Today's TED video is also one of the most popular of all time. It is about the negative aspects of choice.
TEDGlobal 2005: Barry Schwartz on the paradox of choice (TED link)
I am making today a double feature! I just watched a new TED video that is also about the negative aspects of choice, but from a slightly different perspective.
TEDGlobal 2010: Sheena Iyengar on the art of choosing (TED link)
(Sorry that the embedded video is too large. I had no "choice". FYI, the video length is 24:09. You can also watch this video from TED's site where it will not be cut off.)
I was reading some of the comments about the second video. One person had this to say:
Apple limits choice because they know too many choices confuse buyers and increase chance for buyers remorse - thus, they only offer a few products in each line that are clearly distinguishable. Other tech companies like LG, Samsung, and HP produce so much variety that they have almost no solidified brand reputation.
