Teachers' expectancies: Determinants of pupils' IQ gains
Rosenthal and Jacobson told teachers in eighteen classrooms that about a fifth of their children showed unusual potential for intellectual gains. The children named had in fact been selected at random. Eight months later they showed significantly greater IQ gains than the control children. The effects of teachers' expectancies operated mainly among the younger children.
