Boyer & Lienard (B&L) elegantly elaborate the links between normal motivational systems and psychopathology and address the evolutionary and cultural context of ritualized behaviors. However, their model omits a key property of the security-motivation (hazard-precaution) system, and this property suggests that ritualized behavior may generate an alternate satiety signal by substituting, in place of uncertainty, a problem that is verifiably solvable.
