Often thought of as a benign and self-limited condition, hiccups can become persistent or intractable, and thus be associated with substantial morbidity and distress. In such cases, an underlying etiology is often present, and may be overlooked. Debilitating hiccups can present a major challenge to optimal symptom management. Various causes ...

The fateful combination of (i) the Dunning-Kruger effect (ignorance of one's own ignorance) with (ii) the nonlinear dynamics of the echo-chamber between reviewers and editors fuels a self-reinforcing collective delusion system that sometimes spirals uncontrollably away from objectivity and truth. Escape from this subconscious meta-ignorance is a formidable challenge but ...
