An excerpt from my PhD thesis notes:
Particular outcomes identified for terrorist groups include: (i) the achievement of a particular strategic vision (Y1); (ii) asset expropriation for decision elite or leadership control (Y2); (iii) promulgation of a particular political or religious ideology (Y3); (iv) continuation through a successor group or institution (Y4); (v) evolving into a political party or developing a political wing (Y5); (vi) devolution into an earlier developmental phase or form (Y6); and (vii) negotiation of a peace deal with a nation-state’s government (Y7).
Process tracing can be used to identify these group aims from terrorist communiques and propaganda.
Sometimes you can causally or process trace an interest to a specific event that involved others. I have written in the past about how I encountered the legendary Anglo-French financier Sir James Goldsmith. This was likely a remanifestation of Goldsmith’s career arc in the 1980s merger wave. James B. Stewart reveals in his book Den of Thieves (New York: Touchstone, 1992) about the 1985 Predators Ball hosted by Drexel Burnham Lambert:
But those thoughts quickly vanished, for far more important matters were brewing that night in Bungalow 8. Boesky was in a corner talking quietly with Icahn; Sir James was in a group with Pickens and Flom. Murdoch and Lindner were chatting with Kay and Engel, the affable host. Within only a few weeks, Pickens would launch his bid for Unocal, Peltz would bid for National Can, Sir James would attack Crown Zellerbach, and Farley would go after Northwest Industries—all with Drexel financing. (p. 138).
Goldsmith’s Crown Zellerbach bid used greenmail and white knight practices (pp. 160-161). It led to renewed media interest in his work . . . which eventually led to my encounter with his work in 1995, and to revisit it in 2010.
