Green and Shapiro's tour de force fails as a convincing critique of ra
tional choice applications in political science because it locks itsel
f into a statistical form of assessment. Rather than seeing the constr
uctive side of rational choice theory, both as an engine of theoretica
l development and as a source of non-obvious empirical insights about
politics, Green and Shapiro depart from the procedure in most sciences
, comparing rational choice against an ideal rather than some concrete
alternative. Finally, they fail to note the recent emphasis on sophis
ticated empirical testing of rational choice hypotheses.
