A Lunar Modulation Effect on Retro-PK?
It has been thought that one way in which we might come to better understand (and perhaps eventually predict) the workings of psi phenomena is to search for any physical variables whose changes might be connected in some way with psi performance, and might therefore have a modulating effect on psi. One possible variable that has come to light in recent years is the Earth’s own internally-generated magnetic field, which studies suggest may decrease successful ESP performance as it increases in intensity (Persinger, 1989). A few recent studies are beginning to suggest the possibility that there may be another, lesser-known variable: certain phases of the monthly lunar cycle.
A great deal of myth and folklore has been traditionally associated with the phases of the moon throughout many human cultures since ancient times (Guiley, 1991). For example, in Celtic lore, midnight at the time of a full moon was considered “the witching hour,” and people were assumed to turn into werewolves under the full moon. Certain major holidays in the Christian and Jewish religions (Easter and Passover, respectively) are timed according to the lunar cycle. Even the term “lunatic” derives from the ages-old assumption that the light of the full moon made people crazy. In order to separate fact from fiction, several psychological studies have been done over the past few decades to see if any kind of human activity (e.g., murders, suicide attempts, crimes, trauma & mental hospital admissions, traffic accidents, stock market activity) might be tied in some way to the lunar cycle. Some of these studies found positive indications (Alonso, 1993; Geller & Shannon, 1976; Lieber & Sherin, 1972) while others found none (Coates et al., 1989; Culver et al., 1988; Rotton & Kelly, 1985), suggesting that any possible relation between the moon and human behavior was unclear and that the case was still up in the air.
The examination of the moon’s effects was first extended to psi when Northwestern University neurologist Andrija Puharich (1973) examined his subject’s performance on telepathy card tests in relation to the lunar cycle to test his hypothesis that ESP performance might be linked to gravitational forces (like those exerted by the moon on the tides of waves). Puharich found that success in telepathy tended to increase towards the time of the full moon, decreased at the quarter-moons, then increased again at new moon (pp. 281 – 289). Puharich’s study turned out to be an isolated affair, and examination of psi in relation to the moon did not arise again until two decades after, when Drs. Dean Radin and Jannine Rebman (1998), then of the University of Nevada, Las Vegas, examined four years of gaming data provided to them by an executive of a major Las Vegas casino (a rare opportunity, as casinos often guard their data like the gold of Fort Knox) to explore the possibility that people might use psi ability in the casino to help them win. Radin and Rebman found that the cash out winning percentages on five kinds of casino games (roulette, blackjack, craps, keno, & slot machines) tended to be the highest in the six days surrounding the time of the full moon to a suggestive degree by statistical standards. In addition, three of those five (roulette, keno, & slots) were highest within 1 day of the full moon, and the odds of this occurring by chance alone are about 2,000 to 1. These winning percentages also appeared to be coupled to certain geophysical factors (activity of the Earth’s magnetic field, sunspot number, and radio emissions from the sun) that fluctuated in time with the lunar cycle, suggesting that any effect the full moon has on psi and human behavior is not likely to be due to the moon itself, but rather to environmental factors that keep rather closely in sync with the lunar cycle. Another interesting finding when looking at these environmental factors is that the Earth’s magnetic field activity tends to decrease towards the full moon. When one then considers the finding that most of the gaming payout winnings were highest around the full moon, this may represent an indirect suggestion of the inverse relation between ESP and the Earth’s magnetic field (i.e., the former increases as the latter decreases, as mentioned). Dr. Radin (1997) republished this psi in the casino study in his book The Conscious Universe (Ch. 11), and in it he also mentions additional studies in which lottery winnings were found to decrease with the Earth’s magnetic field in years when the Earth’s field and the lunar cycle matched each other (i.e., the field increased at full moon), again suggesting the inverse ESP-Earth field relation.
