Do we have too many *ideas* to choose from?

Mark Steckbeck (his blog is very good) writes:

Barry Schwartz believes that Americans suffer from too many choices. (PDF file) The result is that we become overwhelmed with too many choices, become depressed, and consequently lead less fulfilling.

I’m certain that Schwartz did not mean that there are too many ideas from which to choose to believe in, but why not? It’s overwhelming listening to political ads during campaigns or editorials and stories on major topics in newspapers. As Ronald Coase said, the reasons for regulating markets for goods is no different than the reasons for regulating markets for ideas, execpt that there’s probably more reason to regulate the latter.

I wonder which ideas Schwartz recommends we eliminate from the set from which we choose.
