As paranormal activity can’t be proven, it is not viewed as a subject that can be investigated thoroughly through science. There are no facts or proof to work with regarding a phenomenon that is based on feelings of presence by supernatural beings or ghosts. This creates many discussions within scientific circles.
As all scientists are sceptical about the presence of paranormal activities and ghosts, believers of the phenomena regularly try to prove and build facts on these happenings. With many researchers and investigators working on the topic of the paranormal, there has never been factual evidence presented in any form to validate any form of paranormal activity.
Sceptical scientists look at and advocate investigation into claims of paranormal phenomena by applying scientific methods to reach rational explanations of the phenomena to account for the paranormal claims.
They take into account the alleged paranormal activities and occurrences which are sometimes hoaxes or misinterpretations of the natural explanations of the activity. An organisation that is at the forefront of sceptical scientific investigations in the phenomenon is the Committee for Sceptical Inquiry. They aim to publicise the scientific approach towards claims of paranormal activities.
Richard Wiseman who works for the Committee draws attention to possible alternative explanations for perceived paranormal activities in many articles spanning over years of writing. Some of his research has proven interesting facts such as that 15% of the human race believe they have experienced the presence of ghosts or other supernatural beings.
It is believed by many scientists that feeling a presence or hearing a presence is an activity within our own brains that create these sensations. It has been stated that these experiences could be explained by stimulating the brain with weak magnetic fields.
An investigator with a background in illusion (James Randi) has said the simplest explanation for those claiming these experiences is often trickery.
These opinions by scientists are regarded by many as evidence of non-existence in the paranormal and its activities. Many activities have been proven to be hoaxes, yet there are still many unexplained happenings throughout the world that cannot be denied or verified by scientists.
