Karl Popper's methodology highlights our scientific ignorance: hence the need to institutionalize open‐mindedness through controlled experiments that may falsify our fallible theories about the world. In his endorsement of “piecemeal social engineering,” Popper assumes that the social‐democratic state and its citizens are capable of detecting social problems, and of assessing the results of policies aimed at solving them, through a process of experimentation analogous to that of natural science. But we are not only scientifically but politically ignorant: ignorant of the (...) facts that underpin political debate, which are brought to our attention by theories that, as Max Weber emphasized, can be tested only through counterfactual thought experiments. Public‐opinion and political‐psychology research suggest that human beings are far too unaware, illogical, and doctrinaire to conduct the rigorous theorizing that would be necessary to make piecemeal social engineering work. F.A. Hayek realized that the public could not engage, specifically, in piecemeal economic regulation but failed to draw the conclusion that this was due to a specific type of political ignorance: ignorance of economic theory.

Parties are back, and many are cheering. Party polarization has voters seeing stark differences between Democrats and Republicans and demonstrating more ideological constraint than previous generations. But these signs of a more “responsible” electorate are an illusion, because the public is no more knowledgeable than ever about the type of “information” it needs if it is to exercise effective control over the public‐policy outcomes it cares the most about. Indeed, polarization has produced a political environment where both voters and policy (...) makers may be less likely to learn about the potential consequences of their governing choices. The result is that holding elected politicians to account for policies treated as divisive ends in themselves has become easier—but that holding them accountable for policies intended as means to the achievement of consensual ends has become harder.

American democracy is not unconstrained or autonomous, but instead achieves what could be termed value representation. Rather than affording representation on policy issues, elections transmit priorities among competing normative ends, while elite politics address the more complex matching of ends and means within the value boundaries established by voters. This results in neither policy representation nor state autonomy, but instead in a specific and limited form of democratic representation.

The partisan and ideological polarization of American politics since the 1970s appears to have affected pubic opinion in striking ways. The American public has become increasingly partisan and ideological along liberal-conservative lines on a wide range of issues, including even foreign policy. This has raised questions about how rational the public is, in the broad sense of the public's responsiveness to objective conditions. Widespread partisan disagreements over what those conditions arei.e., disagreements about the factssuggest that large proportions of the public (...) may be perceiving the facts incorrectly. The facts in question are important enough that these partisan disagreements may translate into sub-optimal policy preferences and electoral decisions. (shrink)
