Yes, thank you. It seemed bizarre to me as I was reading the article that this point is not brought up at all. Of course, it’s impossible to perform controlled realistic experiments to disentangle the effects. But to not even acknowledge this crucial limitation in the research makes the reporting and research deeply flawed. The research would really need to take into account each conflict’s preconditions, which is a very daunting task, to become more reliable. I understand it’s hard to do this research, but it’s only fair to demand that researchers temper their conclusions based on to the limitations. That kind of rigorous approach doesn’t sell as many books or lead to as many media appearances though, sadly.
