Marketing, marketing, marketing. Most people don't think beyond what the manufacturer tells them Beats are the best because Monster says so. Skullcandy is the best because the Skullcandy marketing department advertises they are. After all, they wouldn't lie, would they? Their target audience are sheep when it comes to buying stuff. Tell them it's the best and they believe it. There should be some kind of class in High School about "getting the most for your hard earned money".Believing advertising rolls over to a lot of things. Look at all the 4 wheel drive soccer Mom driven SUVs on the road. The only time 99.99% of those behemoths see "off the road" is when Mom cuts the corner backing out of the driveway and drives across the lawn. They don't need a 4 wheel drive SUV but Ford & Chevy said they did. (this is me stepping off my soap box).
I've said this on many occasions. I'd expand it to advertising and social psychology in general. Fact is, there are people who are going to try to sell you something. It could be a political or social viewpoint, a product, or something intangible like an image. They're not going to tell you that they're trying to manipulate you. It's up to you to recognize this and resist, if you figure it's something you don't want. Unfortunately most people are terrible at this sort of thing. I've been skeptical of advertising for a very long time, but that's because I was taught to be so. If advertisers/politicians/etc. are going to use what social psychology has taught us about human nature, then at least people should be taught how it works, too, so they can defend themselves. It's only fair.
