This result has a bearing on the randomassignment problem. It is not clear, however, that randomassignment would promote selfless values in physicians any more than a one-sided draft does in professional football. Of course, small group differences are always possible when randomassignment to groups is employed; thus, the minor differences reported here are not surprising. To ensure that an environmental effect is free from genetic influences it would be necessary to have randomassignment to environmental conditions. Randomassignment would ensure that all unmeasured confounding factors were equally distributed between comparison groups. Unlike moderators (which, by definition, are baseline measures), mediators occur after random assignment, exerting their effects during the period of active intervention. The unequal numbers receiving each drug must also be questioned, given the apparently randomassignment. Moreover, these devices take advantage of experimental control, the randomassignment of participants to various 'treatments'. It must also be wondered how randomassignment would necessarily improve care for underserved patients. Although randomassignment to adversity and trauma are not possible, randomassignment to intervention is. No studies that we are aware of have tracked changes in glucorticoids over time during the course of a randomassignment preventive intervention with adolescents. It would be possible to integrate randomassignment with neural and behavioral measures across several time points in a larger study. Nevertheless, without the benefit of randomassignment, we cannot be absolutely sure that the changes we observed were a result of treatment. Successful randomassignment greatly reduces the likelihood that other unknown factors unrelated to the intervention, can account for any later differences between the two groups. Following randomassignment, no differences were observed between the resulting groups in gender distribution, age, birth weight, or percentage of life spent. A mediator variable, on the other hand, occurs after randomassignment and has its effect during the intervention. Recall that the control and intervention groups were created by randomassignment of boys displaying high levels of disruptive behavior in kindergarten (age 6). I closed my original commentary by saying that a more searching argument will be necessary before we swap the existing match system for randomassignment. Even when randomization is possible, the initial success in randomassignment does not ensure that experimental and control groups will remain comparable throughout the study. Our unobtrusive measure of racial attitudes is based on the randomassignment of respondents to different treatment groups. These examples are from corpora and from sources on the web.
