Being an educator is not only getting the truth right, but there's got to be an act of persuasion in there as well. Persuasion isn't always 'Here's the facts, you are either an idiot or you're not.' It's 'Here's the facts, and here is a sensitivity to your state of mind.' And it's the facts plus the sensitivity, when convolved together, creates impact. p. 262This combination of facts plus audience sensitivity is an excellent approach to take for every presentation.
