February 2, 1971 Dr. Carl 0. Muehlhauge U.S. Department of Commerce National Bureau of Standerds Washington D.C. 20234 Dear Dr. Muehlhause Thank you for your letter of January 25th. I would indeed be interested in more details about the value distribution studies mentioned in your letter and in particular the work by Professor Lave on automotive safety, My intereat in the latter dates back to 1955 when I joined « group in the state of Wisconsin to implement obligatory seat belts (this was after a graduate student who. I hed predicted would have a brilliant cereer. was partially decerebrated in an accident in which several other occupants of the car were left unscratched). I would concur in the importance in developing value distributions but not without some crepitations about potential errors end abuses. These adverse possibilities are shared by most system studies that depend on neceasargly oversimplified models of the real world, and I em sure I need not dvell upon them, Let me stress, however, that the present “market" for safety is very far from rational as already illustrated by the dispersion of life values mentioned in your letter. The main purpose of such value distribution studies should be to point out glaring inconsistencies in our approaches to policy. For this purpose relative evaluations are elmost as useful as absolute ones; the latter are in grave danger of being abused, i.e., when conclusions drawn from safety analysis are uncritically assimilated into other aspects of ecenomic policy. On the other hand, we waste wich energy in social division and squander many resources by failing to recognize where cost-effectiveness lies in our pursuit of safety. (And, of course, one must say much of the same for health end for many other values. ) Se, I would be very mich in favor of extending social research along these lines, but I would also emphasize these cautions. When consumers are wore often then not quite unable to make rational choices we should net use their behavior es a justification for the existing price system, (You will recognize in this remark the thread of my criticism of Chauncy Stear's efforta. I would, in fact, be such interested if you know of the other critical studies of bis work, Sincereiy yours, Jeshua Lederberg Professor of Genetics over ert TAME Dr. Carl 0. Muehlhause =-2- 2/2/71 P.S. Somewhere in this study we have to include a place for the paradoxical value affirmatively placed en risk - you might say the death instinct that many people exhibit! I do not think one should necessarily equate the value of the thrill function with @ negative valuation on human life although this would be a logical consequence of a simple analysis. JL/rr
