Unwanted Consequences Quotes

“...it is one of the striking things about social life that nothing ever comes off exactly as intended. Things always turn out a little bit differently. We hardly ever produce in social life precisely the effect that we wish to produce, and we usually get things that we do not want into the bargain. Of course, we act with certain aims in mind; but apart from the question of these aims (which we may or may not really achieve) there are always certain unwanted consequences of our actions; and usually these unwanted consequences cannot be eliminated … We wish to foresee not only the direct consequences but also these unwanted indirect consequences. Why should we wish to foresee them? Either because of our scientific curiosity, or because we want to be prepared for them; we may wish, if possible, to meet them and prevent them from becoming too important. (This means, again, action, and with it the creation of further unwanted consequences.)
I think that the people who approach the social sciences with a ready-made conspiracy theory thereby deny themselves the possibility of ever understanding what the task of the social sciences is, for they assume that we can explain practically everything in society by asking who wanted it, whereas the real task of the social sciences is to explain those things which nobody wants -- such as, for example, a war, or a depression.”
