This is the final installment of my three part series on The Wisdom of Crowds by James Surowiecki.
In the first part of the series, I explained that, according to Surowiecki, in order for a group to be "smart," that is, in order for groups to make accurate predictions and decisions, the group needs to be diverse, independent, and decentralized.
Diversity brings in new ideas, independence insures that those new ideas get expressed, and decentralization prevents the sort of small minded group think that can lead a herd over a cliff.
Now here's where it gets interesting: In the months leading up to the September 11, 2001 attacks on the World Trade Center and the Pentagon--the U.S. intelligence agencies were organized in exactly this manner--diverse, decentralized, and independent. As Surowiecki writes, the U.S. intelligence community was, "a collection of virtually autonomous, decentralized groups, all working toward the same broad goal--keeping the United States safe from attack--but in very different ways." (p. 67)
In fact, U.S. intelligence agencies had all of the necessary pieces of information to know that an attack was coming. The CIA monitored and took pictures of a 9/11 planning meeting of Al Qaeda operatives in Malaysia in January 2000. The CIA knew that two Al Qaeda operatives moved to San Diego in January 2000. In fact, the Presidential Daily Intelligence Briefing for August 6, 2001 was titled, "Bin Laden Determined to Attack Inside the U.S" and Bin Laden wanted to hijack a U.S. aircraft.
So if we had all of the relevant pieces of data to prevent the attacks on 9/11 then how did they happen anyway.
THERE WAS NO AGGREGATOR.
In order for diverse, independent, and decentralized groups to make smart decisions there has to be someone to aggregate the information. Think about the example of a crowd at the state fair guessing the number of jelly beans in a jar--the aggregator is the person who adds up all of the guesses and finds the average. In a stock market, the aggregator is the New York Stock Exchange which collects all of the buying and selling information and shows the price of the stock (which reflects the collective wisdom of the group). For sports betting, the aggregator is the bookmaker in the casino who sets the point spread for the game.
In every Presidency before George W. Bush, the aggregator was the President of the United States. Think about how John F. Kennedy handled the Cuban Missile Crisis. He gathered all of the different viewpoints from all of the different defense and intelligence agencies in one room, had them all make their best case (which reflected the collective wisdom of their group), and then came up with a plan that reflected the collective wisdom of the entire group.
With President Bush, there simply is NO ONE at the top who is sifting through all the information to figure out the collective wisdom of all of the intelligence agencies. As former Bush administration counter-terrorism adviser Richard Clarke indicated, the Bush administration simply wasn't interested in counter-terrorism. Despite the warning the the Presidential Daily Intelligence Briefing, the President continued his vacation in Crawford, Texas.
After 9/11, again there was no aggregator of the information to figure out who did it and how to prosecute them. Cheney had already made up his mind to invade Iraq. Bush had already made up his mind to invade Iraq. Never mind that 15 of the 19 hijackers were from Saudi Arabia. If you've already made up your mind, the evidence never gets examined, the collective wisdom of the group is never identified, and poor decisions are the result.
In this case, the failure to aggregate the collective wisdom of the U.S. intelligence agencies has led to 2,974 American deaths on 9/11 and 3,646 (and counting) soldiers' deaths in Iraq. For all his talk of being The Decider, Bush has never fulfilled his responsibility as The Aggregator.
Speaking of collective wisdom, a poll by the American Research Group shows that 45% percent of Americans support impeachment proceedings against President Bush and 54% support impeachment of Cheney.
Among independents, 50% favor starting impeachment proceedings against President Bush, to only 30% opposed. And 51% of independents are also for starting impeachment proceedings against Dick Cheney, to 29% opposed.
