Thanks for the thoughtful post, ! I am a professional salesperson and would love to delve into this issue with you. There are different "levels" to sales and successful salespeople will tell you that the sales approach should always be tailored to your audience. In my world, the false dilemma tactic is quite amateur and when I do use it, do so rhetorically, in a comical way, to illicit candid feedback and insight from my audience. "Poisoned well" arguments must be carefully crafted and well-timed. If they are not, the salesperson will certainly make a bad impression and turn off prospects.
In the coming days I will begin a salesmanship series of some sort and I would welcome your feedback as to what aspects of selling you are most interested in. I'm torn between posting for salespeople or posting insights from a salesguy meant for buyers. Hmmm?
