Blue trees, green seas, and birds chirping. I’m lying there on the sand beach enjoying the warm sun and suddenly a familiar melody comes in the wind. Before I could realize the tune, I’d be sucked into reality only to realize that it was my alarm tone – (🎵🔈🔈💥🎵 I’vvvveee becommmme so numb!! I can feel you thereeee! Become so dumb…! 🎵🔈🎵). Waking up with the loss of orientation and loss of memory…

Just realized that I don't use the same shampoo two days in a row because someone made me believe that continually using the same shampoo is somehow bad for your hair. Now regardless of this being true or not, I believe(d) it and haven't washed my hair with the same product twice in a row since, meaning that I always need to have two bottles of shampoo at hand.

Using this manipulation of belief, what other perceptions can marketers alter to double sales, or even use? I know Axe once had a great campaign where they turned two Axe "flavors" into one new one by using them together, thus doubling sales AND consumption.

Surely this can, and probably has been, used for other products like: tooth paste (day and night products), deodorant (no one should smell the same every day), and other cosmetic products. We live in an age where consumers want variety in most choices they make (food, clothes, entertainment), why not shake-up the products you use in your daily routine?
