Game-playing may help intelligence
analysts1 with the serious business of identifying
biases3 that can cloud decision-making and problem-solving during life or death situations, according to researchers.
Analytic4 exercises conducted by researchers at Raytheon that used
scenario5-based games designed by Col. Jacob Graham, senior research associate in the College of Information Sciences and Technology, Penn State, showed that some of the participants displayed anchoring and
confirmation6 biases as they tried to determine responsibility and motivations for
insurgent7 attacks in the scenario. Confirmation
bias2 is the tendency to accept only information that supports current beliefs and attitudes, while anchoring leads people to overemphasize past
judgments8 or initial hypotheses in spite of new,
contradictory9 evidence.
"Biases are often difficult to identify, but it's important to recognize bias in decision theory and analysis," said Graham, who worked with Donald Kretz and B. J. Simpson, both
cognitive10 scientists at Raytheon Intelligence and Information Systems. "For decision
makers11, biases can make the difference in life and death decisions."
The researchers said that the idea to use games as a way to detect confirmation bias was rooted in recent studies that
implicated12 biases in number of national intelligence failures.
"There have been a lot of post-9/11 studies that looked at analytic tradecraft and intelligence failures," said Kretz. "What they found was that there are a number of significant obstacles to good and thorough intelligence analysis, but what gets mentioned over and over in these studies is cognitive bias."
Graham designed a series of games based on real-life situations that U.S. intelligence analysts faced in Iraq. He used information from a collection of digital documents and reports that he developed to create decision-making games for analysts.
"It's
fictional13, but it's very real," said Graham. "We are very careful not to give up secrets on how the U.S. operates."
The researchers, who report their findings at the IEEE Conference on Technologies for Homeland Security, today (Nov. 13), said the games used a chain of messages,
intercepted14 phone calls and intelligence reports that offered insights into the activities of
insurgent(叛乱的) groups in a poor area of Baghdad.
According to Kretz, three groups of nine participants, all engineers at Raytheon, were placed in the middle of an evolving scenario of a series of insurgent attacks. The subjects, who were college educated but not trained in intelligence analysis, had access evidence following each attack and were asked to assess responsibility and motivation after each attack occurred.
The first group
analyzed15 the data by trying to understand the relationships between known and unknown groups of people -- link analysis. Another group pulled information and weighed the importance of the data, called information extraction and weighting. Researchers briefed the final group on how to use competing hypothesis to explain reported insurgent acts. Creating alternative hypothesis is one way to avoid confirmation bias.
The team that trained in considering alternative hypotheses significantly outperformed the other teams when identifying the perpetrators and the intended targets, Kretz said.
