 The two schools of heuristics  (section 7)  reach sharply different conclusions about human rationality. Yet, unlike bakers, their disagreement involves the meaning of ‘rationality’ and how we ought to appraise human judgment and decision making. The “rationality wars” are not the result of “rhetorical flourishes” concealing a broad consensus (Samuels, Stich, &amp; Bishop 2002), but substantive disagreements  (section 7.2)  that are obscured by ambiguous use of terms like ‘rationality’.
