Chapter 1: Further Reading
Essential Sources
Forer, B. R. (1949). "The fallacy of personal validation: A classroom demonstration of gullibility." Journal of Abnormal and Social Psychology, 44(1), 118–123. The original Barnum effect study. Short, readable, and still cited in every psychology textbook. Demonstrates how easily people accept generic personality descriptions as personally valid.
Lilienfeld, S. O., Lynn, S. J., Ruscio, J., & Beyerstein, B. L. (2010). 50 Great Myths of Popular Psychology: Shattering Widespread Misconceptions about Human Behavior. Wiley-Blackwell. The closest existing book to this one. Published before the social media era but still the gold standard for systematic evaluation of popular psychology claims. Chapters on the Barnum effect, learning styles, and many other topics we cover.
Kahan, D. M. (2013). "Ideology, motivated reasoning, and cognitive reflection." Judgment and Decision Making, 8(4), 407–424. The key paper on identity-protective cognition. Explains why intelligent people can be more resistant to correcting identity-relevant beliefs.
Recommended Reading
Risen, J. L. (2016). "Believing what we do not believe: Acquiescence to superstitious beliefs and other powerful intuitions." Psychological Review, 123(2), 182–207. Fascinating paper on why people can simultaneously know that something (like astrology) is not real and still be influenced by it. Relevant to understanding how pop psychology beliefs persist alongside skepticism.
Mercier, H., & Sperber, D. (2017). The Enigma of Reason. Harvard University Press. A provocative book arguing that human reasoning evolved not for finding truth but for persuasion and social argument. Provides deep context for why we're better at defending our existing beliefs than updating them.
Dunning, D. (2011). "The Dunning-Kruger effect: On being ignorant of one's own ignorance." Advances in Experimental Social Psychology, 44, 247–296. Relevant to understanding how confidence in pop psychology claims can be highest when knowledge is lowest.
Markus, H. R., & Kitayama, S. (1991). "Culture and the self: Implications for cognition, emotion, and motivation." Psychological Review, 98(2), 224–253. Classic paper on how cultural context shapes self-concept. The need for self-knowledge described in this chapter is culturally inflected — it is particularly strong in Western, individualist cultures.
