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.

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

People will make worse financial decisions for them if they're choosing from a lot of options than if they're choosing from a few options. If they have more options they're more likely to avoid stocks and put all their money in money market accounts, which doesn't even grow at the rate of inflation.

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.

We either put out 6 different flavors of jam or 24 different flavors of jam and we looked at 2 things. First, in what case were people more likely to buy a jar of jam?
