“…Autobiographical memory plays a critical role in the construction of individual identity, accounting for what occurs, and when in a lifespan. Given this, systematic analysis of terrorist autobiographies has the potential to offer understanding of psychogenesis, thought processes, reasoning, and social construction over a life course, an advantage not afforded in prevalence studies (Altier, Horgan, & Thoroughgood, 2012;Altier, et al, 2017;Altier, Leonard Boyle, & Horgan, 2020). Analysis of autobiographical data also limits participant reactivity via (a) removal of contamination effects found in observation studies (b) elimination of researcher-participant interactions, (c) removal of expectancy bias from participants, and (d) reduction of artificiality found in interview designs (Altier et al, 2012;Krippendorff, 2004).…”
