The LinkedIn FrumNetwork user that I recently corresponded with about the wisdom of the crowd brought up an interesting bit of conventional wisdom that she claims is at least partly apocryphal:
For instance, most people will probably "like" the answer "yes" to the question "Do you really have to shut the window if one person in the room is cold?" That's the "common wisdom", but it's simply not true. The correct answer is "sometimes yes, but sometimes not."
What's the story with this? When is such consideration mandatory?
