I think I was always informally thinking about choice from when I was a very young child because I was born to Sikh immigrant parents, so I was constantly going back and forth between a Sikh household and an American outside world, so I was going back and forth between a very traditional Sikh home in which you had to follow the Five K's.

A clear right answer and the opportunity to change the options? This is the chooser’s dream.

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.

You know, or three kinds of ice cream bars and you'd see this and like this... okay they could clearly benefit from some more choices and I remember having these discussions with the Japanese because they you know they often like to go to Hawaii for vacation because it was definitely much cheaper for them and I would ask them, "So when you go to Hawaii, you know do eat all these other things?"

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.

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?"

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.
