That Word that you just Heard can Never Be Unheard.
A retired salesman I know used to say, “The quotes pattern is the easiest thing to use against really dirty competitors, and it’s a really good way to attack such slimy guys.” And he used to point in the direction of someone who opposes your sale, or use a negative anchor when he did it. I wouldn’t say a thing like that, though. It was the retired salesman.
You can use some friend or other salesman as a source of the quote, if you embed it in a presentation to customers, and then read it to them with just the right inflection, or anchoring the embedded part with a gesture or a facial expression. Read this paragraph again, until you understand it.
You can quote another customer against the people you want to attack.
You can use something a past customer used to say….. Something a mentor used to say….. Something your mother used to say……
As long as the tone of what you say insinuates that person is important or knowledgeable, the listener will be more likely to accept some of it as truth.
This is exactly why ‘old sayings’ are often held as true. You know what they always say, Those who don’t study history are doomed to repeat it.
If you just accepted that as true – ask yourself “Who the hell is George Santayana and why did you just give the presumption that he is correct?”
