Parapsychologist Rupert Sheldrake carried out a number of experiments on the effect in the 2000s, and reported subjects exhibiting a weak sense of being stared at, but no sense of not being stared at [REF].
Writing after another skin conductance test in 2004 showed a negative result, Lobach & Bierman concluded that "the staring paradigm is not the easily replicable paradigm that it is claimed to be" [REF].
