Fifty Shades of Terrorist Credit-Taking: A Review of the Existing Scholarship on Terrorist Credit-Taking.

The consistently low credit-taking rates, 16 percent in 2016 (Global Terrorism Database), continue to challenge the understanding of terrorism as "propaganda of the deed" twenty years after researchers initially pointed out the conundrum. While providing an overview and evaluation of the limited existing literature on credit-taking, this paper draws attention to three core problems in the current literature on terrorist credit-taking, which may have led the low credit-taking rates to appear more puzzling than is due. First, the available explanations struggle to find corroboration when empirically tested and many also show theoretical shortcomings with strong unspoken assumptions and unclear predictions of credit-taking behavior. Second, data structure and data availability unnecessarily narrow our academic understanding of credit-taking. Finally, theories focused on group characteristics such as religious motivation or state sponsorship suffer from severe issues of sample bias due to unintended selection on the dependent variable. The paper concludes with suggestions for future research less prone to the problematic issues identified in the article. A re-orientation toward a less restrictive and more fine-grained understanding of credit-taking is advised. [ABSTRACT FROM AUTHOR]
