In an effort to further explore ostensible macroscopic psychokinesis (macro-PK) effects like those previously reported by Batcheldor (1966), Bourgeois (1994), Owen and Sparrow (1976), and Ullman (2001) in a sitter group setting, the first author designed and conducted a series of fifteen experimental sessions in which sitters claiming exceptional abilities attempted to generate a pseudo-spirit named "Daniel," to whom physical phenomena were attributed. To explore possible physical correlates of macro-PK, two approaches to measurement were utilized. In the first, sample data (...) from a local random number generator (RNG) continuously running as part of the Global Consciousness Project were extracted and examined for statistical deviations from randomness occurring in conjunction with the sitter group sessions. In the second, the Multi-Energy Sensor Array (MESA) was used to collect onsite environmental data during one of the sessions. While displays of ostensible macro-PK were observed during several of the sitter group sessions, the RNG data did not show a significant overall correlation with the sessions. The MESA data indicated notable drops in infrared and visual light, as well as changes in DC magnetic field strength, that are comparable to those observed in field studies of haunts.
