Jacqueline Stevens: Political Scientists Are Lousy Forecasters

DESPERATE “Action Alerts” land in my in-box. They’re from the American Political Science Association and colleagues, many of whom fear grave “threats” to our discipline. As a defense, they’ve supplied “talking points” we can use to tell Congressional representatives that political science is a “critical part of our national science agenda.”

Political scientists are defensive these days because in May the House passed an amendment to a bill eliminating National Science Foundation grants for political scientists. Soon the Senate may vote on similar legislation. Colleagues, especially those who have received N.S.F. grants, will loathe me for saying this, but just this once I’m sympathetic with the anti-intellectual Republicans behind this amendment. Why? The bill incited a national conversation about a subject that has troubled me for decades: the government — disproportionately — supports research that is amenable to statistical analyses and models even though everyone knows the clean equations mask messy realities that contrived data sets and assumptions don’t, and can’t, capture.

It’s an open secret in my discipline: in terms of accurate political predictions (the field’s benchmark for what counts as science), my colleagues have failed spectacularly and wasted colossal amounts of time and money.
