System effects and the constitution

"Abstract: A system effect arises when the properties of an aggregate differ from the properties of its members, taken one by one. The failure to recognize system effects leads to fallacies of division and composition, in which the analyst mistakenly assumes that what is true of the aggregate must also be true of the members, or that what is true of the members must also be true of the aggregate. Examples are (1) the fallacious assumption that if the overall constitutional order is to be democratic, each of its component institutions must be democratic, taken one by one; (2) the fallacious assumption that if judges are politically biased, courts will issue politically biased rulings. In these cases and many others I will discuss, system effects are an indispensable analytic tool for legal theory. A systemic approach implies that the choices of legal actors are strategically interdependent: the best course of action for any given actor will depend upon what other actors do. Judges deciding how to interpret statutes and the constitution, for example, cannot simply assume, idealistically, that it would be best for them to adopt the approach that would be best for all if adopted by all
