Edward Bernays figured this out long beforehand when cake mix companies in 50’s had trouble convincing women to buy their product- because housewives felt guilty for not baking something from scratch- so Bernays (Freud’s nephew, befittingly) suggested for the boxes to say “just add an egg”- and suddenly the product flew off the shelf, alleviating women’s guilt for it being *too* easy.」7月6日 21時29分
