The article analyzes some of the features of forecasting in social science using interdisciplinary approach. Main methodological problems of forecasting are considered. It is shown how interdisciplinary approach contributes to solving these problems. Not only benefits but also limitations of the interdisciplinary approach to forecasting are presented. The key idea of the article is that implementation of interdisciplinary forecasting projects is possible when full-fledged dialogue between the parties, based on a shared methodology, is organized. The paper summarizes some of discussions held in the All-Russian Scientific Conference “ Interdisciplinarity in the Modern Humanities and Social Sciences” (Southern Federal University, Rostov-on-Don, June, 2016).
