Abstract. This paper presents new data and reviews the available evidence pointing to the existence of three main ingredients of militant extremist mindset (MEM). Three different methods of item development identified factors that we have labeled Nastiness, Grudge, and Excuse. In other words, there are in our midst nasty people who are more prepared than others to accept, approve, or even advocate the use of violence. When such people feel a grudge, in that they see somebody as threatening to themselves (or to members of the group they belong to) or think that the world is not a hospitable place in which to live, they may resort to violence. This violence is often accompanied by an excuse or justification that refers to a higher authority or a “noble” principle such as religiosity or utopianism. Although all three ingredients may be open to intervention, Grudge might be the most amenable. Social policies related to immigration and procedures for dealing with protest counterculture may be effective in reducing MEM. The most important, however, is the need to espouse principles of diversity and tolerance.
