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 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?

We also don't always know what we want. And in those cases it can actually make us worse off because it's actually easier to figure out what you want and to figure out how the options differ if you have about a handful of them than if you have a hundred of them.

You get to decide how you're going to look and what you're going to be when you grow up and when people learned that my parents actually had an arranged marriage people thought that was the most horrific thing on earth. I mean how could anybody allow their marriage of all things to be prescribed by somebody else?

And guys will say looks matter, but they'll also say things like "Well, she should be smart and kind." And you know those are... so the typical responses and if you give them just a few options, like five or six, then they will rate them on the very characteristics that they said were really important to them.

Now if you expand their choice set. Say you give them 20 different speed dates, everything goes out the window. Everybody starts choosing in accordance with looks because that becomes the easiest criteria by which to weed out all the options and decide "So who am I going to say yes to?"

If you have the feeling of choice, if you feel free, you will be better off. And when I say better off I mean that if people feel they have control over their lives, they call in for fewer sick days from work. They have a lesser probability of having a heart attack or stroke. They live longer. They're happier.
