Investigating the Nature of Intangible Brain-Machine Interaction

The hypothesis that direct human intention can modulate the concurrent outcomes of a stochastic process has been under test for over 30 years, surrounded by inconclusive evidence and a great amount of ambiguity. An increased interest has recently and prematurely risen concerning possible scientific applications of such effects. The amassed information around the purported phenomena, as presented in a meta-analysis [1], is thoroughly re-examined here through the application of several recognised mathematical tools. It is shown that there exists no validation of the hypothesis of brain-machine interaction precisely in absence of interface devices. It is concluded that any evidence in favour of the alleged intangible brain-machine effects, must have resulted from unintended errors during data collection and treatment, known as “the experimenter expectancy effect”.
