Since to date there has not been an adequate review of the methodological transparency of journal articles that include interviews with extremists, this study analyzed the content of 48 articles that involved such interviews.
The number of journal articles that rely on data derived from interviews with extremists has increased substantially over the past decade. This burgeoning invites the possibility that standardized reporting practices have not been explicitly clarified. The current study found that field-wide methodological transparency is lacking. Recommendations are presented for improving methodological transparency, with the implication that consensus on optimal reporting practices within the extremism literature should be reached soon.
