Vorhees (1989) argued critically that my reanalysis of the Collaborative Behavioral Teratology Study data was performed on the basis of improper unit of analyses. It was shown that his criticism is unwarranted. The erroneous logic underlying the collaborative study's conclusion that excellent reproducibility of data was obtained was confirmed.
