The more choices you give people, the harder it is for them to choose, and the unhappier they’ll feel. See, for example, Barry Schwartz’s book, The Paradox of Choice. Let me quote from the Publishers Weekly review: “Schwartz, drawing extensively on his own work in the social sciences, shows that a bewildering array of choices floods our exhausted brains, ultimately restricting instead of freeing us. We normally assume in America that more options (‘easy fit’ or ‘relaxed fit’?) will make us happier, but Schwartz shows the opposite is true, arguing that having all these choices actually goes so far as to erode our psychological well-being.”
And in what I believe to be an amazing paradox itself, instead of linking to an Amazon link where you can buy the book, or maybe the book or author’s home page, instead he links to a site that provides 20 different purchase links. If that isn’t a paradox of choice paradox I don’t know what is.
Google provided a great example of how less choices is better then more choices. They were one of the first search engines to assume an AND between search terms instead of an OR. Other search engines would make your results larger the more words you added to your search, while Google would make it smaller, allowing you to drill into what you are looking for. Also Google’s user interface has always had very few links. Their home page still only has 13 links. I don’t even what to try counting the links on any other search engine or portal site.
