A lot of advertising isn’t intended to influence people to make a specific choice, it’s to keep the brand in mind as an option in the first place. For example: if you’re going to buy soda from the store, you’re more likely to buy Coke or Pepsi than to buy RC Cola. Why? Because until I reminded you just now, you didn’t even remember that RC Cola existed.

“Comparing specs and functionality” is exhausting, technical, and almost as prone to pointless marketing gimmickry, like the megahertz wars. And it’s usually not worth the effort. Many purchasing decisions aren’t necessary to optimize, and many of the ones that are can only be optimized subjectively—which shoes fit the best to your feet, which helmets fit the best to your head, which furniture looks and fits best in your home. If you’re buying a motorcycle, the technical specs can be the best on the market, but if it doesn’t physically fit your body it’s a bad motorcycle for you.

So if you’re building a personality and a brand around your company and products, does that mean you’re expecting your customers to make irrational decisions? No, you’re just trying to get attention, get into people’s heads, and make them remember that you’re an option. And when it is a deciding factor, most of the time it’s because all of the other factors are meaningless anyway. If you buy Nike because you want to be like LeBron James, and you’re at least satisfied with the shoes and whatnot themselves, odds are that wearing a slightly better designed Under Armor shoe won’t actually make you happier anyway.
