Explanation:

All of marketing is a battle of perception, not products. More specifically, marketing is about positioning your product or service in a positive light in the minds of the customers you want to reach. Because consumers are bombarded with so many messages on a daily basis, they routinely sift through the "noise." Selective perception marketing says your customers actively block or modify messages that conflict with their values and attitudes.
This scenario should be familiar to the many of us. Let’s say you have just purchased a brand new iPhone. No sooner had you bought the phone, than you see brand new iPhones all over the place! Another classic example is that when women get pregnant; they suddenly start seeing pregnant women everywhere. After childbirth, they stop noticing pregnant women and start seeing babies everywhere. This is called selective perception.
