This appears contradictory to your claim that the study is not credible. Using the publicly available information, please demonstrate one error or misrepresentation in the lists above, or please withdraw your accusation that the study is not credible due to the people performing it. Secondly, if we assume that the study is not credible and all the information is publicly available, I would have expected an opposition group to do a counterstudy. Since the linked PDF came out early August, there has been plenty of time. What I've seen is mostly "they're evul terrists and we must detain them".
