In this video, University of Essex Senior Lecturer Dr. Brian J. Phillips provides a virtual talk on “How Did 9/11 Affect Terrorism Research? A Look at Disciplines and Gender.” Terrorism research increased markedly after the attacks of Sept. 11, 2001. Beyond increasing, how has research on this subject changed in the past 20 years? I examine data on more than 6,000 academic articles on terrorism between 1970 and 2019, and the more than 1,600 authors of multiple articles. Several interesting findings emerge. (1) The post-9/11 proliferation of terrorism research does not appear to be winding down. (2) The proportion of terrorism research in terrorism and conflict journals decreased after 9/11, with other types of journals starting to publish a great deal of terrorism research. (3) Psychologists became the dominant subgroup of terrorism researchers after 9/11, displacing Political Scientists, although this trend appears to have now reversed. (4) The proportion of female scholars increased substantially after 9/11, outpacing the rise in academia generally. The seems to be at least in part because scholars new to the field after 9/11 were often from relatively gender-balanced disciplines such as psychology.
