The Hidden Persuaders (David McKay, 1957)

Every claim below was made in this book, quoted word for word and numbered in the order the piece makes them, so you can read it there rather than take our word for it. The book prints chapter headings its extracted text does not preserve, so the claims below are in the book's order but not grouped. The sentence above each quote is our reading of the claim, not their wording. Each quote was checked against a stored copy of the page at build time; where the two differ, the quote is the fact.
