The customer's mind is the battlefield
The book was written by two American advertising executives in the late 1970s, a time when the average person was already bombarded by thousands of ads a day, long before the internet or cell phones. Their central idea unsettled the industry: winning isn't about improving the product, it's about winning space in the mind of the buyer.
The book named this scenario the overcommunicated society: the human mind receives too much stimulus to store it all, so it filters almost everything and only keeps what already makes sense with what's already inside. That's why you can scroll your Instagram feed for minutes on end, and when it's time to remember, only two or three brands are left.
The job of anyone selling is not to shout louder with more ads or more text explaining the product. It's to understand which drawer the customer's mind has already decided to put you in, before you even open your mouth, and to slip right into it instead of fighting it.
