So I one day decided to pay a visit to the manager, and I asked the manager, "Is this model of offering people all this choice really working?" And he pointed to the busloads of tourists that would show up everyday, with cameras ready usually. We decided to do a little experiment, and we picked jam for our experiment. Here's their jam aisle. They had 348 different kinds of jam. We set up a little tasting booth right near the entrance of the store. We there put out six different flavors of jam or 24 different flavors of jam, and we looked at two things: First, in which case were people more likely to stop, sample some jam? More people stopped when there were 24, about 60 percent, than when there were six, about 40 percent. The next thing we looked at is in which case were people more likely to buy a jar of jam. Now we see the opposite effect. Of the people who stopped when there were 24, only three percent of them actually bought a jar of jam. Of the people who stopped when there were six, well now we saw that 30 percent of them actually bought a jar of jam. Now if you do the math, people were at least six times more likely to buy a jar of jam if they encountered six than if they encountered 24.
Now choosing not to buy a jar of jam is probably good for us -- at least it's good for our waistlines -- but it turns out that this choice overload problem
