Although congressional scholars agree that hearings are an important activi
ty, there is little consensus on their role in the legislative process. The
traditional literature on hearings plays down their role as mechanisms of
disseminating information because committee members often do not appear per
suaded by the information they reveal. We explore the premise that hearings
may not be informative to committees but may provide crucial information t
o the floor. If hearings have some intrinsic informative content and are co
stly, even extreme committees can transmit useful information to the floor.
The possibility of holding hearings creates an incentive for extreme commi
ttees to specialize and reveal information simply by the decision whether t
o hold hearings.
