Arguments for Randomrizing

I have organized my remarks about randomizing under four hea.dings: computation, communication, causal. Inference, and complexity. It is hard to think of a Pore controversial subject than that of randomization. My remarks are simpler and more extreme than they ought to be. I have put them in a rather bald and definite way in order to draw the lines more sharply and to make my message as clear as possible. I do not doubt that under extended debate it would be necessary to qualify some of the things I have to say, but I would insist on the point that I would be offering qualifications, not retractions.
