Abstract

Attempted a 2-series replication of the finding by S. R. Feather and R. Brier (see record 1969-13486-001) that outcomes on precognition runs, arbitrarily divided between them, varied depending on who scored ("checked") the runs. Two measures of checker influence were used in an experiment involving 67 Ss (aged 16-50 yrs). Series I found significant evidence of checker influence on one measure and indirect evidence on the other. Series II found both measures significant but only when checkers were not blind to Ss' predictions of who the checker would be. The results of these not-blind data resembled those of Series I, also checked under not-blind conditions. It is suggested that although the data best support the view that the checkers were the psi sources in these experiments, there is secondary evidence for psi from the Ss.
