註釋Evaluators with expertise in a particular field may have an informational advantage in separating good projects from bad. At the same time, they may also have personal preferences that impact their objectivity. This paper develops a framework for separately identifying the effects of expertise and bias on decision making and applies it in the context of peer review at the US National Institutes of Health (NIH). I find evidence that evaluators are biased in favor of projects in their own area, but that they also have better information about the quality of those projects. On net, the benefits of expertise tend to dominate the costs of bias. As a result, policies designed to limit reviewer biases may also reduce the quality of funding decisions.
