Several recent studies have employed a tacit precognition protocol to test the notion that extra-sensory perception may occur on a nonintentional basis, drawing inspiration from psi theories such as Stanford’s psi-mediated instrumental response (PMIR) model. After remarkable initial success, outcomes have subsequently become more inconsistent. One possible reason for the observed variability in results is that they were conducted by different experimenters. The current study therefore considered a number of dimensions regarding participants’ interaction with either a male or female experimenter. 52 participants took part in 12 nonintentional precognition trials and a positive or negative outcome task contingent on their performance. The total number of precognitive hits participants scored was marginally above the mean chance expectation but failed to reach statistical significance. There were significant positive correlations between participants’ precognition scores and their ratings of the positivity of their interaction with the experimenter, their rapport with the experimenter and their level of relaxation. There was also a notable difference between the two experimenters with respect to the relationships between their participant-experimenter interaction ratings and participants’ tacit precognition scores; all correlations were in the predicted direction for the female experimenter, but in the opposite direction for the male experimenter.
