Tom Tomorrow has an interesting take on this, excerpted:
"First you corner a large-- if possible a very large-- number of people who, while they’ve never formally studied the subject you’re going to ask them about and hence are unlikely to recall the correct answer, are nevertheless plugged into the culture to which the question relates.
Then you ask them, as it might be, to estimate how many people died in the great influenza epidemic which followed World War I, or how many loaves were condemned by EEC food inspectors as unfit for human consumption in 1970.
Curiously, when you consolidate their replies they tend to cluster around the actual figure as recorded in almanacs, yearbooks, and statistical returns.
It’s rather as though this paradox has proved true: that while NOBODY knows what’s going on around here, EVERYBODY knows what’s going on around here."
Kind of like, you put a counted number of beans in a big ass jar, and get a group of people to make guesses as to how many beans are in there. No one will be actually close, or no more often than you would expect more or less by chance, but if you take the aggregate, averaged number, you get a remarkably accurate assessment.
For my money, thats a damned interesting phenomenon. Damned interesting!
And if it might be applicable in preventing deaths, hell, give it a shot! Whataya got to lose, except an little money. Sure, its a bit ghoulish, hell, its a lot ghoulish. But this is the Pentagon, people there think about people getting killed all day, every day.
