Both the social and engineering sciences search for appropriate aggregated outcomes -- a search that can be accompanied with complexities and ineciencies. As shown here, certain difficulties are direct consequences of adopted approaches; e.g., management style, choice of a division of labor, use of expertise and experts, or even the modeling of the physics. Particularly troubling is that even with reasons to believe that \success" has been achieved, this need not be true. These results are motivated by Sen's Theorem from decision theory. More general results motivated by Arrow's Theorem will be given elsewhere.
