Bon Appetit:

Think about your usual supermarket routine. Chances are, if your market is designed like the majority in the U.S., you start shopping at the right side of the store and work your way around the outer rim of the supermarket—with occasional forays into certain aisles, but generally sticking to a counterclockwise route till you get to the register.

Now you may wonder, Why do I always choose to go that way?

The answer is, you don’t.

These stories of how we are subtly (and sometimes, not subtly) manipulated in these situations are always fascinating to me. Similar psychology is going on in casinos, too.
