People don't put as much of an emphasis in expanding their choices, so that, you know, one of the things that I learned when I was in Japan way back in the 1990's and there were all these quarrels happening between the U.S. and Japan about allowing more American products into the Japanese market.

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.

This is at a time when you know most of us drank tap water, so I used to go to this store and examine all the varieties and we used to marvel at all the choices out there, but I found that I rarely bought anything and I kind of thought that was kind of curious. I mean, they had things that the other grocery stores didn't have and yet I never bought anything.

Most of the time you should use reason, there is no doubt about that because gut often makes us susceptible to lots of different biases, particularly if what you're deciding is something that you really, that expertise can be brought to bear on it, there is a way in which you can align the odds, so then you should really use reason.

We do the same thing in our own lives, embracing information that supports what we already prefer or vindicates choices we previously made.After all, it feels better to justify our opinions rather than challenge them, to contemplate only the pros and relegate the cons to the back of our minds. However, if we want to make the most of choice, we have to be willing to make ourselves uncomfortable. The question is, if we are willing, how exactly do we go about fortifying ourselves against these biases?

One could even argue that we have a duty to create and pass on stories about choice because once a person knows such stories, they can't be taken away from him. He may lose his possessions, his home, his loved ones, but if he holds on to a story about choice, he retains the ability to practice choice.

Consumers presented with six choices on an item were twice as likely to buy as consumers overwhelmed with 24 varieties of the same item.
