 Scientific TT, henceforth STT, holds that folk psychology is the result of evidence-driven scientific theorizing on the part of young children (Gopnik &amp; Wellman 1992; Gopnik 1996; Gopnik &amp; Meltzoff 1997). It proposes that each normally developing child forges and revises their own theory of mind using the same rational theory-construction methods that adults use when forging and revising mature scientific theories.
