Sheena Iyengar 2: How to make choosing easier

TEDSalon NY2011
Sheena Iyengar: How to make choosing easier (script)
I love her story, especially her previous TED talk: The art of choosing. It is because she talks steady, precisely and strictly. However, this time, it's softer and easier
Summary
Although this survey was done by Americans, it won't have some differences about other countries. We have about 70 making decisions in a typical day. Making one decision has so many choices. It is said an overload.
And then, she introduces the ways that among so many choices, customers choose what you want to choose. The first is to cut. It means to get rid of the extraneous redundant opinions. Customers always freeze up in front of them. The second is to explian something concretely. You make them real more. The third is to be categorized. It'll be better to handle less choices, more categories. The last is to accustom condition for complexity. It leads from low choice to high chance. You must be sure that it's easier to choose. This is a small art of choosing.
