The increasing trend for applying randomized trials to alternative medicine is part of a larger social project to integrate orthodox and alternative medicinean aspiration of doubtful merit1and much hope has been pinned upon randomized trials to evaluate the effectiveness of alternative medicine.2 Thanks to the excessive zeal of the evidence-based medicine movement, it is commonly believed that randomization procedures confer automatic validity on an investigation, and consequently, that randomized trials will be able to generate objective evidence concerning therapeutic effectiveness.
This viewpoint misunderstands both science and randomized trials. Randomized trials may serve as a stepping-stone by which individual treatments from alternative medicine are incorporated into the science-based system by which orthodox medicine treats pathologies. But trials alone cannot establish the validity of systems of alternative medicine because their hypotheses lack the precision and formal complexity required to be testable and generalizable.1,3,4
Alternative/complementary/fringe medical systems are frequently discussed, but seldom
