along the consumer decision journey popularized by McKinsey, I think there are a number of opportunities to take advantage of both integral and incidental emotion - as consumers consider their options they may experience a range of feelings from being overwhelmed or uninformed during the awareness and consideration phases, to feelings of pride and regret post purchase, or they may just be transferring emotions from one situation to another. Smart businesses will protect against incidental emotion by building in transition moments, or transformative emotional experiences into their brand strategy and will take advantage of integral emotion by recognizing the emotions consumers experience when they decide to make a purchase.
