Does public ignorance matter?

Recent scholarship has attempted to restore the reputation of the American electorate, even though its level of political interest and information has not measurably increased. Scott Althaus's Collective Preferences in Democratic Politics challenges this revisionist optimism, arguing that opinion polls misrepresent the interests of a large segment of society, and that they therefore get too much attention as a guide to policy makers, because those being polled are so ill informed. But Althaus overestimates the degree to which respondent ignorance is responsible for the instability of survey responses; and he is perhaps too critical of polling as the vehicle for transmitting voter interests. His analysis of information effects on political attitudes, however, raises the important question of how public opinion would be different if it were well informed. The answer is, I believe: only minimally different.
