communication- insight?

A communication used to share an idea, concept, feeling is one thing. Communication used to manipulate is another. Actually to me all communication seems to be of the second type but not everbody admits to it.
And therefore not employing the device that truely seems to work for the second type seems to be the biggest reason any type of communication fails. A student of mass communication or comm.sciences would probably better explain it, but my take on the device that works best for the manipulative communication bit- Incomplete messaging works beter than complete messages. Let me explain.
Driving down a main road, you see a Levis Signature hoarding. The latest one thats in your town about the new cheap jeans from levis. The line says "At Rs. 599/- it doesn't hurt that much". What the visual shows however are what really hurts during those years of madness: the rotten-tomatoes-at-your-first-performance or cactus-on-your-backside-as-you-make-your-move situations we've all been through.
What has happened, is a casual line that directly states the marketing promise(cheap jeans) in borrowed lingo of the college youth, with a visual that says what has been left out. So the complete line should say: "At Rs. 599/- it doesn't hurt that much, but what really hurts are the rotten-tomatoes-at-your-first-performance or cactus-on-your-backside-as-you-make-your-move". Which if you've ever sat through a creative brief in an ad agency would be what would've been put in the "desired response" slot, as "research" showed youth saying it hurts because they can't afford a Levi's. Whew.
So, children, thats all you do- take desired response, break it in two, put the first half as line, suitably contextualised, put second half as background leaving your audience guessing how the bloody hell does it connect and when they get it... a 3D experience in a static medium. Kidding.

My real focus was on the last part...leaving your audience guessing with an incomplete message that they solve inside their head, feel suitably rewarded and boom... they like it. Happens all the time. Watch out when the best jokes are cracked or when somebody pulls that deadly comeback.
