Research on psychic functioning, conducted over a two-decade period, i
s examined to determine whether the phenomenon has been scientifically
established. A secondary question is whether it is useful for governm
ent purposes. The primary work examined in this report was government-
sponsored research conducted at Stanford Research Institute (later kno
wn as SRI International) and at Science Applications International Cor
poration (SAIC). Using the standards applied to any other area of scie
nce, it is concluded that psychic functioning has been well establishe
d. The statistical results of the studies examined are far beyond what
is expected by chance. Arguments that these results could be due to m
ethodological flaws in the experiments are soundly refuted. Effects of
a magnitude similar to those found in government-sponsored research a
t SRI and SAIC have been replicated at a number of laboratories around
the world. Such consistency cannot be readily explained by claims of
flaws or fraud. The magnitude of psychic functioning exhibited appears
to be in the range between what social scientists call a small and a
medium effect It is thus reliable enough to be replicated in properly
conducted experiments, with sufficient trials to achieve the long-run
statistical results needed for replicability. A number of other patter
ns have been found, suggestive of how to conduct more productive exper
iments and to produce applied psychic functioning. For instance, it do
es not appear that a sender is needed. Precognition, in which the rele
vant information is known to no one until a future time, appears to wo
rk quite well. Recent experiments suggest that, if there is a psychic
sense, it works much as our other five senses do, by detecting change.
Physicists are currently grappling with an understanding of time, and
it may be that a psychic sense scans the future for major change, muc
h as our eyes scan tile environment for visual change or our ears allo
w us to respond to sudden changes in sound. The author recommends that
future experiments focus on understanding how psychic functioning wor
ks and on how to make it as useful as possible. There is little benefi
t in continuing experiments designed to offer proof, since there is li
ttle more to be offered to anyone who does not accept the current coll
ection of data.
