Judges are human beings. Is their behavior therefore subject to the same effects that psychology and behavioral economics have documented for convenience samples, like university students? Does that fact that they decide on behalf of third parties moderate their behavior? In which ways does the...

Legal research is a repeat offender - in the best sense of the term - when it comes to making use of empirical and experimental methods borrowed from other disciplines. We anticipate that the field's response to developments in eye-tracking research will be no different. Our aim is to aid legal...
