The Ten Commandments of Experiments

Because political science draws heavily from other disciplines—psychology and economics—in its use of experimental methods, we often fail to note how each experimental tradition developed in ways, while serving those field's primary goals, that often present contradictory imperatives that may not serve political science equally well. I provide a brief history of experimental traditions in psychology and economics, and then suggest, in all humility, an integrated set of best practices for the use of experiments in political science.
