This reminds me of the idea of net promoter score in customer satisfaction surveys. It's a variation on the idea that it's better to have imprecise knowledge that is relevant than precise knowledge that is irrelevant. Net Promoter Score replaces a litany of questions about satisfaction with a single question ('would you recommend this product to a friend' (yes/neutral/no -> 1/0/-1)? You take the average of this score ((yes - no) / total) and it corresponds roughly to the health of a product. The basic idea is that asking a bunch of questions doesn't really add much knowledge, and giving more choices and asking more questions can actually lead you down a false path.
