سیاست گذاری مبارزه با فساد مبتنی بر مدارک و شواهد (ارزیابی گزارش های سنجش فساد)

Outbreak of corruption could create a cycle in which corruption becomes highly prevalent in society. In this cycle, unscrupulous (or immoral) people are rewarded and honest people are weakened. As a result, the government's legitimacy in the eyes of the public would be at risk. Therefore, corruption must be investigated and evaluated, not only because of being a moral issue (that is), and not just the traumas that imposes on business and economics (which is also open), but because of the people (especially in developing countries) who are forced to burden any corruption charges. Assessment of international documents and reports on corruption is one of the fields of study on corruption which seems go be important. Albeit some of these reports have a global reputation but even they are not free of problems and defects and it can be said that they have some basic computational and methodological bias. this paper will try to articulate the main limitations of the reports which attempted to measure corruption and especially Transparency International "Corruption Perception Index” (as a document on anti-corruption policy) from the perspective of policy-based evidence. The issues of false perceptions and the misplaced use of these indicators will be discussed too. The method of collecting information is documental studies and the used instrument is notes taking.
