Magnitude of teacher expectancy effects on pupil IQ as a function of the credibility of expectancy induction: A synthesis of findings from 18 experiments
Raudenbush synthesised 18 experiments that induced teacher expectations about pupil IQ and found an average of about 0.11 standard deviations, close to zero where teachers had known their pupils for more than two weeks before the induction.
