About 60% of the people stopped when we had 24 jams on display and then at the times when we had 6 different flavors of jam out on display only 40% of the people actually stopped, so more people were clearly attracted to the larger varieties of options, but then when it came down to buying, so the second thing we looked at is in what case were people more likely to buy a jar of jam. What we found was that of the people who stopped when there were 24 different flavors of jam out on display only 3% of them actually bought a jar of jam whereas of the people who stopped when there were 6 different flavors of jam 30% of them actually bought a jar of jam.

We began to look at "Why is that?" And a large part of that has to do with the fact that when people have a lot of options to choose from they don't know how to tell them apart. They don't know how to keep track of them.

If you truly have expertise - and expertise can be say a chess master who has really mastered something or an artist or a musician of some sort you know if you give a jazz musician.

Now to what...? How we teach people to make choices and the things they're going to make choices over - that is culturally learned.

Are you going to be able to shave your legs? Are you going to be able to get married? So it was constantly thinking about both choice in terms of possibilities - I mean because choice is the thing that is supposed to enable you to be whatever it is you want to be - and yet, at the same time you have to think about choice in terms of its limitations.

I didn't really give them anymore than one choice, soda or no soda. They didn't... whereas we put a lot of stock in the differences between soda.

They [people] start asking themselves "Well which one is the best? Which one would be good for me?" And all those questions are much easier to ask if you're choosing from six than when you're choosing from 24 and if you look at the marketplace today most often we have a lot more than 24 of things to choose from.
