		<description>[...] Prediction Markets vs. Decision Markets  James Surowiecki (who has just posted an interesting comment on Midas Oracle, at the bottom of the Ken Kittlitz interview) pointed to his 2003 New Yorker piece: Why do decision markets work so well? They are extremely efficient at aggregating information and tapping into the collective wisdom of a group of traders, and groups are almost always smarter than the smartest people in them. As in financial markets, the incentive to get the better of others (whether the reward is profit or mere satisfaction) causes traders to seek out good information. The absence of hierarchy—markets don’t have vice-presidents—insures that no single person has too much influence and that diverse viewpoints don’t get shut out. [...]</description>

		<description>"any inherent flaw in the concept":

- Just a remark, if I may. In my view, Robin Hanson (who was the guy in charge of the targeted area) made the mistake to focus on the Mid-East, an area of the world which the American traders have not the first clue about.
- I wonder what kind of information aggregation PAM would have gotten. Probably not much. A more secure choice would have been to target North America, but, as you know, there hasn't been terrorist attacks within the U.S. since 9/11 ---so there weren't much to divine (we know that now).
- The fact that PAM was killed before its grand opening propelled this DARPA program into stardom (and Robin Hanson into martyrdom), but, just like with any other human projects, the first versions always reveal problems ---that would have been the case for PAM, too.

The takeaway of the DARPA PAM program has been Robin Hanson's Market Scoring Rules, which is a design many people tell me great things about. I'm in despair to see Robin Hanson spamming any PM conference he is invited in with his concept of decision markets (a market-generated automatism that nobody needs and, thus, nobody gives the first fig about) instead of educating the crowds about MSR.

There is great need to talk about MSR ---both in a didactic way (for triple morons like me) and in a technical way (for PM-interested software architects and exchange managers).</description>

		<description>Just my personal case:

- I was intrigued about prediction markets by some MSNBC.com coverage on PAM ---end of July 2003, thus. I heard of the book, "The Wisdom Of The Crowds", well after. (((I'm not implying that I'm the incarnation of the "tipping point".)))

Jason Ruspini, when and how did you come into prediction market land?

Same question for the others, if they wish to take this non-scientific poll.</description>

		<description>Just to clarify: by the time the PAM story broke, almost all of The Wisdom of Crowds was written (I think I handed in the first draft in September or October 2003), and I had signed the contract for the book a couple of years before that. So the one didn't lead to the other.

One interesting sidenote to the whole PAM discussion is that I actually wrote &lt;a title="DECISIONS, DECISIONS" href="http://www.newyorker.com/talk/content/articles/030324ta_talk_surowiecki?030324ta_talk_surowiecki"&gt;a column for The New Yorker in March of 2003 that talked about DARPA's plans to use what I then called "decision markets" to improve intelligence forecasting&lt;/a&gt;, and the reaction to the idea both in-house and from readers was quite positive. That's always made me think that what killed PAM was really the way it was spun by Wyden and Dorgan -- and by the newspapers the next day -- rather than any inherent flaw in the concept. (Although, to be fair, my column focused more on the idea of using prediction markets internally than on opening them to the public at large.)</description>
