This paper deliberates on how the
results from assessments of social impacts should be applied for analyzing
studies. On the other words, The question is that how a researcher should
comprehend different but related impacts in a systematic way. And which
methodological paradigm should be chose on this systematic framework in
designing social researches? Inspired by Pawson and tilly (1997), the article
tries to add critical realism implications to the research design of social
impact assessment studies. The critical realism paradigm by emphasizing on the
organic links between different levels of reality and the way in which causal
consequences appear, could be a useful theoretical and methodological framework
for guiding social impact assessment studies.
