The Mid-Size Coffee Cup

Options tend to get chosen more often when they are the compromise alternative in a choice set.

Imagine that it's already half past eight in the morning and you should have been on your way to the office. There is no time to prepare the usual coffee and have a croissant. You must hurry to the bus station. Luckily, the bus has no delay and you are now almost next to the office.

You get down and you have the distinct feeling that you can't really start the day without the fresh smell of a coffee. You head to the little close-by coffee shop that you have passed so many times, but have never entered. With an invigorated spirit you go inside. On the big board behind the counter there are just three types of coffee to go: small, medium and large. Which one will you choose?

Notice that you are not really familiar with the store and its products. Scientists say that the most popular size of coffee anywhere in the world is the medium size. And it doesn't matter how much coffee there is in that medium sized cup. "Small" is just not enough and "large" is simply too much.

To Think About
Based on this idea product assortments can be optimized to maximize profits. Increasing the number of options in an assortment can encourage demand for the middle choice.
