This paper presents comments on F. M. Moghaddam's article, (see record 2005-01817-002) which uses the metaphor of a narrowing staircase "to provide a more in-depth understanding of terrorism", describes the journey as being provoked by how people perceive of levels of fairness and experience feelings of relative deprivation. If the masses perceive injustice and feel deprived and cannot adequately influence the procedures through which such perceptions can improve, some are likely to begin climbing the staircase that eventually leads to enrollment in terrorist groups. The author points out two factors that also encourage such perceptions receive minimal attention in Moghaddam's article: Historical Conflict and Current Organized Incitement.
