Ernest Dichter: The Soul of Brands + Why We Buy

In the case of soap, he found that bathing was a ritual that afforded rare moments of personal indulgence, particularly before a romantic date (“You never can tell,” explained one woman). He discerned an erotic element to bathing, observing that “one of the few occasions when the puritanical American [is] allowed to caress himself or herself [is] while applying soap.” As for why customers picked a particular brand, Dichter concluded that it wasn’t exactly the smell or price or look or feel of the soap, but all that and something else besides—that is, the gestalt or “personality” of the soap.

This was a big idea. Dichter understood that every product has an image, even a “soul”, and is bought not merely for the purpose it serves but for the values it seems to embody. Our possessions are extensions of our own personalities, which serve as a “kind of mirror which reflects our own image”.
