The Rowling Protocol, Steven Bannon, and Rogue POTUS Staff: a Study in Computational Authorship Attribution


  • Patrick Juola


A key step forward in the professionalization of forensic science is the 
development of standards of practice and protocols. Based on his analysis of the
Rowling case, Juola (2015) proposed a systematic protocol for authorship verifi-
cation. We present both a theoretical and an empirical analysis of the accuracy
of this protocol. We further present a demonstration of this analysis in terms of a
high-profile case of political activism. We show that this protocol produces accurate
and understandable analyses of the likelihood of common authorship.
