By testing the model of information cascades through the analysis of the recent political uprisings in Egypt and Syria, this study aims not only at enhancing our knowledge of the model and its possible application(s), but also hopes to specifically shed light on how concise its adoption by Shirky is with regard to social media. At the same time, it may contribute to our understanding of the recent political developments in the Middle East. It is important to mention at this point, that this paper does not aim at a general explanation of the occurrence of political protest in Egypt or Syria. While factors such as economic performance and resource distribution,8 rising (food) prices,9 demographic changes in combination with (the lack of) educational and economic opportunities,10 as well as sectarian divisions11 can be considered as possibly having contributed to the occurrence and development of political protest in Egypt and Syria respectively, they will not be discussed in detail here due to the scope and focus of this study. Within the broad framework of collective action theory, this paper solely focuses on how political protests might be regarded as information cascades (as understood by Lohmann) and the impact social media might have on these (as proposed by Shirky).
