Sadly, the conclusion reached by Green and Armstrong (2006) – that experts should not be used for predicting the decisions that people will make in conflicts – comes as no surprise. Decades ago, Armstrong himself taught us that expertise beyond a minimal level does not improve judgmental accuracy across a variety of domains (Armstrong, 1980). More recently, Tetlock (2006) drove home the point in a study of hundreds of political experts who made thousands of forecasts over many years. Like Green and Armstrong (2006), Tetlock (2006) found that that expert forecasts were frequently inaccurate. In a nod to Armstrong's previous work, Tetlock (2006) suggests that avid readers of the New York Times should be able to predict political events as well as highly trained experts.
