Many scholars of contentious politics claim there is no such thing as a group that uses only one tactic, yet scholars, pundits, and the public routinely use single-minded terms like protestors, dissidents, and terrorists. Other scholars and research programs suggest that some groups are specialists who tend to stick to a single tactic to achieve their goals, such as non-violence, violence, or specific kinds of violence, like terror. We make the claim that both sides of the debate are empirically valid and that both types of group exist. That is, some groups tend to specialize in a single tactic while others use a variety of tactics. This paper examines the empirical distribution of group types by examining the mix of tactics that groups employ. The analysis helps resolve part of the debate and pushes scholarly thinking in new directions about how often, why, and when groups operate across this spectrum.

抗议者，恐怖分子或其他东西？如何考虑持不同政见者的群体

许多有争议的政治学者声称，没有一个团体只使用一种战术，但是学者，权威人士和公众通常只使用诸如抗议者，持不同政见者和恐怖分子之类的专一的术语。其他学者和研究计划表明，某些团体是专家，他们倾向于坚持一种战术来实现其目标，例如非暴力，暴力或诸如恐怖主义之类的特定暴力。我们声称，辩论的双方在经验上都是有效的，并且两种类型的团体都存在。也就是说，有些团体倾向于专门研究一种战术，而另一些团体则使用多种战术。本文通过考察群体采用的策略组合来考察群体类型的经验分布。
