I've done a number of studies with speed dating and Match.com and what's interesting is that you know we still walk into a speed dating event, you know, thinking about what it is we're looking for in a mate and so you ask people, like women will say "I'm looking for somebody who is really kind and sincere and smart and funny."

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.

So on the one hand in school you're teachers are constantly telling you that you can be whatever it is you want to be as long as you put your mind and heart to it, and yet at the same time I was also getting the clear message of, well, what can you do really?

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?

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?"

When Japanese went to Hawaii they would go straight and buy the same thing that they would buy in Japan. They just got it cheaper, which they liked. And so they would still eat the red bean ice cream or the green tea ice cream, but they didn't really take advantage of the variety and it wasn't clear that they cared.

I mean it wasn't that they sat around thinking oh gosh I needed more choices in my grocery stores the way I had come to think about it as an American growing up.
