Researchers at the University of Melbourne under the leadership of Piers Howards. conducted a number of studies which show that people can regularly detect changes without necessarily being able to identify what has changed. The paper “Detecting Unidentified Changes” was published January 13, 2014 in the on-line journal PLUS_ONE. This phenomena, called “change blindness” has been identified before but this is the first scientific study to verify its exact nature, It gives the person the impression that they know something “without knowing”, in other words knowing something but has no idea why or how he/she knows it. The persons who experienced this phenomena felt that is was similar to a sixth sense, by the fact that they sense information that did not have before and thus thought it to be a “magic” way of receiving that information. The study showed that the sensing ability is real but has nothing to do with a magic 6th sense and can be explained as a known process.
