Comments on an article by Duschinsky et al. (see record 2019-26304-001) and on response by Fonagy et al. (see record 2019-36958-001). Jurist would like to emphasize that Duschinsky’s (2019) interview artfully blends a review of well-established aspects of mentalization theory (like the varieties of nonmentalizing), along with attention to unfolding aspects (like epistemic trust and vigilance). In Fonagy et al.’s (2019) commentary, one launches into even newer ground with speculation about “the p factor,†which can predict vulnerability to psychopathology, and which could lead to move away from conventional diagnostic categories.
