I think marketing plays a huge role here. Being told again and again that you "need/want" it might act on your subconscious at one point. And people tend to trust the marketing and the big text on the label more than anything sometimes. The label says it's healthier, that promo on TV said cool young people consume it, etc. So you won't stop to "objectively" evaluate the product. Many blind tests for products turned over results that were completely the opposite of what the market was saying via sales numbers. Because without the label and the marketing driving the decision people had to fail back to good old fashioned taste (ex: this tastes better) and common sense (ex: this offers more for the same taste / price).
