Most of the stuff we do every day happens in patterns, like how we shop. You probably have never given it so much as a thought, but the chances are you enter the supermarket and then navigate the aisles in a counter-clockwise direction. It’s been designed that way. Data compiled in a study for my new book Brandwashed surveyed 200 stores revealing that shoppers who move counter clockwise spend $2 more per shopping trip than those who wheel their trolleys in the opposite direction. Human beings are naturally more inclined to move to the left (because it’s easier to reach out with our right arm to grab whatever it is we need), so a right-side entryway is a subtle yet effective means of ensuring a counter-clockwise shopping flow.

PS Keep your right hand in your pocket the next time you go shopping – it may save you $2!
