Beschreibungen/Notizen
R. Rosenthal (see 43:8) presented 4 arguments attempting to show that the 5 experiments by T. X. Barber, et al. (see 43:8) cannot be viewed as serious efforts to replicate the R. Rosenthal and K. Fode (see 38:3) study. These arguments are shown to be invalid. Rosenthal's critique also presented a postmortem analysis of the Barber, et al., data. A further look at Rosenthal's analysis indicates that the Barber, et al., experiments cannot be interpreted as confirming the E bias hypothesis that Es' obtain results in line with their expectancies. It is concluded that the E bias effect is very difficult to demonstrate.
