On the need for empirically grounded experimental practices and interdisciplinary discourse

This response reinforces the major themes of our target article. The impact of key methodological variables should not be taken for granted. Rather, experimental practices should be grounded in the empirical evidence. If no evidence is available, decisions on design and implementation should be subjected to systematic experimentation. In other words, we argue against empirically blind conventions and against methodological choices based on unreflected beliefs, habits or rituals. Our approach will neither inhibit methodological diversity nor constrain experimental creativity. More likely, it will promote both goals.
