OCD and Coconuts
How my brain turned a tropical snack into an existential threat My mind sometimes has trouble shutting down. So naturally, one afternoon, it latched onto coconuts. This happened in the Caribbean, where coconuts are everywhere, lounging under palm trees like they pay rent. Back home in Montreal, my usual habitat, coconuts are exotic celebrities you meet only in grocery aisles, wearing price stickers and an air of mystery. But here? They fall from the sky. Casually. Like it’s no big deal. [...]
Revisiting “Ten Commandments for the Scrupulous” through the Lens of Inference-Based Cognitive Behavioral Therapy
This post republishes a previously published article, “Revisiting Ten Commandments for the Scrupulous through the Lens of Inference-Based Cognitive Behavioral Therapy (I-CBT),” co-authored by Frederick Aardema, Ph.D., Constance Salhany, Ph.D., and Fr. Thomas M. Santa, C.Ss.R. Fr. Santa’s Ten Commandments for the Scrupulous has long offered practical pastoral guidance for people tormented by scrupulosity. In this updated commentary, we revisit those principles through an I-CBT lens, showing how obsessional doubt is constructed by reasoning and imagination, not by genuine moral evidence [...]
Dead Dodos and Better Outcomes: Why Different People Need Different Treatments
For decades, exposure and response prevention (ERP) has been described as the “gold standard” for OCD. Yet the field of psychotherapy has a long history of declaring winners too early. Budd and Hughes (2009) reminded the field that psychotherapy research faces an inherent difficulty: treatments are rarely isolated enough to determine whether one approach is universally superior. This problem became central to what is known as the Dodo Bird Verdict, a reference to the dodo character in Alice in Wonderland [...]
The Myth of Inner Parts in OCD
IFS’s Growing Popularity and Why It Falls Short for OCD Internal Family Systems (IFS) has swept through psychotherapy over the past decade. Its language of protectors, exiles, firefighters, and inner families gives people a cast of internal characters to identify with. It is imaginative. It is intuitive. It gives emotional life a narrative shape. And for many conditions, that narrative structure feels meaningful or even comforting. Because of this broad appeal, IFS is now being pulled into the treatment of OCD. [...]
The Magic of ICBT: Seeing Through OCD’s Illusion
Illusion has always offered one of the clearest metaphors for understanding obsessional doubt. Not the trivial kind, rabbits in hats or cards up sleeves, but the deeper magic of psychological illusion: the kind that reshapes perception, redirects attention, and persuades an audience to believe in a reality that is not there. From its earliest ideas, Inference-Based Cognitive Behavioral Therapy (ICBT) drew on this logic of illusion. Magicians understand how attention can be redirected, how a fictive layer can be projected over [...]
