In his target article on “Indoctrination in Introduction to Psychology,” Bartels proposes that in introductory textbooks of psychology studies and their results are systematically presented in such a way that they tend to correspond to left-liberal political positions and that the state of psychological knowledge is reflected in a correspondingly distorted way.

Second, he draws an invalid causal inference from a supposed liberal majority in the psychological community to their representation of psychological content in textbooks. And third, he assigns introductory textbooks a function that we believe they do not have. Nonetheless, we welcome the discussion of how best to teach critical reflective thinking in psychology courses.
