An unconscious form of precognition that can be demonstrated in controlled conditions using techniques commonly used in psychophysiology. The effect is small but the findings have been widely replicated. 

The Princeton Engineering Anomalies Research (PEAR) laboratory was founded in 1979 by Robert Jahn and carried out ground-breaking research in psychokinesis and remote viewing for nearly three decades.

Experimental and anecdotal evidence suggests that psi can sometimes be used to advantage in gambling and financial speculation.

Before use of psychedlic drugs was banned in the 1960s, efforts were made to verify experimentally indications that the drug state is conducive to ESP experiences. A gradual easing of restrictions means this research could soon resume.

An experimental form of ESP that emerged in the late 1960s, in which a suitably trained person attempts in a meditative state to visualise the topography of a distant scene. A considerable degree of success has been demonstrated by three scientific groups, one funded by the US military. 

Ground-breaking 1884 paper by physiologist and psi researcher Charles Richet, devoted mainly to his use of statistics in telepathy experiments, an approach that became fully established only in the 1930s. 

Limited but significant psi research has been carried out in Russia since the 19th century.

The sense of knowing when one is being stared at is commonly reported, notably by police and other professionals involved in surveillance activities. Recent experimental investigations suggest that the phenomenon is real.
