Subclaims¶

q2 i? In the Rosenthal and Jacobson study as the article recounts it, students falsely identified as about to make large academic gains ended up performing significantly better than peers for whom no such suggestion was seeded. → Gehlbach 2018

Evidence¶

Gehlbach, H., & Vriesema, C. C. (2018). Meta‐bias: A practical theory of motivated thinking. Educational Psychology Review. https://doi.org/10.1007/s10648-018-9454-6

q2 · i? · theoretical · r3

The article describes, citing Rosenthal and Jacobson (1968), teachers told that a predictive test identified students expected to make large leaps (in reality randomly assigned); teachers then behaved in ways that confirmed the planted pet theories. The article presents this as prior work illustrating confirmation bias.

"Consequently, these students ended up performing significantly better than their peers for whom no suggestion of substantial academic growth had been seeded by the experimenters."
