Book Review: Willpower

Review of Baumeister & Tierney's Willpower. Scott is disappointed the book just praises ego depletion as revolutionary while ducking the live controversy, and supplies that controversy himself: Kurzban's metabolic-math takedown (glucose can't be the limited resource; mouth-rinsing works without ingestion), the marshmallow-test replication failures and trust/IQ confounds, Carol Dweck's 'willpower only depletes if you think it does,' and the note that 'Baumeister's theory failed what sounds like a formal replication.' He then offers his own tentative model (an evolutionarily-novel executive override that is metabolically costly to sustain and budgeted like money or exercise-fatigue, plus the drug puzzle of Adderall/modafinil). Because the post foregrounds the skeptical case and the replication failure rather than relying on ego depletion, no replication caveat applies -- it's a critique, and a prescient one for 2015.

Quality 71 · Strong. A strong, honest, synthesizing book review -- more useful than the book, supplying the controversy the book omitted, plus three original analogies (exercise-fatigue, money-budgeting, executive-override) and his own model. Strong; not field-defining.

Claude’s paradigm shift 42 · Moderate. Moderate. The budgeting/executive-override synthesis is a fresh take, but the piece is fundamentally a review of others' work.

Real-world impact 2 · Minor. A strong, synthesizing review more useful than the book — supplying the ego-depletion controversy Baumeister ducked (Kurzban's metabolic takedown; the marshmallow replication failures) plus three original analogies and his own model. Conceptual influence within psychology discourse, no material change — low RWI.
