Randomized controlled trials : how can we know “what works”?

Cowen, N. and Virk, B. and Mascarenhan-Keyes, S. and Cartwright, N. (2017) 'Randomized controlled trials : how can we know “what works”?', Critical review., 29 (3). pp. 265-292.

Abstract

“Evidence-based” methods, which most prominently include randomized controlled trials, have gained increasing purchase as the “gold standard” for assessing the effect of public policies. But the enthusiasm for evidence-based research overlooks questions about the reliability and applicability of experimental findings to diverse real-world settings. Perhaps surprisingly, a qualitative study of British educators suggests that they are aware of these limitations and therefore take evidence-based findings with a much larger grain of salt than do policy makers. Their experience suggests that the real world is more heterogeneous than the world imagined by evidence-based policy enthusiasts.
