Re: Too much data

Hi Ryan,

check out the work of Barry Schwartz on "the paradox of choice" (here's the Ted talk: http://www.ted.com/talks/barry_schwartz_on_the_paradox_of_choice.html). He shows the  inverse u-shaped effect  you talk about:  choice is paralyzed & people less happy with their choice after the number of options goes beyond 6-10. We recently published a study that showed the same effect in an HCI context, in particular when using search engines:
 
Oulasvirta, A., Hukkinen, J.,& Schwartz, B. (2009). When more is less: The paradox of choice in search engine use. Proceedings of SIGIR, ACM Press, New York.

Best regards,
Antti
