πŸ’Ž On the power of words (especially obscure medical conditions)

Listerine was invented in the nineteenth century as powerful surgical antiseptic. It was later sold, in distilled form, as both a floor cleaner and a cure for gonorrhea. But it wasn’t a runaway success until the 1920s, when it was pitched as a solution for “chronic halitosis”β€” a then obscure medical term for bad breath. Listerine’s new ads featured forlorn young women and men, eager for marriage but turned off by their mate’s rotten breath. “Can I be happy with him in spite of that?” one maiden asked herself. Until that time, bad breath was not conventionally considered such a catastrophe, but Listerine changed that. As the advertising scholar James B. Twitchell writes, “Listerine did not make mouthwash as much as it made halitosis.” In just seven years, the company’s revenues rose from $115,000 to more than $8 million.”

πŸ’Ž On how admitting a weakness on a minor issue makes a brand’s other claims more believable (Listerine, L’Oreal, and Avis)

When asking ourselves about such a person’s trustworthiness, we should keep in mind a little tactic compliance practitioners often use to assure us of their sincerity: They will seem to argue to a degree against their own interest. Correctly done, this can be a subtly effective device for proving their honesty. Perhaps they will mention a small shortcoming in their position or product (“Oh, the disadvantages of Benson & Hedges”). Invariably, though, the drawback will be a secondary one that is easily overcome by a more significant advantages — “Listerine, the taste you hate three times a day”; “Avis: We’re number two, but we try harder”; “L’Oreal, a bit more expensive but worth it.” By establishing their basic truthfulness on minor issues, the compliance professionals who se this ploy can then be more believable when stressing the important aspects of their argument.

πŸ’Ž On medical conditions (invented by advertisers)

In addition to the dread of auto-intoxication, the American consumer faced a positive assault course of other newly minted or rediscovered maladies – pyorrhea, halitosis (popularized by Listerine beginning in 1921), athlete’s foot (a term invented by the makers of Absorbiner in 1928), dead cuticles, scabby toes, iron-poor blood, vitamin deficiency (vitamins had been coined in 1912, but the word didn’t enter the general American vocabulary until the 1920s when advertisers realized it sounded worryingly scientific), fallen stomach, tobacco breath, dandruff, and psoriasis, though Americans would have to wait until the next decade for the scientific identification of the gravest of personal disorders – body odour, a term invented in 1933 by the makers of Lifebuoy soap and so terrifying in its social consequences that it was soon abbreviated to a whispered BO.
