'Scientism' proposes the methods of the hard sciences - mathematical modelling - as the preferred, or sole approach to studying any topic, no matter how inappropriately (particularly social science).
In psychology this leads to operationalism, in economics to the neoclassical synthesis, in sociology to structuralist accounts of society.
The methodology is ubiquitous in contemporary thinking: listen to any 'expert' on the radio, TV or in the press.
Friedrich A. Hayek in "The Counter-Revolution of Science" characterised Scientism thus (my emphasis):
"The persistent effort of modern Science has been to get down to "objective facts," to cease studying what men thought about nature or regarding the given concepts as true images of the real world, and, above all, to discard all theories which pretended to explain phenomena by imputing to them a directing mind like our own. Instead, its main task became to revise and reconstruct the concepts formed from ordinary experience on the basis of a systematic testing of the phenomena, so as to be better able to recognize the particular as an instance of a general rule. ...In summary, Scientism removes intentionality from the world. It theorises as if people were Newtonian billiard balls, as if populations were classical manifolds - described by (usually linear) differential equations.
"The social sciences in the narrower sense, i.e., those which used to be described as the moral sciences, are concerned with man's conscious or reflected action, actions where a person can be said to choose between various courses open to him, and here the situation is essentially different. The external stimulus which may be said to cause or occasion such actions can of course also be defined in purely physical terms. But if we tried to do so for the purposes of explaining human action, we would confine ourselves to less than we know about the situation."
It requires severe contortions of mind to wrench-away all the common-sense complexities of the real (agent-populated social) world and to rely exclusively upon some oversimplified, reified model which then predicts counter-intuitive (and false) results.
Truly one has to be extra-smart and very-well-educated to jump through these hoops for Newsnight and Radio 4! It helps to be confident, well-spoken and well-connected too, for some reason.
