The ability to detect something different or wrong has nothing to do with a sixth sense but subtle clues we don’t even consciously notice.
A year-long University of Melbourne study, published in the journal Plos One, found that people could reliably detect a change in their surroundings, even if they could not accurately describe what that change was.
However, the research concluded that this was not due to any kind of supernatural ability, but rather from cues picked up from more conventional senses such as sight.
Researchers tested subject with photographs and asked whether a change had occured from one picture to another.
The results showed that while the subjects could “sense” a change had occurred, they could not verbalise what it was.
Some of the subjects, and lots of people, will say they possessed a sixth sense, or extrasensory perception, but it’s nothing so mysterious. Let’s give credit to our brain and our perception to notice something off in the surroundings. This is an evolutionarily adapted instinct. It’s not paranormal. It’s NORMAL. Though some are better at it than others.
