What Do You Think of the Randomized Control Trial Method?

i followed with great interest your own critique of the randomized control trial method, of the r c t. And you wrote a piece on global development in sorrin world development, that actually summed up some of your concerns. I wanted to ask you here, for the benefit of the listeners, what you think of the rc t method,. Some say that that is the best way of coming up with unbiased and more consistent results. But others, like you, say that the main limitation to such experimental approaches is that they don't really address transformations, structural transformations, and the struggle for right.
