Abstract
Some aspects of democracy appear more sensitive than others to the availability throughout society of political information. Individual-level political engagement poses a puzzle in this regard. An instrumentalquantitative conception of information that is central to rational theories and is also found in some behavioral theories of participation appears contradicted by historical trends. I treat the contemporary expansion in political information made possible by new information technology as a form of natural experiment. I test for a relationship between information availability and political engagement using survey data about Internet use in the period 1996-99. This test is relevant to the applied debate over whether the information revolution will prove salutary for participation, and at the same time sheds light on contending theories of information. I find little relationship exists; the only form of participation which is demonstrably connected to Internet use is donating money This finding fails to support instrumental conceptions of information and instead endorses cognitive conceptions employed in psychological and certain behavioral theories of political engagement.
