success.
The way forward is to convince the heir that his ailing father didn't want his son to be like him, but rather find his own way in life. The young man could not be forced; he needed to come to the realisation himself.
