George Stigler défendit deux revendications importantes. 1) Ce que disent les gens à propos des choix n’a pas d’importance. 2) Toutes les institutions sociales sont efficientes à long terme. Je démontre que la seconde proposition découle d’une considération pour la rationalité économique à laquelle s’ajoute une préférence nulle pour le temps.Il est important de constater que la désapprobation d’une préférence positive pour le temps est un aspect de la moralité traditionnelle. Cela suggère que la seconde revendication de Stigler (...) est tributaire de la proposition selon laquelle ce que disent le gens à propos des choix est extrèmement important.George Stigler defended two important claims. 1) What people say about choice does not matter. 2) All social institutions are in the long run efficient. I demonstrate that the second proposition follows from considerations of economic rationality plus zero time discounting. It is important to note that disapproval of positive time preference is an aspect of traditional morality. Thus suggests that Stigler’s second claim depends upon the proposition that what people say about choice does matter very much. (shrink)

This survey report is a follow-up to the survey done by the Center for Business Ethics in 1984/85 which was published in the Journal for Business Ethics under the title of 'Are Corporations Institutionalizing Ethics?' (Volume 5, 1986, pp. 85-91). This 1989/90 survey was again sent to Fortune 1000 industrial and service companies to find out what they have done to build ethical values into their organizations. It reveals some interesting comparisons with the 1984/85 survey with regard to expanding efforts, (...) objectives, progress, and methods of implementation, along with some new information on their perception of public pressure for ethics programs and the need for ethics education. The survey shows where some progress in building ethics into corporations seems to be occurring and where much more work needs to be done. (shrink)

Statistical reasoning is an integral part of modern scientific practice. In The Seven Pillars of Statistical Wisdom Stephen Stigler presents seven core ideas, or pillars, of statistical thinking and the historical developments of each of these pillars, many of which were concurrent with developments in biology. Here we focus on Stigler’s fifth pillar, regression, and his discussion of how regression to the mean came to be thought of as a solution to a challenge for the theory of natural (...) selection. Stigler argues that the purely mathematical phenomenon of regression to the mean provides a resolution to a problem for Darwin’s evolutionary theory. Thus, he argues that the resolution to the problem for Darwin’s theory is purely mathematical, rather than causal. We show why this argument is problematic. (shrink)

The current assessment of behaviors in the inventories to diagnose autism spectrum disorders (ASD) focus on observation and discrete categorizations. Behaviors require movements, yet measurements of physical movements are seldom included. Their inclusion however, could provide an objective characterization of behavior to help unveil interactions between the peripheral and the central nervous systems. Such interactions are critical for the development and maintenance of spontaneous autonomy, self-regulation and voluntary control. At present, current approaches cannot deal with the heterogeneous, dynamic and stochastic (...) nature of development. Accordingly, they leave no avenues for real-time or longitudinal assessments of change in a coping system continuously adapting and developing compensatory mechanisms. We offer a new unifying statistical framework to reveal re-afferent kinesthetic features of the individual with ASD. The new methodology is based on the non-stationary stochastic patterns of minute fluctuations (micro-movements) inherent to our natural actions. Such patterns of behavioral variability provide re-entrant sensory feedback contributing to the autonomous regulation and coordination of the motor output. From an early age, this feedback supports centrally driven volitional control and fluid, flexible transitions between intentional and spontaneous behaviors. We show that in ASD there is a disruption in the maturation of this form of proprioception. Despite this disturbance, each individual has unique adaptive compensatory capabilities that we can unveil and exploit to evoke faster and more accurate decisions. Measuring the kinesthetic re-afference in tandem with stimuli variations we can detect changes in their micro-movements indicative of a more predictive and reliable kinesthetic percept. Our methods address the heterogeneity of ASD with a personalized approach grounded in the inherent sensory-motor abilities that the individual has already developed. (shrink)

In this issue of the journal “Lee Elder”,1 a pseudonymous dissident Jehovah's Witness , previously an Elder of that faith and still a JW, joins the indefatigable Dr Muramoto2–5 in arguing that even by their own religious beliefs based on biblical scriptures JWs are not required to refuse potentially life-saving blood transfusions. Just as the “official” JW hierarchy has accepted that biblical scriptures do not forbid the transfusion or injection of blood fractions so too JW theology logically can and should (...) permit the transfusion of whole blood when this is medically required.Few doctors would argue that they should override the adequately autonomous decisions of Jehovah's Witnesses to refuse blood transfusions even if they are likely to die as a result of such transfusions. However, there is a case to be made for doctors asking such patients to reflect on their potentially fatal refusal of blood and for drawing to these patients' attention the reasoning of members of their own faith that justifies acceptance of potentially life-saving blood transfusions. What is that case? Simply that doctors' primary professional duty to try to benefit the health of their patients entails trying to save their patients' lives when and if doing so will benefit their patients' health. Of course this is not an absolute duty overriding all other duties; in particular if patients who are adequately autonomous to do so refuse such life-prolonging treatment doctors must generally accept such refusal, however sadly. This editorial endorses that view in the case of adequately autonomous legally competent JWs. (In another paper in this issue of the journal Professor Shimon Glick argues that ethics committees should be empowered—as they now are in Israel—to override even competent refusals of life-prolonging treatment where the committee judges that ….
