Varieties of criticism
Conservative criticism has nothing much to do with "left-wing" or "right-wing", because left-wing people are often very conservative, in the defined sense, while right-wing people can also be very radical, in the defined sense. The difference between "radical" and "conservative" has more to do with the belief in whether "a change to something genuinely new" is really possible and necessary. Radicals typically believe strongly that such change is highly desirable and necessary, and that it can be achieved. Their criticism is that there is "not enough" change. Conservative critics, by contrast, are very skeptical about any such change, because they feel the change is really "just another form" of something that already exists.
Right realism
Right realism, in criminology, also known as New Right Realism, Neo-Classicism, Neo-Positivism, or Neo-Conservatism, is the ideological polar opposite of left realism. It considers the phenomenon of crime from the perspective of political Conservatism and asserts that it takes a more realistic view of the causes of crime and deviance, and identifies the best mechanisms for its control. Unlike the other Schools of criminology, there is less emphasis on developing theories of causality in relation to crime and deviance (the tendency is to scientifically examine Official Statistics as evidence). The school employs a rationalist, direct and scientific approach to policy-making for the prevention and control of crime. Some politicians who ascribe to the perspective may address aspects of crime policy in ideological terms by referring to freedom, justice, and responsibility. For example, they may be asserting that individual freedom should only be limited by a duty not to use force against others. This, however, does not reflect the genuine quality in the theoretical and academic work and the real contribution made to the nature of criminal behaviour by criminologists of the school.
