Now as a student in school I didn't exactly exceed in the subject of Science, and when ever I watch TV and see a product of certain interest there are several levels I factor in thinking, is this something I REALLY need?

There is a certain formula that goes into advertising consumer products, more than I was actually aware of. See for your self and if you have fallen victim to this "science" well... I have failed at the subject as well.

You step in the front door of your nearest chain grocery store. What's immediately to your right? At Wal-Mart, Kroger, Whole Foods and countless others, that's the fresh produce section. Some of them have their baked goods over there, too. And at those stores, the doors and registers are positioned to steer you that direction when you walk in.

This is because, after years of analysis of how humans move in a store, they've found that we're as easy to predict as animal migrations. Studies show that Americans like to shop counter-clockwise. Over time, they've found that stores that cater to this by putting the door on the right do better business than stores with the door in the center or, worst of all, the left.

Grocery stores are laid out to lead you around a set path you didn't even know you were following. Knowing you'll head right, they place the freshest, best-looking stuff they've got right in your path. Not the most popular stuff, mind you -- they know most of you didn't run to the store at midnight to buy lettuce, and they know that if they put the Doritos to the right, you'd grab them and head to the counter. Instead, they lead off with the produce, which tends to make the best psychological impression on you. The idea is that you'll associate the rest of the store with the freshness, bright colors and nice smells you got from the nicely laid-out produce.
