The Americans have a Latin term caveat emptor. It means “Let the buyer beware.” When persuading, presenting, convincing, selling Americans present the positive picture: what works. Americans do not feel obligated to present or to reveal what doesn’t work, what is negative. In the U.S. business culture the audience is obligated to expose what doesn’t work by asking critical questions. Persuasive is selling what works, and not what doesn’t work.
