New research seems to go some way to proving that the metal structure of a car or any other vehicle which forms what is known as a Faraday cage, could be responsible for the phenomenon that drives normally respectable individuals to lose their temper behind the wheel. The scientists responsible for the research believe that the driver may literally be a victim of circumstance and that far from bringing his emotional state into the car it is the car that creates or helps to create that emotional and negatively charged condition.
Shobhna Mukherjee in charge of the study group explained the rationale behind the research: "A great deal is known about how a Faraday cage keeps stuff out - in other words its ability to shield a person from such things as lightning, radio waves or electromagnetic radiation - but far less work has been done on examining how effectively it keeps stuff in. We became interested in this idea as a result of recent studies into the application of magnetoencephalography (MEG) in the detection of schizophrenia. What those studies have shown is that, because of the inextricable connection between magnetism and electricity, even the tiny electrical charge produced by neurons creates a magnetic field. We think a Faraday cage may not only retain certain psychological and emotional states but also reinforce them. There is a long way to go but we think we may be getting close to finding an explanation for this otherwise irrational behaviour."
