## Resource

In this episode, we explore the enduring lessons of Arthur H. Dunn’s Scientific Selling and Advertising (1919): why truth, trust, preparation, product knowledge, and buyer education are foundations of ethical persuasion.Drawing on verified historical commentary and quotations, the hosts connect Dunn’s early sales philosophy to consultative selling, long-term customer relationships, and sustainable wealth creation.This episode is a historical analysis based on verified secondary sources and quotations; it is not a chapter-by-chapter summary of the complete book.Key ideas: “If the truth won’t sell it, don’t sell it.” Frankness and sincerity build confidence. A salesperson should educate the buyer, improve judgment, and save time. Preparation and deep product knowledge make persuasion more credible. Ethical selling creates trust and long-term value.
