The fact that each nation came to believe in the virtue of whatever policy happened to be in effect when recovery began supports [the] argument that haphazard economic vacillations play an important role in determining which policy strategies become constructed as economically efficacious. This also tends to undermine the realist/utilitarian view, which suggests that policy improves over time as rational policymakers learn more about universal economic laws from experience, because wildly inconsistent policies won favor in different contexts.
