RT Article T1 The Brain of Dexter Morgan: the Science of Psychopathy in Showtime’s Season 8 of Dexter JF American journal of criminal justice VO 44 IS 6 SP 962 OP 978 A1 Berryessa, Colleen A2 Goodspeed, Taylor LA English YR 2019 UL https://krimdok.uni-tuebingen.de/Record/1764201876 AB This article identifies and discusses on the ways in which biological influences to psychopathy are thematically portrayed in the eighth season of Dexter to describe Dexter’s psychopathy, particularly focusing on fatalism and the inevitability of succumbing to one’s “biological self.” This paper, utilizing traditional content analysis, focuses on seven qualitative themes surrounding “biological fatalism” and psychopathy in this final season of Dexter . As lay theories of psychopathy are thought to originate from the media’s conceptualization of the disorder, such thematic portrayals serve to potential affect lay understandings of psychopathy and correspondingly, how the disorder is treated and perceived in the criminal justice process as a modern psychopathy-related “CSI Effect.” The conclusion focuses on the messages that this final season of Dexter sends to the lay public about the biological influences to psychopathy and how this may create implications for the criminal justice system.
