In Press: Repeated Judgment Sampling: Boundaries

THIS ARTICLE was published in Judgment and Decision Making in 2011, while I was a PhD student at Universitat Pompeu Fabra in Barcelona. Here's the short abstract:

Previous research has shown that eliciting multiple estimates from the same person and averaging these can produce accuracy gains in judgment tasks. I experimentally investigate this finding’s boundary conditions. First, the experimental results show that the kind of question being asked has an effect on the size of accuracy gains. Second, when asked to provide final answer on the basis of their estimates, a majority of experimental participants did not consistently average their answers. These findings suggest that reaping the potential accuracy gains from repeated judgment sampling may frequently be difficult.
